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.

Abdominal ultrasound of pregnant uterus after first trimester, greater than or equal to 14 weeks 0 days (single or first fetus) [HCPCS 76805]

A real time transabdominal obstetrical ultrasound is performed with image documentation to evaluate the fetus and the pregnant uterus and surrounding pelvic structures of the mother after the first trimester, which is defined as a gestation period equal to or greater than 14 weeks 0 days. Obstetric ultrasound is performed to establish viability of the fetus; to determine whether a multiple gestation exists; to determine fetal age using fetal measurements; to evaluate the position of the fetus and placenta; to survey fetal anatomy including intracranial, spinal, abdominal, and heart with four chamber evaluation; to identify umbilical cord insertion site; to evaluate amniotic fluid volume; and to evaluate the maternal uterus and adnexa if visible. The mother 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 pregnant uterus, surrounding pelvic structures, and fetus. The ultrasonic wave pulses directed at the fetus, pregnant uterus, and surrounding pelvic structures of the mother are imaged by recording the ultrasound echoes. Any abnormalities are evaluated. The physician reviews the ultrasound images of the fetus, pregnant uterus, and maternal pelvic structures, and provides a written interpretation.

Cataract removal involving removal of the front part of the capsule and the central part of the lens with lens prosthesis insertion [HCPCS 66984]

Colon (large bowel) examination and biopsy with endoscope [HCPCS 45380]

A flexible colonoscopy is performed with single or multiple biopsies. The colonoscope is inserted into the rectum and advanced through the colon to the cecum or a point within the terminal ileum, using air insufflation to separate the mucosal folds for better visualization. Mucosal surfaces of the colon are inspected and any abnormalities are noted. The endoscope is then withdrawn and mucosal surfaces are again inspected for ulcerations, varices, bleeding sites, lesions, strictures, or other abnormalities. Any suspect site(s) to be biopsied is identified and biopsy forceps are placed through the biopsy channel in the endoscope. The forceps are opened, the tissue is spiked, and the forceps are closed. The biopsied tissue is then removed through the endoscope. One or more tissue samples may be obtained and are sent for separately reportable laboratory analysis.

Colon (large bowel) examination and polyps or tumors removal by snare technique with endoscope [HCPCS 45385]

A flexible colonoscopy is performed with removal of tumors, polyps, or other lesions by hot biopsy forceps or snare technique. The colonoscope is inserted into the rectum and advanced through the colon to the cecum or a point within the terminal ileum, using air insufflation to separate the mucosal folds for better visualization. Mucosal surfaces of the colon are inspected and any abnormalities are noted. The tumor, polyp, or other lesion is identified. Hot biopsy method uses insulated monopolar forceps to remove and electrocoagulate (cauterize) tissue simultaneously. Hot biopsy forceps are used primarily for removal of small polyps and treatment of vascular ectasias. A wire snare loop is placed around the lesion. The loop is heated to shave off and cauterize the lesion. Lesions may be removed en bloc with one placement of the snare or in a piecemeal fashion which requires multiple applications of the snare. The endoscope is withdrawn and mucosal surfaces are again inspected for ulcerations, bleeding sites, lesions, strictures, or other abnormalities.

Colon (large bowel) examination with endoscope for diagnosis (high risk) [HCPCS 45378]

A flexible colonoscopy is performed with or without collection of specimens by brushing or washing. The colonoscope is inserted into the rectum and advanced through the colon to the cecum or a point within the terminal ileum, using air insufflation to separate the mucosal folds for better visualization. Mucosal surfaces of the colon are inspected and any abnormalities are noted. The endoscope is then withdrawn as mucosal surfaces are again inspected for ulcerations, varices, bleeding sites, lesions, strictures, or other abnormalities. Cytology (cell) samples may be obtained using a brush introduced through the endoscope. Alternatively, sterile water may be introduced to wash the mucosal lining and the fluid aspirated to obtain cell samples. Cytology samples are sent for separately reportable laboratory analysis.

Esophagus, stomach, and/or upper small bowel examination and biopsy with endoscope [HCPCS 43239]

An upper gastrointestinal (UGI) endoscopic examination, also referred to as an esophagogastroduodenoscopy (EGD), is performed on the esophagus, stomach, duodenum and/or jejunum with biopsy(s). The mouth and throat are numbed using an anesthetic spray. A hollow mouthpiece is placed in the mouth. The flexible fiberoptic endoscope is then inserted and advanced as it is swallowed by the patient. Once the endoscope has been advanced beyond the cricopharyngeal region, it is guided using direct visualization. The esophagus is inspected and any abnormalities are noted. The endoscope is then advanced beyond the gastroesophageal junction into the stomach and the stomach is insufflated with air. The cardia, fundus, greater and lesser curvature, and antrum are inspected and any abnormalities are noted. The tip of the endoscope is then advanced through the pylorus and into the duodenum and/or jejunum where mucosal surfaces are inspected for any abnormalities. Single or multiple samples of suspect tissue are taken through the scope. The endoscope is withdrawn and mucosal surfaces are again inspected for ulcerations, varices, bleeding sites, lesions, strictures, or other abnormalities.

Gallbladder removal with an endoscope [HCPCS 47562]

The gallbladder is removed by laparoscopic technique. A small portal incision is made at the navel and a trocar is inserted. The scope and video camera are then inserted at this site. The abdomen is inflated with carbon dioxide. Two to three additional abdominal portal incisions are made and trocars are inserted for placing surgical instruments. The gallbladder is identified. If the gallbladder is distended, a needle may be used to drain bile from the gallbladder. Grasper clamps are applied. The Hartmann's pouch is identified and retracted, exposing the triangle of Calot. The cystic artery and cystic duct are identified. The cystic duct is dissected free and transected. The cystic artery is dissected free, ligated, and doubly divided. Electrocautery is used to dissect the gallbladder off the liver bed. The gallbladder is placed in an extraction sac and removed from the abdomen through one of the small incisions.

Groin hernia repair for patient 5 years of age or older (herniated tissue that is not trapped) [HCPCS 49505]

An initial inguinal hernia repair is performed on a patient who is five years or older. An inguinal hernia is a condition where structures protrude through a weakness in the abdominal wall in the groin area. Incarcerated hernia tissue cannot be pushed back into its normal position. Strangulated hernias are those in which circulation is compromised. An incision is made over the internal ring. The skin, fat, and subcutaneous fascia are incised down to the aponeurosis of the external oblique muscle. The external ring is identified and the external oblique aponeurosis is slit. The internal ring is opened and the inguinal canal is exposed. In males, the spermatic cord and its covering are mobilized and the covering is removed. The hernia sac is dissected free into the retroperitoneum, opened, and inspected for the presence of bowel or bladder wall. Any bowel or bladder content is reduced (pushed back into the abdominal cavity) and the hernia sac is transected and inverted into the abdominal cavity. A mesh plug may be placed to reinforce the repair. In women, the sac is inspected for the ovary. If the ovary is present, it is returned to the abdomen. The sac is then resected together with the round ligament. The internal ring is closed and the posterior wall of the inguinal canal is repaired.

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 brain by MRI without contrast, followed by contrast [HCPCS 70553]

Magnetic resonance imaging is done on the brain. MRI is a noninvasive, non-radiating imaging technique that uses the magnetic properties of hydrogen atoms in the body. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. The powerful magnetic field forces the hydrogen atoms to line up. Radiowaves are then transmitted within the strong magnetic field. Protons in the nuclei of different types of tissues emit a specific radiofrequency signal that bounces back to the computer, which processes the signals and converts the data into tomographic, 3D images with very high resolution. MRI of the brain provides reliable information for diagnosing the presence, location, and extent of tumors, cysts, or other masses; swelling and infection; vascular disorders or malformations, such as aneurysms and intracranial hemorrhage; disease of the pituitary gland; stroke; developmental and structural anomalies of the brain; hydrocephalus; and chronic conditions and diseases affecting the central nervous system such as headaches and multiple sclerosis.

Imaging of leg joint by MRI without contrast [HCPCS 73721]

Magnetic resonance imaging is done on a joint of the upper or lower leg. Magnetic resonance is a noninvasive, non-radiating imaging technique that uses the magnetic properties of hydrogen atoms in the body. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. The powerful magnetic field forces the hydrogen atoms to line up. Radiowaves are then transmitted within the strong magnetic field. Protons in the nuclei of different types of tissues emit a specific radiofrequency signal that bounces back to the computer, which processes the signals and converts the data into tomographic, 3D images with very high resolution. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. Small coils that help transmit and receive the radiowaves may be placed around the joint. MRI scans on joints of the lower extremity are often done for injury, trauma, unexplained pain, redness, or swelling, and freezing of a joint with loss of motion. MRI scans provide clear images of areas that may be difficult to see on CT. The physician reviews the images to look for information that may correlate to the patient's signs or symptoms. MRI provides reliable information on the presence and extent of tumors, masses, or lesions within the joint; infection, inflammation, and swelling of soft tissue; muscle atrophy and other anomalous muscular development; and joint effusion and vascular necrosis.

Imaging of lower spinal canal by MRI without contrast [HCPCS 72148]

Magnetic resonance imaging (MRI) is done on the lumbar spinal canal and contents. MRI is a noninvasive, non-radiating imaging technique that uses the magnetic properties of nuclei within hydrogen atoms of the body. The powerful magnetic field forces the hydrogen atoms to line up. Radiowaves are then transmitted within the strong magnetic field. Protons in the nuclei of different types of tissues emit a specific radiofrequency signal that bounces back to the computer, which records the images. The computer processes the signals and coverts the data into tomographic, 3D, sectional images in slices with very high resolution. The patient is placed on a motorized table within a large MRI tunnel scanner that contains the magnet. MRI scans of the spine are often done when conservative treatment of back pain is unsuccessful and more aggressive treatments are considered or following surgery. The physician reviews the images to look for specific information that may correlate to the patient's symptoms, such as abnormal spinal alignment; disease or injury of vertebral bodies; intervertebral disc herniation, degeneration, or dehydration; the size of the spinal canal to accommodate the cord and nerve roots; pinched or inflamed nerves; or any changes since surgery.

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 complete blood cell count (red cells, white blood cell, and platelets), automated test [HCPCS 85027]

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

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.

Pelvis CT scan with contrast to examine injury, foreign bodies, or tumors [HCPCS 72193]

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.

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.

Psychotherapy treatment by physician face-to-face with patient (30 minutes) [HCPCS 90832]

Spinal fusion other than the neck without major complications

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.

Critical care delivery to critically ill or injured patient (each additional 30 minutes) [HCPCS 99292]

Emergency department visit for problem with significant threat to life [HCPCS 99285]

Emergency department visit for the evaluation and management of a patient, which requires these 3 key components within the constraints imposed by the urgency of the patient's clinical condition and/or mental status: A comprehensive history; A comprehensive examination; and Medical decision making of high complexity. Counseling and/or coordination of care with other physicians, other qualified health care professionals, or agencies are provided consistent with the nature of the problem(s) and the patient's and/or family's needs. Usually, the presenting problem(s) are of high severity and pose an immediate significant threat to life or physiologic function.

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.

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 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, 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 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.

Heart and blood vessel stress test with EKG tracing and monitoring (exercise or drug-induced) [HCPCS 93017]

An ECG is used to evaluate the electrical activity of the heart using treadmill, bicycle exercise, and/or pharmacologically induced stress. Small plastic patches are attached at specific locations on the chest, abdomen, arms, and/or legs. Leads (wires) from the stress ECG device are then attached to the patches. A baseline ECG is obtained. The exercise portion of the study is then initiated. Heart rate and blood pressure are monitored. Staged stress protocol is used and the patient's response to stress is monitored as the stress ECG is recorded. Unless contraindicated, exercise or pharmacological stress continues until the patient is unable to continue or until the target heart rate is achieved. Upon completion of the study, the stress ECG is reviewed and a written interpretation of findings is provided.

Routine EKG (electrocardiogram) tracing using at least 12 wires [HCPCS 93005]

An ECG is used to evaluate the electrical activity of the heart. The test is performed with the patient lying prone on the exam table. Small plastic patches are attached at specific locations on the chest, abdomen, arms, and/or legs. Leads (wires) from the ECG tracing device are then attached to the patches. A tracing is obtained of the electrical signals from the heart. Electrical activity begins in the sinoatrial node which generates an electrical stimulus at regular intervals, usually 60 to 100 times per minute. This stimulus travels through the conduction pathways to the sinoatrial node causing the atria to contract. The stimulus then travels along the bundle of His which divides into right and left pathways providing electrical stimulation of the ventricles causing them to contract. Each contraction of the ventricles represents one heart beat. The ECG tracing includes the following elements: P wave, QRS complex, ST segment, and T wave. The P wave, a small upward notch in the tracing, indicates electrical stimulation of the atria. This is followed by the QRS complex which indicates the ventricles are electrically stimulated to contract. The short flat ST segment follows and indicates the time between the end of the ventricular contraction and the T wave. The T wave represents the recovery period of the ventricles. The physician reviews, interprets, and provides a written report of the ECG recording taking care to note any abnormalities.

Oxygen saturation measurement in blood by ear or finger device (single determination) [HCPCS 94760]

Ear or pulse oximetry measures the percentage of hemoglobin (Hb) that is saturated with oxygen and is used to monitor oxygen saturation of blood and detect lower than normal levels of oxygen in the blood. Oximeters also record pulse rate and provide a graphical display of blood flow past the probe. A probe is attached to the patient's ear lobe or finger. The probe is connected to a computerized unit. A light source from the probe is emitted at two wavelengths. The light is partially absorbed by Hb in amounts that differ based on whether the Hb is saturated or desaturated with oxygen. The absorption of the two wavelengths is then computed by the oximeter processer and the percentage of oxygenated Hb is displayed. The oximeter can be programmed to sound an audible alarm when the oxygen saturation of blood falls below a certain level.

Knee joint repair at lower or upper part of joint (inside and outside compartments [HCPCS 27447]

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 aorta ultrasound for screening of abdominal aortic aneurysm [HCPCS 76706]

Abdominal CT scan with contrast for injury, foreign bodies, or tumors [HCPCS 74160]

Diagnostic computed tomography (CT) is done on the abdomen to provide detailed visualization of the tissues and organs within the abdominal area. 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 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 abdomen. The physician reviews the images for the cause of abdominal pain, swelling, and fever; for other suspected problems such as appendicitis and kidney stones; for locating tumors, abscesses, or masses; or for evaluating the abdominal area for hernias, infections, or internal injury. The physician reviews the CT scan, notes any abnormalities, and provides a written interpretation of the findings.

The physician reviews the CT scan, notes any abnormalities, and provides a written interpretation of the findings.

Abdominal x-ray, complete study including 2 or more views of abdomen and single view of chest [HCPCS 74022]

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.

Arm CT scan without contrast for injury, foreign bodies, or tumors [HCPCS 73200]

Diagnostic computed tomography (CT) is done on the upper extremity to provide detailed visualization of the tissues and bone structure of the arm. 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 arm 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 upper extremity. The physician reviews the CT scan, notes any abnormalities, and provides a written interpretation of the findings. The physician reviews the images to look for suspected problems with the arm such as locating tumors, abscesses, or masses; evaluating the bones for degenerative conditions, fractures, or other injury following trauma; and finding the cause of pain or swelling.

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.

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.

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.

CTA scan of chest blood vessels with contrast to examine injury, foreign bodies, or tumors [HCPCS 71275]

A computed tomographic angiography (CTA) of the noncoronary vessels of the chest 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 noncoronary vessels of the chest.

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.

Digital tomography of both breasts (screening exam) [HCPCS 77063]

Digital screening mammogram

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.

Esophagus x-ray with barium swallow (single contrast material swallowed) [HCPCS 74220]

Oral contrast material is swallowed and the passage of the contrast is observed fluoroscopically as it passes through the pharynx and/or esophagus. Once the lumen of the pharynx and/or esophagus is completely coated with contrast material, still radiographic images are obtained. The physician reviews the images, notes any abnormalities, and provides a written interpretation of the findings.

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.

Fluoroscopic guidance for needle placement [HCPCS 77002]

Fluoroscopy imaging guidance for procedure (up to 1 hour) [HCPCS 76000]

Foot x-ray, complete study (minimum of 3 views) [HCPCS 73630]

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.

Hand x-ray (minimum of 2 views) [HCPCS 73130]

A radiologic examination of the hand 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, 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.

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 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. 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.

Hip x-ray of hip with pelvis (single view) [HCPCS 73501]

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. 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.

Imaging of heart vessels with SPECT tomography and drugs or exercise (multiple studies) [HCPCS 78452]

Myocardial perfusion imaging is a nuclear medicine procedure used to evaluate the heart muscle and blood flow to the heart. An intravenous line is inserted into a vein in the hand or arm. ECG leads are placed and a blood pressure cuff is placed on the arm. The patient lies flat on a table in the procedure room for myocardial perfusion imaging performed at rest. For a stress study, the patient is either on a treadmill or bike or an injection of a pharmacologic agent is administered to stress the heart. A radionuclide, also called a tracer, is injected into the intravenous line and allowed to circulate. The radionuclide localizes in healthy heart tissue. Ischemic heart tissue does not absorb the radionuclide. Images of the heart and great vessels are obtained using single photon emission computed tomography (SPECT). When SPECT images are obtained, the scanner rotates around the body to obtain images in multiple planes. The physician evaluates heart wall motion to determine how effective the heart muscle is in pumping blood through the heart and to the peripheral vascular system. Ejection fraction, which is the percentage of blood pumped out of the heart to the peripheral vascular system, is measured using either a first pass or gated technique. In a first pass technique, images are obtained as the blood circulates through the heart during the first pass of the radionuclide. In a gated technique, a series of images are obtained between heart beats. Using electrical signals from the heart, the camera captures a series of images as the heart rests, creating very sharp, high resolution images. Additional images are obtained as needed. The physician reviews the images, calculates the ejection fraction and quantifies other parameters of heart function based on the distribution of the radionuclide. The physician then provides a written report of findings.

Imaging of scrotum by ultrasound [HCPCS 76870]

An ultrasound examination of the scrotum and its contents is a non-invasive procedure that uses a transducer probe placed firmly against the skin to deliver high frequency sound waves and create a gray scale and/or color (Doppler) image of the internal anatomy. Ultrasound may be used to detect scrotal masses/tumors and undescended testicle(s), as well as to evaluate testicular torsion, scrotal injury or trauma, hydrocele(s), varicocele(s), and male infertility. Ultrasonic conduction gel is applied to the scrotum and the transducer probe is held against the skin and swept over the area. The images produced are captured on a screen and viewed in real-time and/or saved for later analysis.

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.

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.

Spinal CT scan of lower spine without contrast to examine injury, foreign bodies, or tumors [HCPCS 72131]

Diagnostic computed tomography (CT) is done on the lumbar spine. 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 spine 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 lumbar spine. The physician reviews the images to look for suspected problems with the spine such as bone disease, and evaluate for fractures or other injuries as well as birth defects of the spine in children.

Spinal CT scan of upper spine without contrast to examine injury, foreign bodies, or tumors [HCPCS 72125]

Diagnostic computed tomography (CT) is done on the cervical spine. 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 spine 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 cervical spine.

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.

Transthoracic echocardiography with contrast, or without contrast followed by with contrast, real-time with image documentation (2d), includes m-mode recording, when performed, complete, with spectral doppler echocardiography

Ultrasound guidance for needle placement including imaging supervision of procedure and interpretation of results [HCPCS 76942]

Ultrasound guidance including imaging supervision and interpretation is performed for needle placement during a separately reportable biopsy, aspiration, injection, or placement of a localization device. A local anesthetic is injected at the site of the planned needle or localization device placement. A transducer is then used to locate the lesion, site of the planned injection, or site of the planned placement of the localization device. The radiologist constantly monitors needle placement with the ultrasound probe to ensure the needle is properly placed. The radiologist also uses ultrasound imaging to monitor separately reportable biopsy, aspiration, injection, or device localization procedures. Upon completion of the procedure, the needle is withdrawn and pressure applied to control bleeding. A dressing is applied as needed. The radiologist then provides a written report of the ultrasound imaging component of the procedure.
