Abdominal and pelvic CT scan with contrast for injury, foreign bodies, or tumors [HCPCS 74177]

Computerized tomography, also referred to as a CT scan, uses special x-ray equipment and computer technology to produce multiple cross-sectional images of the abdomen and pelvis. The patient is positioned on the CT examination table. An initial pass is made through the CT scanner to determine the starting position of the scans. The CT scan is then performed. As the table moves slowly through the scanner, numerous x-ray beams and electronic x-ray detectors rotate around the abdomen and pelvis. The amount of radiation being absorbed is measured. As the beams and detectors rotate around the body, the table is moved through the scanner. A computer program processes the data which is then displayed on the monitor as two-dimensional cross-sectional images of the abdomen or pelvis. The physician reviews the data and images as they are obtained and may request additional sections to provide more detail on areas of interest.

Abdominal ultrasound (complete) [HCPCS 76700]

A real time abdominal ultrasound is performed with image documentation. The patient is placed supine. Acoustic coupling gel is applied to the skin of the abdomen. The transducer is pressed firmly against the skin and swept back and forth over the abdomen and images obtained. The ultrasonic wave pulses directed at the abdomen are imaged by recording the ultrasound echoes. Any abnormalities are evaluated to identify characteristics that might provide a definitive diagnosis. The physician reviews the ultrasound images of the abdomen and provides a written interpretation.

Head or brain CT scan without contrast to examine injury, foreign bodies, or tumors [HCPCS 70450]

Computerized tomography, also referred to as a CT scan, uses special x-ray equipment and computer technology to produce multiple cross-sectional images of the region being studied. In this study, CT scan of the head or brain is performed. The patient is positioned on the CT examination table. An initial pass is made through the CT scanner to determine the starting position of the scans after which the CT scan is performed. As the table moves slowly through the scanner, numerous x-ray beams and electronic x-ray detectors rotate around the body region being examined. The amount of radiation being absorbed is measured. As the beams and detectors rotate around the body, the table is moved through the scanner. A computer program processes the data and renders the data in two-dimensional cross-sectional images of the body region being examined. This data is displayed on a monitor. The physician reviews the data as it is being obtained and may request additional sections to provide more detail of areas of interest.

Imaging of pelvis by ultrasound through vagina [HCPCS 76830]

A transvaginal ultrasound is performed to evaluate the non-pregnant uterus and other pelvic structures. Conditions that may be evaluated by transvaginal ultrasound include infertility, abnormal bleeding, unexplained pain, congenital anomalies of the ovaries and uterus, ovarian cysts and tumors, pelvic inflammatory disease, bladder abnormalities, and intrauterine device (IUD) location. The patient is asked to empty the bladder and then lies back with the feet in stirrups. A protective cover is placed over the transducer and acoustic coupling gel is applied. The transducer is inserted into the vagina. Images of the uterus, ovaries, and surrounding pelvic structures are obtained from different orientations of the transducer. The ultrasonic wave pulses directed at the pelvic structures are imaged by recording the ultrasound echoes. The uterus is examined and endometrial thickness is determined. The ovaries are examined and any ovarian masses are carefully evaluated. The bladder and other pelvic structures are examined and any abnormalities are noted. The physician reviews the transvaginal ultrasound images and provides a written interpretation.

Lab analysis of urine specimen by dipstick with microscope (automated) [HCPCS 81001]

A urinalysis is performed by dip stick or tablet reagent for bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, and/or urobilinogen. Urinalysis can quickly screen for conditions that do not immediately produce symptoms such as diabetes mellitus, kidney disease, or urinary tract infection. A dip stick allows qualitative and semi-quantitative analysis using a paper or plastic stick with color strips for each agent being tested. The stick is dipped in the urine specimen and the color strips are then compared to a color chart to determine the presence or absence and/or a rough estimate of the concentration of each agent tested. Reagent tablets use an absorbent mat with a few drops of urine placed on the mat followed by a reagent tablet. A drop of distilled, deionized water is then placed on the tablet and the color change is observed. Bilirubin is a byproduct of the breakdown of red blood cells by the liver. Normally bilirubin is excreted through the bowel, but in patients with liver disease, bilirubin is filtered by the kidneys and excreted in the urine. Glucose is a sugar that is normally filtered by the glomerulus and excreted only in small quantities in the urine. Excess sugar in the urine (glycosuria) is indicative of diabetes mellitus. The peroxidase activity of erythrocytes is used to detect hemoglobin in the urine which may be indicative of hematuria, myoglobinuria, or hemoglobinuria. Ketones in the urine are the result of diabetic ketoacidosis or calorie deprivation (starvation). A leukocyte esterase test identifies the presence of white blood cells in the urine. The presence of nitrites in the urine is indicative of bacteria. The pH identifies the acid-base levels in the urine. The presence of excessive amounts of protein (proteinuria) may be indicative of nephrotic syndrome. Specific gravity measures urine density and is indicative of the kidneys' ability to concentrate and dilute urine. Following dip stick or reagent testing, the urine sample may be examined under a microscope. The urine sample is placed in a test tube and centrifuged. The sediment is resuspended. A drop of the resuspended sediment is then placed on a glass slide, cover-slipped, and examined under a microscope for crystals, casts, squamous cells, blood (white, red) cells, and bacteria.

Lab analysis to evaluate kidney function via a blood test panel [HCPCS 80069]

A renal panel is obtained for routine health screening and to monitor conditions such as diabetes, renal disease, liver disease, nutritional disorders, thyroid and parathyroid function, and interventional drug therapies. Tests in a renal panel include glucose or blood sugar; electrolytes and minerals as sodium, potassium, chloride, total calcium, and phosphorus; the waste products blood urea nitrogen (BUN) and creatinine; a protein called albumin; and bicarbonate (carbon dioxide, CO2) responsible for acid base balance. Glucose is the main source of energy for the body and is regulated by insulin. High levels may indicate diabetes or impaired kidney function. Sodium is found primarily outside cells and maintains water balance in the tissues, as well as nerve and muscle function. Potassium is primarily found inside cells and affects heart rhythm, cell metabolism, and muscle function. Chloride moves freely in and out of cells to regulate fluid levels and help maintain electrical neutrality. Calcium is needed to support metabolic processes, heart and nerve function, muscle contraction, and blood clotting. Phosphorus is essential for energy production, nerve and muscle function, and bone growth. Blood urea nitrogen (BUN) and creatinine are waste products from tissue breakdown that circulate in the blood and are filtered out by the kidneys. Albumin, a protein made by the liver, helps to nourish tissue and transport hormones, vitamins, drugs, and calcium throughout the body. Bicarbonate (HCO3) may also be referred to as carbon dioxide (CO2) maintains body pH or the acid/base balance. A specimen is obtained by separately reportable venipuncture. Serum/plasma is tested using quantitative chemiluminescent immunoassay or quantitative enzyme-linked immunosorbent assay.

Lab analysis to evaluate the clotting time in plasma specimen and monitor drug effectiveness [HCPCS 85610]

Prothrombin time (PT) measures how long it takes for blood to clot. Prothrombin, also called factor II, is one of the clotting factors made by the liver and adequate levels of vitamin K are needed for the liver to produce sufficient prothrombin. Prothrombin time is used to help identify the cause of abnormal bleeding or bruising; to check whether blood thinning medication, such as warfarin (Coumadin), is working; to check for low levels of blood clotting factors I, II, V, VII, and X; to check for low levels of vitamin K; to check liver function, to see how quickly the body is using up its clotting factors. The test is performed using electromagnetic mechanical clot detection. If prothrombin time is elevated and the patient is not on a blood thinning medication, a second prothrombin time using substitution plasma fractions, also referred to as a prothrombin time mixing study, may be performed. This is performed by mixing patient plasma with normal plasma using a 1:1 mix. The mixture is incubated and the clotting time is again measured. If the result does not correct, it may be indicative that the patient has an inhibitor, such as lupus anticoagulant. If the result does correct, the patient may have a coagulation factor deficiency.

Lab analysis to identify the thyroid stimulating hormone (tsh) in blood specimen [HCPCS 84443]

A blood test is performed to determine levels of thyroid stimulating hormone (TSH). TSH is produced in the pituitary and helps to regulate two other thyroid hormones, triiodothyronine (T3) and thyroxin (T4), which in turn help regulate the body's metabolic processes. TSH levels are tested to determine whether the thyroid is functioning properly. Patients with symptoms of weight gain, tiredness, dry skin, constipation, or menstrual irregularities may have an underactive thyroid (hypothyroidism). Patients with symptoms of weight loss, rapid heart rate, nervousness, diarrhea, feeling of being too hot, or menstrual irregularities may have an overactive thyroid (hypothyroidism). TSH levels are also periodically tested in individuals on thyroid medications. The test is performed by electrochemiluminescent immunoassay.

Lab analysis to measure coagulation in plasma or whole blood specimen [HCPCS 85730]

This test may also be referred to as an activated PTT or aPTT. PTT may be performed to diagnose the cause of bleeding or as a screening test prior to surgery to rule-out coagulation defects. A silica and synthetic phospholipid PTT reagent is mixed with the patient plasma. The silica provides a negatively-charged particulate surface that activates the contact pathway for coagulation. Clot formation is initiated by adding calcium chloride to the mixture. Clotting time is measured photo-optically.

Lab analysis to measure complete blood cell count (red cells, white blood cell, and platelets), automated test and automated differential white blood cell count [HCPCS 85025]

An automated complete blood count (CBC) is performed with or without automated differential white blood cell (WBC) count. A CBC is used as a screening test to evaluate overall health and symptoms such as fatigue, bruising, bleeding, and inflammation, or to help diagnose infection. A CBC includes measurement of hemoglobin (Hgb) and hematocrit (Hct), red blood cell (RBC) count, white blood cell (WBC) count with or without differential, and platelet count. Hgb measures the amount of oxygen-carrying protein in the blood. Hct refers to the volume of red blood cells (erythrocytes) in a given volume of blood and is usually expressed as a percentage of total blood volume. RBC count is the number of red blood cells (erythrocytes) in a specific volume of blood. WBC count is the number of white blood cells (leukocytes) in a specific volume of blood. There are five types of WBCs: neutrophils, eosinophils, basophils, monocytes, and lymphocytes. If a differential is performed, each of the five types is counted separately. Platelet count is the number of platelets (thrombocytes) in the blood. Platelets are responsible for blood clotting. The CBC is performed with an automated blood cell counting instrument that can also be programmed to provide an automated WBC differential count.

Lab analysis to measure the amount of albumin, total and direct bilirubin, alkaline phosphatase, total protein, alanine amino transferase, and asparate amino transferase in blood specimen to evaluate liver function [HCPCS 800

A hepatic function panel is obtained to diagnose acute and chronic liver disease, inflammation, or scarring and to monitor hepatic function while taking certain medications. Tests in a hepatic function panel should include albumin (ALB), total and direct bilirubin, alkaline phosphatase (ALP), total protein (TP), alanine aminotransferase (ALT, SGPT), and aspartate aminotransferase (AST, SGOT). Albumin (ALB) is a protein made by the liver that helps to nourish tissue and transport hormones, vitamins, drugs, and calcium throughout the body. Bilirubin, a waste product from the breakdown of red blood cells, is removed by the liver in a conjugated state. Bilirubin is measured as total (all the bilirubin circulating in the blood) and direct (the conjugated amount only) to determine how well the liver is performing. Alkaline phosphatase (ALP) is an enzyme produced by the liver and other organs of the body. In the liver, cells along the bile duct produce ALP. Blockage of these ducts can cause elevated levels of ALP, whereas cirrhosis, cancer, and toxic drugs will decrease ALP levels. Circulating blood proteins include albumin (60% of total) and globulins (40% of total). By measuring total protein (TP) and albumin (ALB), the albumin/globulin (A/G) ratio can be determined and monitored. TP may decrease with malnutrition, congestive heart failure, hepatic disease, and renal disease and increase with inflammation and dehydration. Alanine aminotransferase (ALT, SGPT) is an enzyme produced primarily in the liver and kidneys. In healthy individuals ALT is normally low. ALT is released when the liver is damaged, especially with exposure to toxic substances such as drugs and alcohol. Aspartate aminotransferase (AST, SGOT) is an enzyme produced by the liver, heart, kidneys, and muscles. In healthy individuals AST is normally low. An AST/ALT ratio is often performed to determine if elevated levels are due to liver injury or damage to the heart or skeletal muscles. A specimen is obtained by separately reportable venipuncture. Serum/plasma is tested using quantitative enzymatic method or quantitative spectrophotometry.

Lab analysis to measure the amount of free PSA (prostate specific antigen) in serum specimen [HCPCS 84154]

Prostate specific antigen (PSA) is measured. PSA is a protein produced by normal prostate cells found in serum and exists in both free form and complexed with other proteins. In 84154, free PSA is measured, often in conjunction with total PSA, to provide an indirect measurement of complexed PSA.

Lab analysis to measure the amount of lipids (cholesterol and triglycerides) in blood specimen [HCPCS 80061]

"A lipid panel is obtained to assess the risk for cardiovascular disease and to monitor appropriate treatment. Lipids are comprised of cholesterol, protein, and triglycerides. They are stored in cells and circulate in the blood. Lipids are important for cell health and as an energy source. A lipid panel should include a measurement of triglycerides and total serum cholesterol and then calculate to find the measurement of high density lipoprotein (HDL-C), low density lipoprotein (LDL-C) and very low density lipoprotein (VLDL-C). HDL contains the highest ratio of cholesterol and is often referred to as ""good cholesterol"" because it is capable of transporting excess cholesterol in the blood to the liver for removal. LDL contains the highest ratio of protein and is considered ""bad cholesterol"" because it transports and deposits cholesterol in the walls of blood vessels. VLDL contains the highest ratio of triglycerides and high levels are also considered ""bad"" because it converts to LDL after depositing triglyceride molecules in the walls of blood vessels. A blood sample is obtained by separately reportable venipuncture or finger stick. Serum/plasma is tested using quantitative enzymatic method."

Lab analysis to measure the amount of total calcium, carbon dioxide (bicarbonate), chloride, creatinine, glucose, potassium, sodium, and urea nitrogen (BUN) in blood specimen [HCPCS 80048]

A basic metabolic blood panel is obtained that includes ionized calcium levels along with carbon dioxide (bicarbonate) (CO2), chloride, creatinine, glucose, potassium, sodium, and urea nitrogen (BUN). A basic metabolic panel with measurement of ionized calcium may be used to screen for or monitor overall metabolic function or identify imbalances. Ionized or free calcium flows freely in the blood, is not attached to any proteins, and represents the amount of calcium available to support metabolic processes such as heart function, muscle contraction, nerve function, and blood clotting. Total carbon dioxide (bicarbonate) (CO2) level is composed of CO2, bicarbonate (HCO3-), and carbonic acid (H2CO3) with the primary constituent being bicarbonate, a negatively charged electrolyte that works in conjunction with other electrolytes, such as potassium, sodium, and chloride, to maintain proper acid-base balance and electrical neutrality at the cellular level. Chloride is also a negatively charged electrolyte that helps regulate body fluid and maintain proper acid-base balance. Creatinine is a waste product excreted by the kidneys that is produced in the muscles while breaking down creatine, a compound used by the muscles to create energy. Blood levels of creatinine provide a good measurement of renal function. Glucose is a simple sugar and the main source of energy for the body, regulated by insulin. When more glucose is available than is required, it is stored in the liver as glycogen or stored in adipose tissue as fat. Glucose measurement determines whether the glucose/insulin metabolic process is functioning properly. Both potassium and sodium are positively charged electrolytes that work in conjunction with other electrolytes to regulate body fluid, stimulate muscle contraction, and maintain proper acid-base balance and both are essential for maintaining normal metabolic processes. Urea is a waste product produced in the liver by the breakdown of protein from a sequence of chemical reactions referred to as the urea or Krebs-Henseleit cycle. Urea is taken up by the kidneys and excreted in the urine. Blood urea nitrogen, BUN, is a measure of renal function, and helps monitor renal disease and the effectiveness of dialysis.

Lab analysis to measure the amount of total PSA (prostate specific antigen) in serum specimen [HCPCS 84153]

Prostate specific antigen (PSA) is measured. PSA is a protein produced by normal prostate cells found in serum and exists in both free form and complexed with other proteins. Total PSA is measured ad the total amount of both free and complexed forms. Total PSA levels are higher in men with benign prostatic hyperplasia (BPH), acute bacterial prostatitis, or prostate cancer. Total PSA is used to screen for prostate cancer and evaluate the response to treatment in those with prostate cancer, but cannot be used by itself to definitively diagnose prostate cancer.

Lab analysis via blood test to measure a comprehensive group of blood chemicals [HCPCS 80053]

A comprehensive metabolic panel is obtained that includes albumin, bilirubin, total calcium, carbon dioxide, chloride, creatinine, glucose, alkaline phosphatase, potassium, total protein, sodium, alanine amino transferase (ALT) (SGPT), aspartate amino transferase (AST) (SGOT), and urea nitrogen (BUN). This test is used to evaluate electrolytes and fluid balance as well as liver and kidney function. It is also used to help rule out conditions such as diabetes. Tests related to electrolytes and fluid balance include: carbon dioxide, chloride, potassium, and sodium. Tests specific to liver function include: albumin, bilirubin, alkaline phosphatase, ALT, AST, and total protein. Tests specific to kidney function include: BUN and creatinine. Calcium is needed to support metabolic processes such as heart function, muscle contraction, nerve function, and blood clotting. Glucose is the main source of energy for the body and is regulated by insulin. Glucose measurement determines whether the glucose/insulin metabolic process is functioning properly.

Mammography of both breasts (screening exam) [HCPCS 77067]

Bilateral screening mammography is done with computer-aided lesion detection (CAD), when performed. Mammography is the radiographic imaging of the breast using low-dose ionizing radiation. The x-rays used in mammography have a longer wavelength than those typically used for bone imaging. A screening mammogram is done on asymptomatic women for early breast cancer detection when there are no known palpable masses. This is done on both breasts with two views taken on each side. The breast is compressed between planes on a machine dedicated strictly to mammography. This evens out the dense tissue and holds the breast still for a better quality image. Computer-aided detection uses algorithm analysis of the image data obtained from the mammographic films, with or without digitization of the radiographic images. The mammographic picture of the breast is used by scanning the x-ray film with a laser beam, usually converting the scanned image of the analog film into digital data for the computer first, then employing a methodical, step-by-step pattern of analyzing the data on video display for unusual or suspicious areas.

Mammography of both breasts for diagnosis [HCPCS 77066]

These codes report diagnostic mammography of one breast or both breasts with computer-aided lesion detection (CAD), when performed. Mammography is the radiographic imaging of the breast using low-dose ionizing radiation. The x-rays used in mammography have a longer wavelength that those typically used for bone imaging. The test is done to detect tumors or cysts in women who have symptoms of breast disease or a palpable mass. The breast is compressed between planes on a machine dedicated strictly to mammography. This evens out the dense tissue and holds the breast still for a better quality image. Computer-aided detection uses algorithm analysis of the image data obtained from the mammographic films, with or without digitization of the radiographic images.

Physical therapy exercise to develop strength, endurance, range of motion, and flexibility (each 15 minutes) [HCPCS 97110]

Therapeutic exercise is the application of careful, graduated force to the body to increase strength, endurance, range of motion, and flexibility. Increased muscle strength is achieved by the deliberate overloading of a targeted muscle or muscle group and improved endurance is achieved by raising the intensity of the strengthening exercise to the targeted area(s) over a prolonged period of time. To maintain range of motion (ROM) and flexibility requires the careful movement and stretching of contractile and non-contractile tissue that may tighten with injury or neurological disease, causing weakness and/or spasticity. Therapeutic exercise can increase blood flow to the targeted area, reduce pain and inflammation, reduce the risk of blood clots from venous stasis, decrease muscle atrophy and improve coordination and motor control. Therapeutic exercise may be prescribed following acute illness or injury and for chronic conditions that affect physical activity or function.

Spinal x-ray of lower and sacral spine (minimum of 4 views) [HCPCS 72110]

A radiologic exam is done of the lumbosacral spine. Frontal, posteroanterior, and lateral views are the most common projections taken. X-ray uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures.

Cov-19 amp prb hgh thruput [HCPCS U0003]

Drug screening read by chemistry analyzers [HCPCS 80307]

A laboratory test is performed to detect the presence or absence of drugs classes in a patient’s system during a specific encounter. Presumptive screening is commonly done first, followed by test(s) for definitive drug identification as presumptive testing will not provide qualitative identification of individual drugs, nor quantitative levels present. A sample of blood or urine is obtained by separately reported procedure. Methods used include immunoassays, chromatography, and mass spectrometry.

Drug screening read by direct visual reading [HCPCS 80305]

Lab analysis by immunoassay to identify Strep (streptococcus) [HCPCS 87880]

A direct optical test to detect Streptococcus Group A (Strep A) by immunoassay is a rapid, qualitative test performed using lateral flow immunoassay. Strep A causes acute upper respiratory infection with the most common symptoms being pharyngitis (sore throat) and fever. If left untreated serious complications can occur including rheumatic fever and glomerulonephritis. This type of test is a rapid, qualitative test performed using lateral flow immunoassay. A throat swab is obtained. Two reagents are added to extract Strep A antigen from the specimen. A dipstick is added to the extracted sample. If Strep A antigen is present the test line and a control line will change color indicating a positive test. Another method uses a throat swab specimen inserted into a test cassette. Antigen extraction solutions are then mixed in a separate chamber of the tube and added to the swab chamber. If Strep A is present, a test line will change color as will a second control line.

Lab analysis of any culture (except urine, blood, or stool) to identify bacteria [HCPCS 87070]

A tissue sample besides blood, urine, or stool is collected and placed in a medium conducive to the growth of bacteria. The culture is examined for the growth of bacteria.

Lab analysis of stool culture to identify bacteria [HCPCS 87045]

A stool sample is collected and placed in a medium conducive to the growth of bacteria. The culture is examined for the growth of Salmonella and Shigella bacteria.

Lab analysis of urine culture to measure the amount of bacteria [HCPCS 87086]

"A laboratory test is performed to determine the presence or absence of bacterial colonies in urine and provide a colony count. Bacteria in urine may indicate an acute or chronic urinary tract infection (UTI) including pyelonephritis, cystitis, urethritis, or acute urethral syndrome. A urine sample is obtained by clean catch, mid-stream void or catheterization. Using a calibrated loop, the urine specimen is inoculated onto agar plates and incubated. Quantitative colony counts are determined and potential pathogens are identified. A colony count 10,000 cfu/mL is reported as ""organism present"" and may indicate an infection. Comingled flora of the urethra and mixed organisms in the colony counts are reported as ""mixed flora"" and most often represent contamination."

Lab analysis of wet mount to identify bacteria, fungi, or parasites [HCPCS 87210]

Lab analysis to evaluate an antimicrobial drug (antibiotic, antifungal, antiviral) by microdilution or agar dilution (each multi-antimicrobial, per plate) [HCPCS 87186]

A study is performed to determine the effectiveness of a specific antibiotic agent to a specific bacteria. The test is performed in an agar solution.

Lab analysis to identify antibodies for autoimmune disorder assessment (any method) [HCPCS 86235]

A blood test is performed to measure extractable nuclear antigen or antibody to it. One or more of these antibodies are typically elevated in autoimmune diseases such as Sjogren Syndrome, polymyositis, systemic lupus erythematosus, and progressive systemic sclerosis. Many are included in comprehensive panels that screen for multiple antibodies at one time. A blood sample is obtained by separately reportable venipuncture and tested by any method, particularly semiquantitative multi-analyte fluorescent detection. Report once for each antibody, such as: SSA (Ro) (ENA) Antibody, IgG; Jo-1 Antibody, IgG; scleroderma (Scl-70) (ENA) Antibody, IgG; Smith (ENA) Antibody, IgG; SSB (La) (ENA) Antibody, IgG; and RNP (U1) (Ribonucleic Protein) (ENA) Antibody, IgG.

Lab analysis to identify antibodies to Helicobacter pylori (gastrointestinal bacteria) [HCPCS 86677]

A laboratory test is performed to measure Helicobacter pylori antibodies. H. pylori is a bacterium found in contaminated food and water and may be spread person to person. The organism causes chronic inflammation of the gastrointestinal mucosa, primarily in the stomach and duodenum, which leads to erosion or ulcer formation. The seroconversion of IgA and IgG antibodies will occur together within about 60 days of exposure. Elevated titers to both IgA and IgG antibodies in the presence of symptoms may represent an active H. pylori infection. The antibody test should be confirmed with bacterial isolation or other diagnostic tests such as H. pylori breath test, or fecal antigen by EIA. It is also possible to test for IgM antibodies, however the clinical usefulness of this measurement has not been clearly established. A blood sample is obtained by separately reportable venipuncture. Serum is tested for IgA/IgG antibodies using semi-quantitative enzyme immunoassay and for IgM antibodies using semi-quantitative enzyme-linked immunosorbent assay.

Lab analysis to identify substances by immunoassay technique (multiple step method) [HCPCS 83516]

An immunoassay is performed to detect a chemical substance (analyte) other than an antigen or antibody produced by the body in response to an infectious agent. There are dozens of immunoassays for non-infectious antigens and antibodies that are reported with these codes. Examples of non-infectious diseases and disorders that may be worked up using these tests include: celiac disease, motor and sensory neuropathy, Crohn's disease or other inflammatory bowel disease, liver disease, thyroid disease. Examples of specific antigens and antibodies reported with these codes include: Asialo IgG and IgM, ganglioside IgG and IgM, gliadin IgA and IgG. Codes are reported for each immunoglobulin class or subclass tested using this technique, so for example when testing for gliadin IgA and IgG by immunoassay, the code would be reported twice. Qualitative or semiquantitative testing is performed. Qualitative tests detect only the presence or absence of the specific substance. Semiquantitative tests provide a rough estimate of the amount of the substance being tested.

Lab analysis to identify white blood cells (manual) with microscope [HCPCS 85007]

A blood smear is performed with microscopic examination with or without a manual differential WBC count. A blood smear is typically performed following an automated test that indicates the presence of abnormal or immature blood cells. It may also be performed when the physician suspects a condition that affects blood cell production, such as anemia. A blood sample is obtained by separately reportable venipuncture. A blood smear is prepared and examined under a microscope by a technician for immature or abnormal cells. The test is performed with a manual differential white blood cell (WBC) count. The technician examines and counts each of the five types of WBCs separately. Neutrophils comprise the majority of WBCs in healthy adults and are differentiated by cytoplasm with pink or purple granules. Eosinophils normally comprise 1-3% of total WBCs and are differentiated in stained smears by their large, red-orange granules. Elevated levels of eosinophils may indicate allergy or parasitic infection. Basophils normally comprise only 1% of total WBCs and are differentiated by their large black granules. Elevated levels of basophils may be indicative of certain leukemias, varicella (chicken pox) infection, or ulcerative colitis. Monocytes are the largest WBCs and act as scavengers to ingest (phagocytize) cellular debris, bacteria, and other particles. Lymphocytes produce antibodies (immunoglobulins) and are differentiated by their homogenous cytoplasm and smooth, round nucleus.

Lab analysis to measure blood count (hemoglobin) [HCPCS 85018]

A blood test is performed to determine hemoglobin (Hgb) which is a measurement of the amount of oxygen-carrying protein in the blood. Hgb is measured to determine the severity of anemia or polycythemia, monitor response to treatment for these conditions, or determine the need for blood transfusion. A blood sample is collected by separately reportable venipuncture or finger, heel, or ear stick. The sample may be sent to the lab or a rapid testing system may be used in the physician's office. Systems consist of a portable photometer and pipettes that contain reagent. The pipette is used to collect the blood sample from a capillary stick and the blood is automatically mixed with the reagent in the pipette. The photometer is then used to read the result which is displayed on the photometer device.

Lab analysis to measure coagulation function measurement of D-dimer (quantitative) [HCPCS 85379]

D-dimer testing for fibrin degradation products is performed to help rule out the presence of a thrombus. D-dimer tests are also used to rule-out hypercoagulability. D-dimer has a negative predictive value for these conditions which means that a negative result indicates that there is not an elevated level of fibrin degradation products present in the specimen. A positive result indicates an abnormally high level of fibrin degradation products which may be indicative of a thrombus. It is used to help diagnosis deep vein thrombophlebitis, pulmonary embolus, and stroke. The test is also used to evaluate for hypercoagulability which predisposes the patient to blood clots and to help diagnose disseminated intravascular coagulation (DIC) and monitor the effectiveness of DIC treatment.

Lab analysis to measure free testosterone (hormone) level in serum specimen [HCPCS 84402]

A blood test is performed to measure free testosterone levels. Testosterone is an androgen hormone secreted in the testes of men, ovaries of women, and the adrenal glands of both sexes. Testosterone helps promote protein synthesis and supports the growth of cells and tissue. This test is often performed in conjunction with sex hormone binding globulin. A blood sample is obtained by separately reportable venipuncture. Serum/plasma of adult males is tested using quantitative electrochemiluminescent immunoassay with the value derived from a mathematical expression using sex hormone binding globulin (SHBG). Serum/plasma of adult males may also be tested using quantitative equilibrium dialysis/high performance liquid chromatography-tandem mass spectrometry. Serum/plasma of children and adult females is tested using quantitative high performance liquid chromatography-tandem mass spectrometry/electrochemiluminescent immunoassay with the value also derived from a mathematical expression using sex hormone binding globulin (SHBG).

Lab analysis to measure free thyroxine (thyroid chemical) in serum specimen [HCPCS 84439]

A blood sample is obtained and levels of total thyroxin, thyroxine requiring elution as for testing in neonates or free thyroxine are evaluated. Thyroxine, also referred to as T4, is tested to determine whether the thyroid is functioning properly and is used to aid in the diagnosis of overactive (hyperthyroidism) or underactive (hypothyroidism) thyroid function. In free thyroxine levels are tested. Free thyroxine is the amount of active thyroxine in the blood. Free thyroxine levels are considered to be a more accurate indicator of thyroid function. All thyroxine tests use electrochemiluminescent immunoassay methodology.

Lab analysis to measure red blood cell concentration [HCPCS 85014]

A blood test is performed to determine hematocrit (Hct). Hematocrit refers to the volume of red blood cells (erythrocytes) in a given volume of blood and is usually expressed as a percentage of total blood volume. A blood sample is obtained by separately reportable venipuncture or finger, heel, or ear stick. Hct is calculated using an electronic cell counter.

Lab analysis to measure red blood cell sedimentation rate to detect inflammation (non-automated) [HCPCS 85651]

Lab test for Sedimentation rate

Lab analysis to measure the ammonia level [HCPCS 82140]

A blood test is performed to measure ammonia levels. Ammonia is a by product of protein metabolism and is normally converted to urea by the liver and excreted via the kidney. Elevated ammonia levels may result from cirrhosis or hepatitis. Symptoms of elevated ammonia levels are confusion, tremors, excessive sleepiness, or coma. Testing may be performed in disease states such as Reyes syndrome or liver failure. A blood sample is obtained by a separately reportable venipuncture or arterial access line. The specimen is then tested using colorimetry.

Lab analysis to measure the amount of blood gases [HCPCS 82803]

A laboratory test is performed to measure one or more components of blood gases. The homeostatic acid-base balance is measured as blood pHùthe number of hydrogen ions (H+) dissolved in the blood. Partial pressure of carbon dioxide (pCO2) is the amount of carbon dioxide dissolved in the blood and reflects how well the lungs can move CO2 out of the body. Partial pressure of oxygen (pO2) is the level of oxygen dissolved in the blood and reflects the exchange of oxygen molecules in the alveoli. Bicarbonate (HCO3) is calculated from pH and pCO2 and is the metabolic component of acid-base balance reflecting the kidney's response to changes in pH. Oxygen saturation (O2 Sat) is the percent of hemoglobin that is carrying oxygen. Calculated O2 saturation uses a mathematical model to determine the percentage of hemoglobin that is carrying oxygen based on the level of pO2. Blood gas monitoring may be performed to evaluate lung function; detect an acid-base imbalance; monitor metabolic, respiratory, and kidney disorders; and evaluate the effectiveness of treatment. A blood sample is obtained by separately reportable venipuncture, heelstick, arterial, or umbilical cord draw.

Lab analysis to measure the amount of blood in stool specimen by fecal hemoglobin determination and immunoassay [HCPCS 82274]

Lab analysis to measure the amount of C-reactive protein in serum to identify infection or inflammation [HCPCS 86140]

A blood test is performed to measure C-reactive protein (CRP) levels. This standard test has a wide value range. CRP is an acute phase protein, synthesized by the liver and released in response to inflammation and infection. The test is not diagnostic for any specific disease or condition but can be used as a marker to monitor the body's response to treatment(s) or to evaluate the need for further testing. Elevation of CRP levels may be found during pregnancy, with the use of oral contraceptives, or hormone replacement therapy. Diseases/conditions that cause an elevation of CRP include: lymphoma, arteritis/vasculitis, osteomyelitis, inflammatory bowel disease, rheumatoid arthritis, pelvic inflammatory disease (PID), systemic lupus erythematosus (SLE), acute infections, burns, surgical procedures, and organ transplants. A blood sample is obtained by separately reportable venipuncture. Serum in neonates is tested using immunoassay. Serum/plasma in all other patients is tested using quantitative immunoturbidimetric method.

Lab analysis to measure the amount of gammaglobulin (immune system protein) [HCPCS 82784]

A test is performed to measure immunoglobin levels in the blood or other body fluids, such as saliva or cerebral spinal fluid. Immunoglobins, also referred to as antibodies, are evaluated to help diagnose a variety of conditions including autoimmune diseases, allergies, or malignant neoplasms such as multiple myeloma or macroglobulinemia. In addition, immunoglobulin levels may be evaluated in patients with frequent infections to determine if there is a low level of immunoglobulin IgG. Immunoglobulins are also evaluated in patients with cancer or H. pylori infection to determine the effectiveness of treatment. There are five major types of antibodies. IgA antibodies are found in the nose, respiratory and digestive tracts, ears, eyes, and vagina. IgA protects the body surfaces from outside foreign substances. IgD is found in tissues lining the abdominal and thoracic cavity. IgE is found in the lungs, skin, and mucous membranes and reacts to substances commonly associated with allergies, such as food, pollen, dander, dust, fungus spores, etc. High levels of IgE are associated with allergies. IgG is found in all body fluids and is important in fighting bacterial and viral infections. There are four subclasses of IgG, designated as IgG1, IgG2, IgG3, and IgG4. These different subclasses protect against different types of infection. For example IgG1 is particularly effective in protecting the body from viral proteins, whereas IgG2 is more effective against certain types of bacterial infections. Individuals may have selective IgG subclass deficiencies characterized by low levels of one or two IgG subclasses with normal total IgG. IgM is found in blood and lymph and is important in fighting infection. A blood specimen is obtained by separately reportable venipuncture, a CSF sample is obtained by separately reportable spinal puncture, or saliva is collected. The methodology used to test immunoglobulin levels is dependent on the type of specimen and the immunoglobulin being tested.

Lab analysis to measure the amount of hepatitis A antibody, hepatitis B core antibody, hepatitis B surface antigen, and hepatitis C antibody in blood specimen to evaluate acute hepatitis [HCPCS 80074]

An acute hepatitis panel is obtained to detect and diagnose acute or chronic viral liver infections. Hepatitis A virus (HAV) is highly contagious but usually causes only a mild illness. HAV is found in contaminated food and water but may also be spread person to person by close physical contact. It does not cause a chronic infection and a vaccine is available. Hepatitis B virus (HBV) is found in blood and body fluids and is the most common hepatitis virus contracted. It is a chronic infection and a vaccine is available against HBV. Hepatitis C virus is also found in blood and body fluids, and is chronic, however no vaccine is yet available to protect against this virus. Tests in an acute hepatitis panel should include Hepatitis A antibody, IgM antibody (HAAb IgM Ab), Hepatitis B core antibody, IgM antibody (HBcAb IgM Ab), Hepatitis B surface antigen (HBsAg), and Hepatitis C antibody (by CIA or Interp). Hepatitis A Virus antibody, IgM develops 2-3 weeks post exposure and remains elevated for 2-6 months. Hepatitis B Virus core antibody, IgM is produced in response to the presence of Hepatitis B core antigen. It will be elevated with acute initial infection and during flare up of disease activity in chronic infection. Hepatitis B Virus surface antigen is a protein located on the surface of HBV. Elevated levels of HBsAg may be an early sign of exposure to the virus or indicate an acute or chronic infection. When testing for Hepatitis C antibody, it is not possible to distinguish whether elevated levels are due to active acute infection or a chronic disease state unless differentiated by further testing. A specimen is obtained by separately reportable venipuncture. Serum/plasma is tested using quantitative chemiluminescent immunoassay.

Lab analysis to measure the amount of protein in serum specimen [HCPCS 84165]

There are more sensitive tests available to detect these and similar disorders. A blood sample is obtained by separately reportable venipuncture. Serum is tested using electrophoretic fractionation and quantitation.

Lab analysis to measure the amount of substance by radioimmunoassay [HCPCS 83519]

Lab analysis to measure the amount of tacrolimus in blood specimen [HCPCS 80197]

A blood test is performed to measure tacrolimus levels. Tacrolimus, also known as Prograf is an immunosuppressant drug that affects the ability of certain white blood cells in the body to recognize and respond to transplanted body organs such as kidney, liver, heart and lung. The drug is administered intravenously, either alone or in combination with other immunosuppressant drugs. Tacrolimus has a narrow therapeutic range and blood levels may be assessed daily at the start of therapy, taper to 1-2 times per week and finally to once every 1-2 months. For routine monitoring the specimen is collected as a trough level, immediately prior to a scheduled dose and at least 12 hours after the previous dose. A blood sample is obtained by a separately reportable venipuncture. Whole blood is then tested using liquid chromatography-tandem mass spectrometry. Prograf may be tested with chromatographic or immunoassay technique and the results will be somewhat different. Make note of the technique used when comparing results with previous levels.

Lab analysis to measure the amount of total cortisol (hormone) [HCPCS 82533]

Cortisol is a glucocorticoid (steroid hormone) produced by the adrenal gland in response to stress. The hormone causes an elevation in blood glucose levels, a decrease in immune system function and aids in the metabolism of fats, proteins and carbohydrates. The test may be used to diagnose Cushing syndrome (elevated cortisol levels) or Addison disease (decreased cortisol levels). A blood or saliva test is performed to measure total cortisol (hydrocortisone) levels. A blood sample is obtained by separately reportable venipuncture. Serum or plasma is tested using quantitative chemiluminescent immunoassay or quantitative liquid chromatography-tandom mass spectrometry. A saliva sample is obtained by separately reportable oral swab using a saliva collection device. Saliva is tested using quantitative enzyme immunoassay.

Lab analysis to measure the amount of total digoxin in blood specimen [HCPCS 80162]

A laboratory test is performed to measure digoxin levels. Digoxin, also known as Lanoxin, is a cardiac glycoside that controls sodium and potassium levels in the cells. Digoxin is primarily prescribed to treat atrial fibrillation, atrial flutter, and congestive heart failure. The drug increases the strength of cardiac muscle contractions which increases cardiac output and lowers the heart rate and venous pressure. Digoxin has a narrow therapeutic window but antidotal treatment is available (Digibind, Digoxin Immune FAB). The test for total digoxin measures Fab fragment-bound (inactive) digoxin and free (active) digoxin. This test is primarily used to monitor digoxin therapy and should be drawn 8-12 hours following an oral dose. The test for free digoxin (80163) may be used to evaluate breakthrough digoxin toxicity in patients with renal failure, access the need for additional antidigoxin Fab, determine when to reintroduce digoxin therapy, and monitor patients with possible digoxin-like immune reactive factors. To measure free digoxin, a blood sample is obtained by separately reportable venipuncture 6-8 hours after the last dose. Serum is tested for total digoxin using immunoassay and for free digoxin using ultrafiltration followed by electrochemiluminescent immunoassay.

Lab analysis to measure the amount of total phenytoin in blood specimen [HCPCS 80185]

A blood test is performed to measure phenytoin total and phenytoin free levels. Phenytoin also known as Dilantin, Phenytek or Prompt, is an anticonvulsant prescribed to treat seizures and works by deceasing electrical activity in the brain. The drug may be administered orally or by injection. Phenytoin has a narrow therapeutic range and the patient should be monitored for both total and free phenytoin levels. Total phenytoin reflects the total serum concentration of the drug while free phenytoin levels reflect the unbound levels. Only the unbound levels are biologically active. Ninety (90) percent of the drug is typically highly bound and biologically inactive, but bound phenytoin is sensitive to displacement by other protein binding drugs which can elevate levels of free phenytoin in the blood. Blood concentration levels are monitored at regular intervals and also when breakthrough seizures occur, indicating possible low therapeutic levels. A blood sample is obtained by a separately reportable venipuncture. Blood serum is then tested using immunoassay.

Lab analysis to measure the amount of troponin (protein) in serum specimen [HCPCS 84484]

A blood test is performed to measure troponin levels. Troponins are regulatory proteins that facilitate contraction of skeletal and smooth muscle by forming calcium bonds. Troponin T binds to tropomyosin to form a complex. Troponin I binds to actin and holds the Troponin T-tropomyosin complex together. Elevation of troponins, coupled with cardiac symptoms such as chest pain are considered diagnostic for cardiac injury. This test is commonly ordered in the Emergency Department when a patient presents with possible myocardial infarction, and is then repeated at 6 hour intervals. It may be ordered with other tests that assess cardiac biomarkers such as CK, CK-MB, and myoglobin. A blood sample is obtained by separately reportable venipuncture. Serum/plasma is tested for Troponin T using quantitative electrochemiluminescent immunoassay. Serum is tested for Troponin I using chemiluminescent immunoassay.

Lab analysis to measure the amylase (enzyme) level in serum specimen [HCPCS 82150]

Laboratory testing for amylase may be performed on blood, urine, and other body fluids. Amylase is an enzyme responsible for the break down of starches into sugar molecules (disaccharides and trisaccharides) and eventually into glucose for energy use by the cells. Amylase is produced in saliva and the pancreas. Abnormal amylase levels may result from pancreatic inflammation or trauma, perforated peptic ulcer, ovarian cyst (torsion), strangulation ileus, macroamylasemia, mumps, and cystic fibrosis. A blood or body fluid sample is obtained. The sample is then tested using quantitative enzymatic methodology.

Lab analysis to measure the blood potassium level in blood specimen [HCPCS 84132]

A blood sample is obtained to measure potassium level. Potassium is a positively charged electrolyte that works in conjunction with other electrolytes, such as sodium, chloride, and carbon dioxide (CO2), to regulate body fluid, stimulate muscle contraction, and maintain proper acid-base balance. Potassium is found in all body fluids but mostly stored within cells, not in extracellular fluids, blood serum, or plasma. Small fluctuations in blood potassium, either too high (hyperkalemia) or too low (hypokalemia), can have serious, even life-threatening, consequences. Potassium level is used to screen for and monitor renal disease; monitor patients on certain medications, such as diuretics, as well as patients with acute and chronic conditions, such as dehydration or endocrine disorders. Because blood potassium affects heart rhythm and respiratory rate, it is routinely checked prior to major surgical procedures. Potassium is measured by ion-selective electrode (ISE) methodology.

Lab analysis to measure the creatine kinase (cardiac enzyme) level (MB fraction only) [HCPCS 82553]

Creatine kinase (CK) also known as, creatine phosphokinase (CPK), is an enzyme found in the heart, brain, skeletal muscle and certain other tissue. The subtypes are known as CK-MM found primarily in skeletal and heart muscle, CK-MB found in heart muscle and CK-BB located in the brain. CK circulating in blood rarely contains CK-BB but is largely comprised of CK-MM or CK-MB. Levels may be elevated following heart muscle damage (heart attack/myocardial infarction) and skeletal muscle injury (trauma, vigorous exercise). Statin drugs that lower cholesterol level and alcohol intake may cause elevated CK blood levels. Only creatine kinase (CK) MB fraction is measured. Testing for this isoenzyme can help identify heart muscle damage following a heart attack (myocardial infarction). A blood test is obtained by separately reportable venipuncture. Serum is tested using chemiluminescent immunoassay.

Lab analysis to measure the creatinine level in blood specimen to test for kidney function or muscle injury [HCPCS 82565]

Blood levels may be reduced with pernicious and other forms of anemia, and in individuals who follow a strict vegan diet, have chronic infections (such as HIV) and during pregnancy. A blood sample is obtained by separately reportable venipuncture. Serum is tested using quantitative chemiluminescent immunoassay.

Lab analysis to measure the direct bilirubin level [HCPCS 82248]

A laboratory test is performed to measure total or direct bilirubin. Bilirubin is a pigmented waste product normally produced when red blood cells (RBCs) break down. Non-water soluble (unconjugated) bilirubin is carried on albumin to the liver where it attaches to sugar molecules to become conjugated. Conjugated (direct) bilirubin is water soluble and able to pass from the liver to the small intestine. Further breakdown of bilirubin occurs in the small intestine and it is eventually eliminated in the feces in the form of stercobilin. Total bilirubin is the sum of conjugated (direct) and unconjugated bilirubin. A test for either conjugated or direct bilirubin or total bilirubin may be ordered to diagnose and monitor liver disorders, hemolytic anemia, and newborn (physiologic) jaundice. A blood sample is obtained by separately reportable venipuncture or heel stick. Other body fluids, including cerebral spinal fluid, may be collected and tested for total bilirubin. Serum/plasma is tested using quantitative spectrophotometry.

A blood or urine test is performed to measure inorganic phosphorus (phosphate) levels. Phosphate is an intracellular anion, found primarily in bone and soft tissue. It plays an important role in cellular energy (nerve and muscle function) and the building/repair of bone and teeth. Decreased levels are most often caused by malnutrition and lead to muscle and neurological dysfunction. Elevated levels may be due to kidney or parathyroid gland problems. A blood sample is obtained by separately reportable venipuncture. Serum/plasma is tested using quantitative spectrophotometry.

Lab analysis to measure the sodium level in urine specimen [HCPCS 84300]

A urine sample is obtained to measure sodium level. Sodium is a positively charged electrolyte that works in conjunction with other electrolytes, such as potassium, chloride, and carbon dioxide (CO2), to regulate fluid in the body and maintain proper acid-base balance. Sodium is an essential mineral in the body, necessary for maintaining normal metabolic processes, fluid levels, and vascular pressure. Sodium level is used to screen for and monitor elevated blood sodium (hypernatremia), low blood sodium (hyponatremia), and electrolyte imbalances. Sodium may be monitored in patients on certain medications, such as diuretics, that can cause electrolyte imbalance. Sodium is measured by ion-selective electrode (ISE) methodology.

Lab analysis to measure the total creatine kinase (cardiac enzyme) level in blood specimen [HCPCS 82550]

Creatine kinase (CK) also known as, creatine phosphokinase (CPK), is an enzyme found in the heart, brain, skeletal muscle and certain other tissue. The subtypes are known as CK-MM found primarily in skeletal and heart muscle, CK-MB found in heart muscle and CK-BB located in the brain. CK circulating in blood rarely contains CK-BB but is largely comprised of CK-MM or CK-MB. Levels may be elevated following heart muscle damage (heart attack/myocardial infarction) and skeletal muscle injury (trauma, vigorous exercise). Statin drugs that lower cholesterol level and alcohol intake may cause elevated CK blood levels. A blood test is performed to measure total creatine kinase (CK) levels. A blood specimen is obtained by separately reportable venipuncture. Serum or plasma is tested using quantitative enzymatic methodology.

Lab analysis to measure the total protein level in urine specimen [HCPCS 84156]

A urine test is performed to measure total protein levels. Protein is not normally found in urine and usually indicates damage or disease in the kidneys. Elevated levels are often present in patients with diabetes, hypertension, and multiple myeloma. A 24-hour or random urine sample is obtained and tested using quantitative spectrophotometry.

Lab analysis to measure the uric acid level in blood specimen [HCPCS 84550]

A blood test is performed to measure uric acid levels. Uric acid forms from the natural breakdown of body cells and the food we ingest. Uric acid is normally filtered by the kidneys and excreted in urine. Elevated blood levels may result from kidney disease, certain cancers and/or cancer therapies, hemolytic or sickle cell anemia, heart failure, cirrhosis, lead poisoning, and low levels of thyroid or parathyroid hormones. Levels may be decreased in Wilson's disease, poor dietary intake of protein, and with the use of certain drugs. A blood sample is obtained by separately reportable venipuncture. Serum/plasma is tested using quantitative spectrophotometry.

Lab analysis to measure the vitamin D-3 level in serum or plasma specimen [HCPCS 82306]

Blood levels of 25-hydroxyvitamin D are used to primarily to determine whether a deficiency of Vitamin D or abnormal metabolism of calcium is the cause of bone weakness or malformation. Vitamin D is a fat soluble vitamin that is absorbed from the intestine like fat, and 25-hydroxyvitamin D levels are also evaluated in individuals with conditions or diseases that interfere with fat absorption, such as cystic fibrosis, Crohn's disease, or in patients who have undergone gastric bypass surgery. A blood sample is obtained. Levels of 25-hydroxyvitamin D3 and 25-hydroxyvitamin D2 are evaluated using chemiluminescent immunoassay. The test results may be the sum of Vitamin D3 and D2 or the results may include fractions of D3 and D2 as well as the sum of these values.

Lab analysis to measure total testosterone (hormone) level in serum specimen [HCPCS 84403]

A urine test is performed to measure total testosterone level. Testosterone is an androgen hormone secreted in the testes of men, ovaries of women, and the adrenal glands of both sexes. Testosterone helps promote protein synthesis and supports the growth of cells and tissue. This test is often performed in conjunction with sex hormone binding globulin. A blood sample is obtained by separately reportable venipuncture. Serum/plasma of adult males is tested using quantitative electrochemiluminescent immunoassay with the value derived from a mathematical expression using sex hormone binding globulin (SHBG). Serum/plasma of adult males may also be tested using quantitative equilibrium dialysis/high performance liquid chromatography-tandem mass spectrometry. Serum/plasma of children and adult females is tested using quantitative high performance liquid chromatography-tandem mass spectrometry/electrochemiluminescent immunoassay with the value also derived from a mathematical expression using sex hormone binding globulin (SHBG).

Lab analysis to measure urea nitrogen level in serum or plasma specimen to assess kidney function (quantitative) [HCPCS 84520]

A blood sample is obtained to measure total (quantitative) urea nitrogen (BUN) level. Urea is a waste product produced in the liver by the breakdown of protein from a sequence of chemical reactions referred to as the urea or Krebs-Henseleit cycle. Urea then enters the bloodstream, is taken up by the kidneys and excreted in the urine. Blood BUN is measured to evaluate renal function, to monitor patients with renal disease, and to evaluate effectiveness of dialysis. BUN may also be measured in patients with acute or chronic illnesses that affect renal function. BUN is measured using spectrophotometry.

Lab analysis to screen for autoimmune disorders [HCPCS 86038]

A blood sample is obtained to screen for the presence of antinuclear antibodies (ANA) or to measure the concentration of antinuclear antibody in the blood, which is referred to as an ANA titer. Antinuclear antibodies are auto-antibodies that bind to structures within the nucleus of cells. Auto-antibodies are a type of antibody that is directed against the body's own tissues. The presence and concentration of antinuclear antibodies may indicate one of several autoimmune disorders that cause inflammation of body tissues including systemic lupus erythematosus, Sjorgren's syndrome, rheumatoid arthritis, polymyositis, scleroderma, Hashimoto's thyroiditis, juvenile diabetes mellitus, Addison disease, vitiligo, pernicious anemia, glomerulonephritis, and pulmonary fibrosis. When testing for antinuclear antibodies, the specimen is typically screened first using an enzyme-linked immunosorbent assay (ELISA) If the screening test is positive, that is if antinuclear antibodies are detected, a titer is then obtained. An antinuclear antibody titer is performed by diluting the blood sample with increasing amounts of a saline solution and retesting until antinuclear antibodies are no longer detectable. ANA titer is expressed as 1:10, 1:20, 1:40, 1:80, etc, with the 1 indicating 1 part blood and the second number indicating the parts of saline solution. A higher second number indicates a higher concentration of antinuclear antibodies in the blood.

Lab blood analysis to confirm blood unit compatibility by antiglobulin technique [HCPCS 86922]

Lab blood analysis to identify antigens on red blood cell surface and determine the patient's blood group type (ABO) [HCPCS 86900]

A blood specimen is tested to determine blood type (ABO) or Rh(D). Blood is grouped using an ABO blood typing system which identifies four blood types: type A, B, AB, or O. The blood sample is mixed with antibodies against Type A and B blood and then checked to determine if the blood cells agglutinate, or stick together. Type A blood has anti-B antibodies; type B blood has anti-A antibodies; type O blood has antibodies to both A and B; and type AB blood does not have anti-A or anti-B antibodies. Type A blood agglutinates when type B antibodies are introduced. Type B blood agglutinates when type A antibodies are introduced. Type O blood agglutinates when type A or B antibodies are introduced. Type AB blood does not agglutinate when type A or B antibodies are introduced. The blood is then back typed. Blood serum is mixed with blood that is known to be type A or B.

Drug administration beneath the skin or into muscle by injection for therapy, diagnosis, or prevention [HCPCS 96372]

A subcutaneous or intramuscular injection of a therapeutic, prophylactic, or diagnostic substance or drug is given. A subcutaneous injection is administered just under the skin in the fatty tissue of the abdomen, upper arm, upper leg, or buttocks. The skin is cleansed. A two-inch fold of skin is pinched between the thumb and forefinger. The needle is inserted completely under the skin at a 45 to 90 degree angle using a quick, sharp thrust. The plunger is retracted to check for blood. If blood is present, a new site is selected. If no blood is present, the medication is injected slowly into the tissue. The needle is withdrawn and mild pressure is applied. An intramuscular injection is administered in a similar fashion deep into muscle tissue, differing only in the sites of administration and the angle of needle insertion. Common sites include the gluteal muscles of the buttocks, the vastus lateralis muscle of the thigh, or the deltoid muscle of the upper arm. The angle of insertion is 90 degrees. Intramuscular administration provides rapid systemic absorption and can be used for administration of relatively large doses of medication.

Elec stim other than wound [HCPCS G0283]

Electrical stimulation (unattended), to one or more areas for indication(s) other than wound care, as part of a therapy plan of care

Electrical stimulation application to 1 or more areas (each 15 minutes) [HCPCS 97032]

Electrical stimulation involves the use of a transcutaneous electrical nerve stimulation device (TENS), functional electrical stimulation device (FES), or a neuromuscular electrical stimulation device (NMES). The physical therapist or other physical therapy aid places the electrodes of the selected device over the region to be stimulated. The electrical impulse is set to the desired strength and the control unit is turned on. Electrical impulses are transmitted to the skin. The electrical stimulation device causes the muscles to contract. The muscle contraction stimulates both muscle and nerve tissues to relieve pain and promote healing. Electrical stimulation may be provided as a supervised modality that does not require direct (one-on-one) patient contact or it may be provided under constant attendance with direct (one-on-one) patient contact.

Function improvement activities with one-on-one contact between patient and provider (each 15 minutes) [HCPCS 97530]

In a one-on-one physical therapy session, the provider instructs and assists the patient in therapeutic activities designed to address specific functional limitations. The therapeutic activities are specifically developed and modified for the patient. Dynamic/movement activities, also called kinetic activities, that are designed to improve functional performance such as lifting, bending, pushing, pulling, jumping and reaching are included in this service. For example, the patient may be given therapeutic activities to perform to improve the ability to sit, stand, and get out of bed after an injury without straining or risking reinjury. This code is reported for each 15 minutes of one-on-one therapeutic activity provided.

Occupational therapy evaluation (typically 30 minutes) [HCPCS 97165]

An occupational therapy evaluation or re-evaluation is performed. Occupational therapy assists the patient in developing or regaining skills that allow independent functioning and enhance health and personal well-being. A patient history is taken that includes an occupational profile and medical and therapy history with review of records as well as an extensive review of physical, cognitive, or psychosocial elements related to current performance of daily activities. The occupational therapist evaluates the patient's physical functioning, mental, and/or neurobehavioral impairment and performs tests to identify functional limitations or performance deficits. Physical functioning is evaluated, including an evaluation of any musculoskeletal conditions that may impair function. The ability to perform basic activities of daily living such as dressing, bathing, mobility, and other activities for living independently, such as shopping, cooking, driving, or accessing public transportation are all assessed. Barriers in the home, school, work, and community environments are identified. The need for adaptive equipment is assessed. The occupational therapist develops a treatment plan using clinical decision making from the patient analysis, assessment data, comorbidities, and possible treatment options. During a re-evaluation, an interim history is taken; the patient's response to treatment is evaluated; and the plan of care is revised based on the patient's response to treatment, functional and medical status, and any changes in condition or environment that affect future interventions or goals.

Physcial therapy exercise of walking training to 1 or more areas (each 15 minutes) [HCPCS 97116]

Gait training is a therapeutic procedure that observes and educates an individual in the manner of walking including the rhythm, cadence, step, stride, and speed. The objective of gait training is to strengthen muscles and joints, improve balance and posture, and develop muscle memory. As the lower extremities are retrained for repetitive motion, the body also benefits from the exercise with increased endurance, improved heart/lung function, and reduced or improved osteoporosis. Gait training is an appropriate therapeutic procedure following brain and/or spinal cord injury, stroke, fracture of the pelvis and/or lower extremity, joint injury or replacement of the knee, hip, or ankle, amputation, and for certain musculoskeletal and/or neurological diseases. A treadmill fitted with a safety harness is initially used to ensure safe walking. As the patient gains strength and balance, step training and stair climbing is added to the treatment modality.

Physical therapy evaluation (typically 20 minutes) [HCPCS 97161]

A physical therapy evaluation or re-evaluation is performed. The physical therapist takes a history of the current complaint including onset of symptoms, comorbidities, changes since the onset, treatment received for the symptoms or condition, medications prescribed for it, and any other medications the patient is taking. A physical examination of body systems is done to assess physical structure and function, any activities or movements that exacerbate the symptoms, limit activity, or restrict participation in movement, as well as anything that helps to relieve the symptoms. The evaluation may involve provocative maneuvers or positions that increase symptoms; tests for joint flexibility and muscle strength; assessments of general mobility, posture, and core strength; evaluation of muscle tone; and tests for restrictions of movement caused by myofascial disorders. Following the history and physical, the therapist determines the patient's clinical presentation characteristics, provides a detailed explanation of the condition, identifies physical therapy treatment options, and explains how often and how long physical therapy modalities should be applied. The physical therapist will then develop a plan of care with clinical decision making based on patient assessment and/or measurable functional outcome. The plan of care may include both physical therapy in the clinic and exercises or changes in the home environment. Upon re-evaluation, the established care plan is reviewed and an interim history is taken requiring the use of standardized tests and measures. The patient's response to treatment is evaluated and the plan of care is revised based on the patient's measurable response.

Physical therapy procedure to re-educate brain-to-nerve-to-muscle function (each 15 minutes) [HCPCS 97112]

Therapeutic procedures for neuromuscular reeducation are used to develop conscious control of a single muscle or muscle group and heighten the awareness of the body's position in space, especially the position of the extremities when sitting or standing. Neuromuscular reeducation is employed during the recovery or regeneration stage following severe injury or trauma, cerebral vascular accident, or systemic neurological disease. The goal of therapy is improved range of motion (ROM), balance, coordination, posture, and spatial awareness. Techniques may include proprioceptive neuromuscular facilitation which uses diagonal contract-relax patterns of skeletal muscles to stimulate receptors in the joints that communicate body position to the brain via motor and sensory nerves. Feldenkrais is a method which observes the patient's habitual movement patterns and teaches new patterns based on efficient active or passive repetitive conditioning. Additional techniques that may be useful for neuromuscular reeducation are Bobath concept, which promotes motor learning and efficient motor control, and biomechanical ankle platform system (BAPS) boards.

Physical therapy re-evaluation (typically 20 minutes) [HCPCS 97164]

A physical therapy evaluation or re-evaluation is performed.

Physical therapy techniques to 1 or more regions (each 15 minutes) [HCPCS 97140]

Manual therapies are skilled, specific, hands-on techniques usually performed by physical therapists, occupational therapists, chiropractors, osteopaths, and/or physiatrists to diagnose and treat soft tissue and joint problems. The goal of manual therapy is to modulate pain and induce relaxation, increase range of motion (ROM), facilitate movement, function, and stability, decrease inflammation, and improve muscle tone and extensibility. Tissue mobilization involves slow, controlled myofascial stretching using deep pressure to break up fibrous muscle tissue and/or connective tissue adhesions. Manipulation is a more forceful stretching of the myofascial tissue that takes the joint just beyond its restricted barrier. Manual lymphatic drainage is a type of light massage employed to reduce swelling by gentle movement of the skin in the direction of lymphatic flow. Manual traction involves the controlled counterforce of the therapist to induce asymptomatic strain by gently stretching muscle and/or connective tissue.

Speech sound production evaluation with evaluation of language comprehension and expression [HCPCS 92523]

Disorders of speech sound production that relate to language comprehension and expression usually manifest before the age of 4 years. Mixed language disorder (receptive and expressive) may be due to brain injury, developmental problems such as autistic spectrum disorders, hearing loss and learning disorders. In receptive language disorders an individual will have problems understanding what has been said, following directions and organizing thoughts. Expressive language disorders can manifest with difficulty putting words together to form coherent sentences, word finding and the use of placeholder words such as ôumö, decreased vocabulary for age, leaving out words when speaking, improper use of tenses (past, present, future) and repetition (echoing) of phrases. Evaluation by a speech-language pathologist (SLP) should include an audiogram to assess hearing (reported separately), formal and informal observation and assessment using standardized testing tools such as Receptive-Expressive Emergent Language Test (REEL).

Speech, language, voice, communication, and/or hearing processing disorder treatment [HCPCS 92507]

A speech-language pathologist treats a speech, language, voice, communication, and/or auditory processing disorder. Using the information obtained from a separately reportable screening and in-depth evaluation of a speech or language disorder, the clinician develops an individualized treatment plan for the patient. The clinician defines specific treatment goals and sets baseline measures with which to assess the patient's progress. These goals are continuously monitored and fine-tuned throughout the treatment period. Once the goals and baseline measures have been established the clinician uses a number of intervention activities to correct the specific speech or language disorder identified. These can include games, stories, rhymes, drills, and other tasks. If the patient has a speech disorder, the clinician may demonstrate the sounds and have the patient copy the way the clinician moves the lips, mouth, and tongue to make the right sound. A mirror may be used so that the patient can practice making the sound while observing himself or herself in the mirror. Treatment of a language disorder might include help with grammar. If the patient is having difficulty with auditory processing, a game like Simon Says might be used to help improve understanding of verbal instructions.

Swallowing and/or oral feeding function treatment [HCPCS 92526]

Swallowing dysfunction and/or oral function are treated in an individual with difficulty passing food or liquid from the mouth or throat into the stomach. A swallowing or oral function disorder can occur in any age group or at any point in the swallowing process as food or liquid passes from the mouth, through the pharynx and esophagus, into the stomach. Swallowing disorders are common in individuals with degenerative neurological disorders such as cerebral palsy, amyotrophic lateral sclerosis (ALS), postpolio syndrome, myasthenia gravis, multiple sclerosis, and Parkinson's disease. A swallowing disorder may also result from neurological damage such as a stroke or head or spinal cord injury, or from a congenital or acquired deformity of the mouth, pharynx, esophagus, or stomach. Medical treatment is provided for a patient with a swallowing or oral function disorder. The diet is modified. Swallowing posture is assessed and modified as needed. Swallowing technique is modified to strengthen oropharyngeal muscle groups and improve the mechanics of swallowing so that food and liquid can pass into the esophagus and then into the stomach without aspiration into the lungs.

Swallowing function evaluation [HCPCS 92610]

An evaluation of the oral and pharyngeal phase of the swallowing function is performed in a patient who is suspected of having oropharyngeal dysphagia. The initial evaluation is typically performed by a dysphagia specialist, usually a speech-language pathologist. This evaluation is performed to determine whether more extensive studies are warranted. Swallowing function is divided into oral, pharyngeal, and esophageal phases. The oral and pharyngeal phases are made up of oral preparation for solid foods (not required for liquids or pureed foods), oral transfer, and initiation of the swallow. Both oral and pharyngeal movements are necessary in preparing, transferring, and swallowing food. The patient is given both solids and liquids to swallow. During oral preparation of solid food the ability of the tongue to move the food from side-to-side so that the solid can be chewed and prepared for swallowing is evaluated. Once the solid food is prepared and transferred to the back of the throat, the swallowing movements are evaluated. Propelling solids or liquids requires a complex set of movements including retraction of the base of the tongue, elevation of the hyolarynx, closure of the velopharyngeus, contraction of the pharynx, opening of the upper esophageal sphincter, and closure of the airway. The speech-language pathologist observes the patient to determine whether solids and liquids are being prepared, transferred, and propelled from the pharynx into the esophagus. A written report of findings is provided.

Training activities for home and self-care management (each 15 minutes) [HCPCS 97535]

Self-care/home managemeThe patient receives one-on-one training to improve the ability to care for himself/herself and maintain independence. This may include training in activities of daily living (ADL), such as bed mobility, transfers, dressing, grooming, eating, bathing and toileting. The patient is given instruction on compensatory measures that can be taken to overcome any physical, mental or emotional disabilities. The patient receives training in how to adapt meal preparation to his/her specific needs and how to perform activities safely. The patient may also receive instruction in the use of assistive technology devices and adaptive equipment which includes any item used to improve the functional capability of the patient in the home and with ADL. This code is reported for each 15 minutes of one-on-one self-care/home management training designed to meet the specific needs of the patient.nt training, which includes instructions in the use of any assisting equipment.

Pulmonary rehab w exer [HCPCS G0424]

Lung diffusing capacity measurement [HCPCS 94729]

The diffusing capacity of the lungs using carbon monoxide (CO) measures the ability of the lungs to transfer gas from inhaled air across the alveolar-capillary membrane to the red blood cells. This test is performed in conjunction with other separately reportable pulmonary function tests to determine whether lung restriction is due to parenchymal (intrapulmonary, interstitial) disease or to decreased cardiac output (extrapulmonary). The patient breathes all the way out. The patient then breathes in through the mouthpiece of the diffusion capacity testing device which delivers a gas mixture containing 0.3 percent CO, 10 percent Helium, 21 percent oxygen and 68.7 percent nitrogen. When total lung capacity is reached, the patient holds his/her breath for 10 seconds. The patient then breathes out, expelling the gas that has been in the dead space (mouth, trachea, and two main bronchi), which is discarded. The remainder of the gas is exhaled and collected. The amount of the various exhaled gases in the sample is then analyzed and diffusing capacity is evaluated. The physician reviews the test results and provides a written report of findings.

Blood sample collection by skin puncture [HCPCS 36416]

Large joint or joint capsule fluid removal and/or injection with needle [HCPCS 20610]

Arthrocentesis, aspiration, and/or injection of a joint or bursa is performed. Arthrocentesis and aspiration is performed to remove fluid from a joint or bursa in order to diagnose the cause of joint effusion and/or to reduce pain caused by the excess fluid. Injection of a joint or bursa may be performed in conjunction with the arthrocentesis procedure and is typically performed using an anti-inflammatory medication such as a steroid to reduce inflammation of the joint or bursa. The skin over the joint is cleansed. A local anesthetic is injected as needed. A needle with a syringe attached is inserted into the affected joint or bursa. Fluid is removed and sent for separately reportable laboratory analysis. This may be followed by a separate injection of medication into the joint or bursa.

Needle insertion into vein for collection of blood sample [HCPCS 36415]

An appropriate vein is selected, usually one of the larger anecubital veins such as the median cubital, basilic, or cehalic veins. A tourniquet is placed above the planned puncture site. The site is disinfected with an alcohol pad. A needle is attached to a hub and the vein is punctured. A Vacuainer tube is attached to the hub and the blood specimen is collected. The Vacutainer tube is removed. Depending on the specific blood tests required, multiple Vacutainers may be filled from the same punchture site.

Abdominal and pelvic CT scan without contrast for injury, foreign bodies, or tumors [HCPCS 74176]

Computerized tomography, also referred to as a CT scan, uses special x-ray equipment and computer technology to produce multiple cross-sectional images of the abdomen and pelvis. The patient is positioned on the CT examination table. An initial pass is made through the CT scanner to determine the starting position of the scans. The CT scan is then performed. As the table moves slowly through the scanner, numerous x-ray beams and electronic x-ray detectors rotate around the abdomen and pelvis. The amount of radiation being absorbed is measured. As the beams and detectors rotate around the body, the table is moved through the scanner. A computer program processes the data which is then displayed on the monitor as two-dimensional cross-sectional images of the abdomen or pelvis. The physician reviews the data and images as they are obtained and may request additional sections to provide more detail on areas of interest.

Abdominal ultrasound (limited) [HCPCS 76705]

A real time abdominal ultrasound is performed with image documentation. The patient is placed supine. Acoustic coupling gel is applied to the skin of the abdomen. The transducer is pressed firmly against the skin and swept back and forth over the abdomen and images obtained. The ultrasonic wave pulses directed at the abdomen are imaged by recording the ultrasound echoes. Any abnormalities are evaluated to identify characteristics that might provide a definitive diagnosis. The physician reviews the ultrasound images of the abdomen and provides a written interpretation.

Abdominal x-ray (2 views) [HCPCS 74019]

A radiologic examination of the abdomen images the internal organs, soft tissue (muscle, fat), and supporting skeleton. X-ray imaging uses indirect ionizing radiation to take pictures of non-uniform material, such as human tissue, because of its different density and composition, which allows some of the x-rays to be absorbed and some to pass through and be captured. This produces a 2D image of the structures. The radiographs may be taken to look for size, shape, and position of organs, pattern of air (bowel gas), obstruction, foreign objects, and calcification in the gallbladder, urinary tract, and aorta. A radiologic examination of the abdomen may be ordered to diagnose abdominal distention and pain, vomiting, diarrhea or constipation, and traumatic injury; it may also be obtained as a screening exam or scout film prior to other imagining procedures. Common views of the abdomen include front to back anteroposterior (AP) with the patient lying supine or standing erect, back to front posteroanterior (PA) with the patient lying prone, lateral with the patient lying on the side, lateral decubitus anteroposterior (side lying, front to back view), lateral dorsal decubitus (lying supine, side view), oblique (anterior or posterior rotation), and coned (small collimated) views which may be used to localize and differentiate lesions, calcifications, or herniations.

Ankle x-ray (2 views) [HCPCS 73600]

A radiologic examination of the ankle images the bones of the distal lower extremities including the tibia, fibula, and talus. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for the cause of pain, limping, or swelling, or conditions such as fractures, dislocations, deformities, degenerative disease, osteomyelitis, arthritis, foreign body, and cysts or tumors. Ankle x-rays may also be used to determine whether there is satisfactory alignment of lower extremity bones following fracture treatment. Standard views of the ankle include front to back anteroposterior (AP), lateral (side), oblique (semi-prone position with body and leg partially rotated), and stress study with traction placed on the joint manually.

Ankle x-ray (minimum of 3 views) [HCPCS 73610]

Arm or leg ultrasound (complete) [HCPCS 76881]

Ultrasound, also referred to as sonography and echography, is a non-invasive imaging technique that uses high-frequency sound waves to evaluate tissues and structures. Nonvascular structures of the extremities that may be evaluated by ultrasound include periarticular soft tissue masses, muscles, tendons, nerves, ligaments, and joints. Common conditions that can be detected or evaluated by ultrasound include cystic lesions, solid tumors, abscesses, joint effusion, tendon tears, tendonitis, tenosynovitis, nerve compression, and stress fractures. Acoustic coupling gel is applied to the extremity to be examined. An ultrasound probe is placed against the skin and moved over the target joint area to be examined as sound waves pass through and bounce off extremity tissues and structures. The sound waves are reflected back to the receiving unit at varying speeds and converted into images. Longitudinal, transverse, and oblique images are obtained. The physician reviews the images and provides a written interpretation.

Arm x-ray of forearm (2 views) [HCPCS 73090]

A radiologic examination of the forearm is done. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. Frontal views, or back to front (PA) views and lateral views are necessary to show the radius and ulna and assess the extent and direction of injury. Since the radius and ulna are anatomically connected at both ends of the bones with ligaments, the two bones function in a manner that makes the forearm considered as a single unit when assessing injury. The two standard views taken for x-ray examination of the forearm include the anteroposterior (AP) view, and the lateral view.

Arm x-ray of upper arm (minimum of 2 views) [HCPCS 73060]

A radiologic examination of the humerus is done with a minimum of 2 views taken. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The surgical neck of the humerus is the most common site of fracture. Shaft fractures are often associated with some kind of pathological lesion. X-rays of the humerus can be taken to detect deformities or lesions in the upper arm, such as cysts, tumors, late stage infection, or other diseases as well as a broken bone. The standard views of the humerus include the front to back anteroposterior view and the side, or lateral view.

Arms or legs veins ultrasound with assessment of compression and functional maneuvers (complete, both arms or legs) [HCPCS 93970]

A vascular ultrasound study is performed to evaluate veins in the extremities. A duplex scan uses both B-mode and Doppler studies. A clear gel is placed on the skin of the extremity over the region to be studied. A B-mode transducer is placed on the skin and real-time images of the veins are obtained. A Doppler probe within the B-mode transducer provides information on the pattern and direction of blood flow in the veins. The B-mode transducer produces ultrasonic sound waves that move through the skin and bounce off the veins when the probe is moved over the region being studied. The Doppler probe produces sound waves that bounce off blood cells moving within the veins. The reflected sound waves are sent to an amplifier that makes the sound waves audible. The pitch of the sound waves changes if there is reduced blood flow, or ceases altogether if a vessel is completely obstructed. A computer converts the sound waves to images that are overlaid with colors to produce video images showing the speed and direction of blood flow as well as any obstruction. Spectral Doppler analysis is performed to provide information on anatomy and hemodynamic function. The duplex scan may include a baseline evaluation followed by additional scans obtained with compression or using other maneuvers that alter blood flow. The physician reviews the duplex scan and provides a written interpretation of findings.

Blood flow (outside of the brain) ultrasound on both sides of head and neck [HCPCS 93880]

A vascular ultrasound study is performed to evaluate the extracranial arteries which include the common carotid and external carotid arteries. A duplex scan uses both B-mode and Doppler studies. A clear gel is placed on the skin over the arteries to be studied. A B-mode transducer is placed on the skin and real-time images of the artery are obtained. A Doppler probe within the B-mode transducer provides information on pattern and direction of blood flow in the artery. The B-mode transducer produces ultrasonic sound waves that move through the skin and bounce off the arteries when the probe is placed over the arteries at various locations and angles. The Doppler probe produces sound waves that bounce off blood cells moving within the artery. The reflected sound waves are sent to an amplifier that makes the sound waves audible. The pitch of the sound waves changes if there is reduced blood flow, or ceases altogether if a vessel is completely obstructed. A computer converts the sound waves to images that are overlaid with colors to produce video images showing the speed and direction of blood flow as well as any obstruction. Spectral Doppler analysis is performed to provide information on anatomy and hemodynamic function, including information on the presence of narrowing and plaque formation within the arteries. The physician reviews the duplex scan and provides a written interpretation of findings.

Bone density measurement of the axial skeleton (hips, pelvis, spine) [HCPCS 77080]

These codes report dual-energy x-ray absorptiometry (DXA) for bone density study. Measuring bone mass or bone mineral density (BMD) is done to diagnose for bone disease, evaluate bone disease progression, or monitor the results of treatment, particularly for osteoporosis, which puts a bone at higher risk of fracture. The radiation dose of DXA is around 1/30th of that in a standard chest x-ray. DXA involves aiming two x-ray beams of different energy levels at the bones in alternate pulses. Soft tissue absorption is subtracted out, and the BMD is determined by the bone's absorption of each beam in the projected area. The DXA scan measurement is then compared to a same sex standard of bone density at age 30, since the maximum BMD occurs at age 30 in both males and females. The difference between the measured BMD and the sex-matched, average 30-year-old standard is known as the T score. A T score between -1.0 and -2.4 diagnoses osteopenia, while a T score of -2.5 or less indicates osteoporosis.

Breast ultrasound (one breast, complete) [HCPCS 76641]

A real time ultrasound of the right or left breast is performed with image documentation, including the axillary area, when performed. Breast ultrasound is used to help diagnose breast abnormalities detected during a physical exam or on mammography. Ultrasound imaging can identify masses as solid or fluid-filled and can show additional structural features of the abnormal area and surrounding tissues. The patient is placed supine with the arm raised above the head on the side being examined. Acoustic coupling gel is applied to the breast and the transducer is pressed firmly against the skin of the breast. The transducer is then swept back and forth over the area of the abnormality and images are obtained. The ultrasonic wave pulses directed at the breast are imaged by recording the ultrasound echoes. Any abnormalities are evaluated to identify characteristics that might provide a definitive diagnosis. The physician reviews the ultrasound images of the breast and provides a written interpretation.

Chest CT scan with contrast to examine injury, foreign bodies, or tumors [HCPCS 71260]

Diagnostic computed tomography (CT) is done on the thorax. CT uses multiple, narrow x-ray beams aimed around a single rotational axis, taking a series of 2D images of the target structure from multiple angles. Contrast material is used to enhance the images. Computer software processes the data and reconstructs a 3D image. Thin, cross-sectional 2D and 3D slices are then produced of the targeted organ or area. The patient is placed inside the CT scanner on the table and images are obtained of the thorax to look for problems or disease in the lungs, heart, esophagus, soft tissue, or major blood vessels of the chest, such as the aorta. The physician reviews the images to look for suspected disease such as infection, lung cancer, pulmonary embolism, aneurysms, and metastatic cancer to the chest from other areas.

Chest x-ray (2 views) [HCPCS 71046]

A radiologic examination of the chest is performed. Chest radiographs (X-rays) provide images of the heart, lungs, bronchi, major blood vessels (aorta, vena cava, pulmonary vessels), and bones, (sternum, ribs, clavicle, scapula, spine). The most common views are frontal (also referred to as anteroposterior or AP), posteroanterior (PA), and lateral. To obtain a frontal view, the patient is positioned facing the x-ray machine. A PA view is obtained with the patient's back toward the x-ray machine. For a lateral view, the patient is positioned with side of the chest toward the machine. Other views that may be obtained include apical lordotic, oblique, and lateral decubitus. An apical lordotic image provides better visualization of the apical (top) regions of the lungs. The patient is positioned with the back arched so that the tops of the lungs can be x-rayed. Oblique views may be obtained to evaluate a pulmonary or mediastinal mass or opacity or to provide additional images of the heart and great vessels. There are four positions used for oblique views including right and left anterior oblique, and right and left posterior oblique. Anterior oblique views are obtained with the patient standing and the chest rotated 45 degrees. The arm closest to the x-ray cassette is flexed with the hand resting on the hip. The opposite arm is raised as high as possible. The part of the chest farthest away from the x-ray cassette is the area being studied. Posterior oblique views are typically obtained only when the patient is too ill to stand or lay prone for anterior oblique views. A lateral decubitus view is obtained with the patient lying on the side; the patient's head rests on one arm, and the other arm is raised over the head with the elbow bent. Images are recorded on hard copy film or stored electronically as digital images. The physician reviews the images, notes any abnormalities, and provides a written interpretation of the findings.

Collar bone x-ray, complete study [HCPCS 73000]

A complete radiologic examination of the clavicle is performed to determine fractures or dislocations. The most common type of fracture involves the middle third of the clavicle, followed by the lateral third distal to the coracoclavicular ligament. The least common type of clavicular fracture involves the proximal third. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. Radiographs are taken according to the suspected location of the injury. Standard evaluation includes an anteroposterior view focused on the midshaft wide enough to assess the acromioclavicular and sternoclavicular joints. Oblique views are also obtained with a cephalic tilt of 20-60 degrees.

CTA scan of neck blood vessels with contrast to examine blood clots or aneurysms [HCPCS 70498]

A computed tomographic angiography (CTA) of the neck is performed with contrast material including image postprocessing. Noncontrast images may also be obtained and are included when performed. CTA provides images of the blood vessels using a combination of computed tomography (CT) and angiography with contrast material. When angiography is performed using CT, multiple images are obtained and processed on a computer to create detailed, two-dimensional, cross-sectional views of the blood vessels. These images are then displayed on a computer monitor. The patient is positioned on the CT table. An intravenous line is inserted into a blood vessel, usually in the arm or hand. Non-contrast images may be obtained. A small dose of contrast is injected and test images are obtained to verify correct positioning. The CTA is then performed. Contrast is injected at a controlled rate and the CT table moves through the CT machine as the scanning is performed. After completion of the CTA, the radiologist reviews and interprets the CTA images of the neck.

Elbow x-ray, complete study (minimum of 3 views) [HCPCS 73080]

A radiologic examination of the elbow is done. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. X-rays of the elbow are usually considered necessary to assess for fractures or dislocations when the normal range of motion for extension, flexion, supination, and pronation cannot be carried out. Most acute disruptions of the elbow joint can be diagnosed by conventional x-ray examination, with the minimum number of views including the front to back anteroposterior projection with the elbow in as full extension as possible, and the side, or lateral image taken in flexion. A complete series of images also includes an oblique view of the radial head-capitellar image to help diagnose suspected subtle fractures involving the radial head or in cases of acute pain and trauma. The patient needs to be able to hold the elbow in full extension for the front view and in 90 degree flexion for the oblique and lateral views as much as possible.

Facial CT scan without contrast to examine injury, foreign bodies, or tumors [HCPCS 70486]

Computerized tomography, also referred to as a CT scan, uses special x-ray equipment and computer technology to produce multiple cross-sectional images of the region being studied. In this study, CT scan of the maxillofacial area is obtained. The maxillofacial area includes the forehead (frontal bone), sinuses, nose and nasal bones, jaw (maxilla and mandible). The only facial region not included in this study is the orbit. The patient is positioned on the CT examination table. An initial pass is made through the CT scanner to determine the starting position of the scans, after which the CT scan is performed. As the table moves slowly through the scanner, numerous x-ray beams and electronic x-ray detectors rotate around the body region being examined. The amount of radiation being absorbed is measured. As the beams and detectors rotate around the body, the table is moved through the scanner. A computer program processes the data and renders the data in two-dimensional cross-sectional images of the body region being examined. This data is displayed on a monitor. The physician reviews the data as it is being obtained and may request additional sections to provide more detail of areas of interest.

Finger(s) x-ray (minimum of 2 views) [HCPCS 73140]

A radiologic examination of the finger(s) is done with at least 2 different projections taken. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for conditions such as fractures, interphalangeal (IP) joint dislocations, deformities, degenerative bone conditions, osteomyelitis, arthritis, foreign body, or tumors. The posteroanterior projection is taken with the palm down flat, fingers extended, and slightly apart to show the metacarpals, phalanges, and IP joints of the target finger(s). Anteroposterior views are taken with the back of the hand placed on the film and the x-ray beam going from palmar to dorsal direction. Lateral views are taken with the ulnar side of the hand on the film cassette and the fingers spread apart to avoid overlap, sometimes supported from underneath. Oblique views can be obtained with the hand placed palm down and the radial side rotated 45 degrees up away from the surface, with the fingers extended and spread apart.

Foot x-ray (2 views) [HCPCS 73620]

A radiologic examination of the foot images the bones of the distal lower extremity and may include the tibia, fibula, talus, calcaneus, cuboid, navicular, cuneiform, metatarsals, and phalanges. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for the cause of pain, limping, or swelling, or conditions such as fractures, dislocations, deformities, degenerative disease, osteomyelitis, arthritis, foreign body, and cysts or tumors. Foot x-rays may also be used to determine whether there is satisfactory alignment of foot bones following fracture treatment. Standard views of the foot include top to bottom dorsal planter (DP), lateral (side), oblique (semi-prone position with body and leg partially rotated), and stress study with traction placed on the joint manually.

Foot x-ray at heel of foot (minimum of 2 views) [HCPCS 73650]

A radiologic examination of the calcaneus images the bones of the distal lower extremity and usually includes the tibia, fibula, and talus.

Calcaneus and toe(s) x-rays may also be used to determine whether there is satisfactory alignment of lower extremity bones following fracture treatment. Standard views to image the calcaneus include lateral (side) and axial (supine with foot dorsiflexed). Common views to image the toe(s) include top to bottom dorsal planter (DP) and oblique (supine with leg rotated medially to image the 1st, 2nd, and 3rd digits and laterally to image the 4th and 5th digits).

X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for conditions such as fractures, dislocations, deformities, degenerative bone conditions, osteomyelitis, arthritis, foreign body, or tumors. Hand x-rays are also used to help determine the 'bone age' of children and assess whether any nutritional or metabolic disorders may be interfering with proper development. The posteroanterior projection is taken with the palm down flat and may show not only the metacarpals, phalanges, and interphalangeal joints, but the carpal bones, radius, and ulna as well. Lateral views may be taken with the hand placed upright, resting upon the ulnar side of the palm and little finger with the thumb on top, ideally with the fingers supported by a sponge and splayed to avoid overlap. Oblique views can be obtained with the hand placed palm down and rolled slightly to the outside with the fingertips still touching the film surface. The beam is angled perpendicular to the cassette for oblique projections and aimed at the middle finger metacarpophalangeal joint.

Head and neck ultrasound [HCPCS 76536]

An ultrasound examination of soft tissues of the head and neck is performed with image documentation. The thyroid, parathyroid, or parotid glands and surrounding soft tissue may be examined. Ultrasound visualizes the body internally using sound waves far above human perception bounce off interior anatomical structures. As the sound waves pass through different densities of tissue, they are reflected back to the receiving unit at varying speeds and converted into pictures displayed on screen. A linear scanner or mechanical sector scanner is used to evaluate the shape, size, border, internal architecture, distal enhancement, color flow, and echogenicity of the soft tissue structures of the head and neck as well as any lesions or masses. The echogenicity is compared to that of the surrounding muscle tissue. The physician reviews the images and provides a written interpretation.

Head or brain CT scan without contrast, followed by contrast to examine injury, foreign bodies, or tumors [HCPCS 70470]

Computerized tomography, also referred to as a CT scan, uses special x-ray equipment and computer technology to produce multiple cross-sectional images of the region being studied. In this study, CT scan of the head or brain is performed. The patient is positioned on the CT examination table. An initial pass is made through the CT scanner to determine the starting position of the scans after which the CT scan is performed. As the table moves slowly through the scanner, numerous x-ray beams and electronic x-ray detectors rotate around the body region being examined. The amount of radiation being absorbed is measured. As the beams and detectors rotate around the body, the table is moved through the scanner. A computer program processes the data and renders the data in two-dimensional cross-sectional images of the body region being examined. This data is displayed on a monitor. The physician reviews the data as it is being obtained and may request additional sections to provide more detail of areas of interest.

Heart ultrasound including color-depicted blood flow rate, direction, and valve function [HCPCS 93306]

The physician performs complete transthoracic real-time echocardiography with image documentation (2-D) including M-mode recording, if performed, with spectral Doppler and color flow Doppler echocardiography. Cardiac structure and dynamics are evaluated using a series of real-time tomographic images with multiple views recorded digitally or on videotape. Time-motion (M-mode) recordings are made as needed to allow dimensional measurement. Blood flow and velocity patterns within the heart, across valves and within the great vessels are evaluated by color flow Doppler. Normal blood flow patterns through these regions have a characteristic pattern defined by direction, velocity, duration, and timing throughout the cardiac cycle. Spectral Doppler by pulsed or continuous wave technique is used to evaluate antegrade flow through inflow and outflow tracts and cardiac valves. Multiple transducer positions or orientations may be required. The physician reviews the echocardiography images and orders additional images as needed to allow evaluation of any abnormalities. Digital or videotaped images are then reviewed by the physician. Abnormalities of cardiac structure or dynamics are noted. The extent of the abnormalities is evaluated and quantified. Any previous cardiac studies are compared to the current study and any quantitative or qualitative changes are identified. The physician provides an interpretation of the echocardiography with a written report of findings.

Hip x-ray of both hips with pelvis (3 to 4 views) [HCPCS 73522]

A radiologic examination is done on both the left and the right hip, which may also include the pelvis. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for conditions such as fractures, dislocations, deformities, degenerative bone conditions, osteomyelitis, arthritis, foreign body, infection, or tumor. Hip standard views that are taken most frequently include the front to back anteroposterior view taken with the patient lying supine and the legs straight, rotated slightly inward; the lateral ‘frog-leg’ view, taken with the hips flexed and abducted and the knees flexed with the soles of the feet placed together; a cross table view with the unaffected hip and knee flexed at a 90 degree angle out of the way and the beam aimed perpendicular to the long axis of the femur on the affected side. Another type of lateral view is taken with the hip flexed 45 degrees and abducted 45 degrees and the beam aimed perpendicular to the table. A front to back view of the hips in a pelvic view is often taken with the patient supine and both legs rotated slightly inward about 15 degrees.

Hip x-ray of hip with pelvis (2 to 3 views) [HCPCS 73502]

A radiologic examination of the hip is done on either the left or the right side, which may also include the pelvis. X-ray imaging uses indirect ionizing radiation to take pictures inside the body.

Another type of lateral view is taken with the hip flexed 45 degrees and abducted 45 degrees and the beam aimed perpendicular to the table.

Jaw joint x-ray in two presentations, open and closed (both sides of mouth) [HCPCS 70330]

Knee x-ray (1 or 2 views) [HCPCS 73560]

A radiologic examination of the knee images the femur, tibia, fibula, patella, and soft tissue. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for the cause of pain, limping, or swelling, or conditions such as fractures, dislocations, deformities, degenerative disease, osteomyelitis, arthritis, foreign body, and cysts or tumors. Knee x-rays may also be used to determine whether there is satisfactory alignment of lower extremity bones following fracture treatment. Standard views of the knee include front to back anteroposterior (AP), lateral (side), and back to front posteroanterior (PA) with variations in the flexion of the joint, and weight bearing and non-weight bearing postures.

Leg CT scan without contrast for injury, foreign bodies, or tumors [HCPCS 73700]

Diagnostic computed tomography (CT) is done on the lower extremity to provide detailed visualization of the tissues and bone structure of the leg. CT uses multiple, narrow x-ray beams aimed around a single rotational axis, taking a series of 2D images of the target structure from multiple angles. Contrast material is used to enhance the images. Computer software processes the data and produces several images of thin, cross-sectional 2D slices of the targeted organ or area. Three-dimensional models of the leg can be created by stacking multiple, individual 2D slices together. The patient is placed inside the CT scanner on the table and images are obtained of the lower extremity.

Lower leg x-ray (2 views) [HCPCS 73590]

A radiologic examination of the tibia and fibula images the bones of the distal lower extremities and may include the knee and ankle joints. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector.

The radiographs may be taken to look for the cause of pain, limping, or swelling, or conditions such as fractures, dislocations, deformities, degenerative disease, osteomyelitis, arthritis, foreign body, and cysts or tumors. Tibia and fibula x-rays may also be used to determine whether there is satisfactory alignment of lower extremity bones following fracture treatment. Standard views of the tibia and fibula include front to back anteroposterior (AP) and lateral (side).

Neck CT scan of the soft tissue of the neck with contrast to examine injury, foreign bodies, or tumors [HCPCS 70491]

Computerized tomography, also referred to as a CT scan, uses special x-ray equipment and computer technology to produce multiple cross-sectional images of the region being studied. In a CT scan of the soft tissues of the neck, the patient is positioned on the CT examination table. An initial pass is made through the CT scanner to determine the starting position of the scans, after which the CT scan is performed. As the table moves slowly through the scanner, numerous x-ray beams and electronic x-ray detectors rotate around the body region being examined. The amount of radiation being absorbed is measured. As the beams and detectors rotate around the body, the table is moved through the scanner. A computer program processes the data and renders the data in two-dimensional cross-sectional images of the body region being examined. This data is displayed on a monitor. The physician reviews the data as it is being obtained and may request additional sections to provide more detail of areas of interest.

Neck x-ray to examine soft tissue for any obstructions and/or foreign bodies within the throat or neck [HCPCS 70360]

X-rays are taken to evaluate the soft tissue of the neck. X-ray uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. Frontal and lateral views of the neck may be taken for better evaluation. The physician reviews the radiographs to determine any asymmetry or enlargement on one side or the other, the caliber and contour of the trachea, and any soft tissue swelling that may involve the adenoids, tonsils, epiglottis, or aryepiglottic folds.

Pelvis CT scan without contrast to examine injury, foreign bodies, or tumors [HCPCS 72192]

Diagnostic computed tomography (CT) is done on the pelvis to provide detailed visualization of the organs and structures within or near the pelvis, such as kidneys, bladder, prostate, uterus, cervix, vagina, lymph nodes, and pelvic bones. CT uses multiple, narrow x-ray beams aimed around a single rotational axis, taking a series of 2D images of the target structure from multiple angles. Contrast material is used to enhance the images. Computer software processes the data and produces several images of thin, cross-sectional 2D slices of the targeted organ or area. Three-dimensional models of organs within the pelvis can be created by stacking multiple, individual 2D slices together. The patient is placed inside the CT scanner on the table and images are obtained of the pelvis area. The physician reviews the images to gather information for specified purposes such as diagnosing or monitoring cancer, evaluating the pelvic bones for fractures or other injury following trauma, locating abscesses or masses found during physical exam, finding the cause of pelvic pain, providing more detailed information before surgery, and evaluating the patient after surgery.

Pelvis ultrasound, not pregrnancy related (complete) [HCPCS 76856]

A real time pelvic (non-obstetric) ultrasound is performed with image documentation to evaluate the uterus and cervix, ovaries, fallopian tubes, and bladder. Conditions evaluated include pelvic pain, abnormal bleeding, and palpable masses, such as ovarian cysts, uterine fibroids, or other pelvic masses. The patient presents with a full bladder. Acoustic coupling gel is applied to the skin of the lower abdomen. The transducer is pressed firmly against the skin and swept back and forth over the lower abdomen and images obtained of the uterus, ovaries, and surrounding pelvic structures. The ultrasonic wave pulses directed at the pelvic structures are imaged by recording the ultrasound echoes. Any abnormalities are evaluated. The physician reviews the ultrasound images and provides a written interpretation.

Pelvis x-ray (1 or 2 views) [HCPCS 72170]

A diagnostic x-ray examination of the pelvis is done. X-ray uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. Bones appear white while soft tissue and fluids appear shades of grey. Pelvic x-rays are taken when the patient complains of pain and/or injury in the area of the pelvis or hip joints to assess for fractures and detect arthritis or bone disease. The patient is placed on a table and different views of the pelvis are taken by having the patient position the legs and feet differently, such as turning the feet inward to point at each other, or bending the knees outward with the soles of the feet together in a 'frog-leg' position.

Rib cage x-ray of ribs on both sides of body including chest (minimum of 4 views) [HCPCS 71111]

Rib radiographs (x-rays) are typically obtained following trauma to the rib cage to determine if fractures or other internal injuries are present. The most common views of the ribs are anteroposterior (AP) (frontal) and oblique. There are four positions used for oblique views: right anterior oblique, left anterior oblique, right posterior oblique, and left posterior oblique. Anterior oblique views are obtained with the patient standing and the chest rotated 45 degrees. The arm closest to the x-ray cassette is flexed with the hand resting on the hip. The opposite arm is raised as high as possible. The part of the chest farthest away from the x-ray cassette is the area that is being studied. Posterior oblique views are typically obtained only when the patient is too ill to stand or lay prone for anterior oblique views.

Rib cage x-ray of ribs on one side of body (2 views) [HCPCS 71100]

Rib radiographs (x-rays) are typically obtained following trauma to the rib cage to determine if fractures or other internal injuries are present.

The opposite arm is raised as high as possible. The part of the chest farthest away from the x-ray cassette is the area that is being studied. Posterior oblique views are typically obtained only when the patient is too ill to stand or lay prone for anterior oblique views.

Shoulder blade x-ray complete study [HCPCS 73010]

A complete radiologic examination of the scapula is performed. Fractures of the scapula are not very common and are sometimes found even when there is no clinical suspicion of injury. Parts of the scapula include the body, acromion, spine, coracoid, neck, and glenoid. The acromion and the coracoid form a 'Y' shape where they join with the body of the scapula. The lateral scapula view, also called the 'Y' view, is the standard view that may be taken by different techniques for a complete examination, including the anteroposterior (AP) or posteroanterior (PA) technique views, further dependent on arm position. With the patient in an oblique AP or PA position, lateral views may be taken with the hand on the hip, the arm by the side, and the hand of the target side placed on the opposite shoulder. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures.

Shoulder x-ray, complete study (minimum of 2 views) [HCPCS 73030]

A radiologic examination of the shoulder is done. The shoulder is the junction of the humeral head and the glenoid of the scapula. Standard views include the anteroposterior (AP) view and the lateral 'Y' view, named because of the Y shape formed by the scapula when looking at it from the side. An axial view can also be obtained for further assessment when the patient is able to hold the arm in abduction. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures.

Spinal x-ray of lower and sacral spine (2 or 3 views) [HCPCS 72100]

A radiologic exam is done of the lumbosacral spine. Frontal, posteroanterior, and lateral views are the most common projections taken. X-ray uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures.

Spinal x-ray of middle spine (3 views) [HCPCS 72072]

Thighbone x-ray (minimum of 2 views) [HCPCS 73552]

A radiologic examination of the femur is done between the hip and the knee. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for the cause of pain, limping, or swelling, conditions such as fractures, dislocations, deformities, degenerative bone conditions, osteomyelitis, arthritis, foreign body, and cysts or tumors. X-rays may also be used to determine whether the femur is in satisfactory alignment following fracture treatment. Femur standard views that are taken most frequently include the front to back anteroposterior view and the lateral view from the side.

Ultrasound application to 1 or more areas (each 15 minutes) [HCPCS 97035]

Ultrasound uses high frequency sound waves applied to produce heat and/or vibration to promote the circulation, reduce inflammation, and improve the flexibility of connective tissue. A water-soluble gel is applied to the site to be treated. A hand-held device is used to deliver the sound waves. The device is moved over the site using a circular motion. Ultrasound is helpful in treating acute soft tissue injures. Ultrasound is a physical therapy modality that requires constant attendance with direct (one-on-one) patient contact. Ultrasound is a time-based service reported in 15-minute increments.

Ultrasound of area behind abdominal cavity (limited) [HCPCS 76775]

A real time retroperitoneal ultrasound is performed with image documentation. The patient is placed supine. Acoustic coupling gel is applied to the skin of the abdomen. The transducer is pressed firmly against the skin and swept back and forth over the abdomen and images obtained of the retroperitoneal area. The ultrasonic wave pulses directed at the retroperitoneum are imaged by recording the ultrasound echoes. Any abnormalities are evaluated to identify characteristics that might provide a definitive diagnosis. The physician reviews the ultrasound images of the retroperitoneum and provides a written interpretation.

Wrist x-ray (2 views) [HCPCS 73100]

A radiologic examination of the wrist is done. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. The radiographs may be taken to look for conditions such as fractures, dislocations, deformities, arthritis, foreign body, infection, or tumor. Wrist standard views include the front to back anteroposterior (AP) or back to front posteroanterior (PA) projection; the lateral view with the elbow flexed and the hand and wrist placed thumb up; and oblique views. Oblique views are obtained with the hand and wrist either supinated or pronated with the hand slightly flexed so the carpal target area lies flat, and then rotating the wrist 45 degrees externally or internally. A more specialized image may be obtained for assessing carpal tunnel. For the carpal tunnel view, the forearm is pronated with the palm down, and the wrist is hyperextended as far as possible by grasping the fingers with the opposite hand and gently hyperextending the joint until the metacarpals and fingers are in a near vertical position.

Wrist x-ray, complete study (minimum of 3 views) [HCPCS 73110]

X-ray of paranasal sinuses including side to side and back to front views (less than 3 views) [HCPCS 70210]

X-ray of sacrum and tailbone (minimum of 2 views) [HCPCS 72220]

A radiologic examination of the sacrum and coccyx is done with at least 2 views obtained. X-ray imaging uses indirect ionizing radiation to take pictures inside the body. X-rays work on non-uniform material, such as human tissue, because of the different density and composition of the object, which allows some of the x-rays to be absorbed and some to pass through and be captured behind the object on a detector. This produces a 2D image of the structures. Routine views include an anteroposterior (AP) or posteroanterior (PA) view of the sacrum, an AP or PA view of the coccyx, and lateral sacrum/coccyx views. For the sacral view, the patient's pelvis needs to be positioned correctly so the sacrum and sacroiliac joints are symmetrical. Because the coccyx has a forward curvature in relation to the sacrum, it is not automatically visualized when taking an AP view of the sacrum, and so another positioning is done for the coccyx. For lateral views, the patient stands sideways with feet shoulder width apart and arms crossed at the shoulders. Lateral imaging shows the entire 5th lumbar vertebra, the sacrum, and the coccyx. Good sacrum and coccyx imaging requires patient preparation with an empty bladder, clean colon, and removal of clothing in favor of wearing a gown. This is due to the difficulty these obstructions can cause in achieving a good radiographic image. Shielding is done for males, but is not possible for female patients.
