Immunization administration of vaccine into, between, or beneath the skin or into muscle (single vaccine) [HCPCS 90471]

A single vaccine or a combination vaccine/toxoid is administered by injection to a patient over age 18 with or without a face-to-face encounter with the physician or other health care professional. These codes are also used when a vaccine/toxoid is given to a patient age 18 or younger without any face-to-face counseling by the physician or other health care professional. Routes of administration include percutaneous, intradermal, subcutaneous, or intramuscular.

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.

Application of medication using electrical current, each 15 minutes

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.

Tetanus, diphtheria toxoids and acellular pertussis (whooping cough) vaccine for injection into muscle (7 years of age or older) [HCPCS 90715]

Toxoids provide long lasting immunity by stimulating the body's own defense system to make antibodies that destroy specific toxins produced by bacteria. Vaccines also provide active, long-term immunity by exposing the recipient's immune system to altered versions of specific viruses or bacteria that induce the immune system to produce its own antibodies against the invading micro-organism. The body then remembers how to make antibodies when exposed to these same agents again. The toxoid vaccine is an inactivated poison, called a toxin, produced by culturing the bacteria in a liquid medium, then purifying and inactivating the poison produced by the bacteria. Since toxoids are not a live vaccine, booster doses are recommended because immunity will decline over time. These tetanus toxoid combinations are formulations for adults and those over 7 years of age, given by intramuscular injection.

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.

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.

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.

Drug administration into vein by infusion for therapy, prevention, or diagnosis (concurrent with another infusion) [HCPCS 96368]

An intravenous infusion of a specified substance or drug is administered for therapy, prophylaxis, or diagnosis. An intravenous line is placed into a vein, usually in the arm, and the specified substance or drug is administered. The physician provides direct supervision of the administration and is immediately available to intervene should complications arise. The physician provides periodic assessments of the patient and documentation of the patient's response to treatment.

Drug administration into vein by infusion for therapy, prevention, or diagnosis (up to 1 hour) [HCPCS 96365]

An intravenous infusion of a specified substance or drug is administered for therapy, prophylaxis, or diagnosis. An intravenous line is placed into a vein, usually in the arm, and the specified substance or drug is administered. The physician provides direct supervision of the administration and is immediately available to intervene should complications arise. The physician provides periodic assessments of the patient and documentation of the patient's response to treatment.

Airway inhalation treatment to relieve airway obstruction or for sputum collection (inhaled pressure or nonpressure treatment) [HCPCS 94640]

The patient is placed on intermittent inhalation treatment for acute airway obstruction or to induce sputum production for therapeutic and/or diagnostic purposes. To treat acute airway obstruction, pressurized or nonpressurized bronchodilator medication is delivered for short intervals several times a day using an inhaler, nebulizer, aerosol generator, or an intermittent positive pressure breathing (IPPB) device. Bronchodilator medication is suspended as fine particles within a gaseous propellant and taken into the lungs as a fine spray. The medication acts to relax the smooth muscle of the bronchioles and lung tissue, which has constricted in conditions such as an asthma attack or hypersensitivity reaction, severely restricting air flow. The patient uses the prescribed pressurized or nonpressurized inhalation device as directed by the physician typically for 10-15 minutes several times during the day. To induce sputum production for diagnostic purposes, an isotonic or hypertonic solution is delivered using a nebulizer or other device. These solutions induct secretion of sputum in the lower airways. The patient must cough to expectorate the secretions which are collected in a sterile container and sent to the laboratory for separately reportable analysis.

Drug administration into vein by push technique for therapy, diagnosis, or prevention (each additional push of new drug) [HCPCS 96375]

A therapeutic, prophylactic, or diagnostic injection is administered by intravenous push (IVP) technique. The specified substance or drug is injected using a syringe directly into an injection site of an existing intravenous line or intermittent infusion set (saline lock). The injection is given over a short period of time, usually less than 15 minutes.

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.

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.

Amount and speed of breathed air measurement and graphic recording before and after medication administration [HCPCS 94060]

Spirometry with bronchodilation responsiveness is a pulmonary function test that is used to help diagnose the cause of shortness of breath and to monitor existing pulmonary disease, such as chronic bronchitis, emphysema, pulmonary fibrosis, chronic obstructive pulmonary disease (COPD), and asthma. The test is first performed without administration of a bronchodilator. A spirometry device consisting of a mouthpiece and tubing connected to a machine that records and displays results is used to perform the test. The patient inhales deeply and then exhales through the mouthpiece. Inhalation and exhalation measurements are first taken with the patient breathing normally. The patient is then instructed to perform rapid, forceful inhalation and exhalation. The spirometer records the volume of air inhaled, exhaled, and the length of time each breath takes. A bronchodilator medication is administered and the test is repeated. The test results are displayed on a graph that the physician reviews and interprets in a written report.

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.

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 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 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.

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.

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.

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.

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.

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.

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 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 of blood culture to identify bacteria [HCPCS 87040]

A blood sample is drawn and placed in a medium conducive to the growth of bacteria. Any bacteria present in the blood sample will then reveal themselves.

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 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 urine culture to identify bacteria [HCPCS 87088]

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.

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

A blood sample is taken to measure creatinine levels. Creatinine is a waste product produced by the muscles in the breakdown of creatine, which is a compound used by the muscles to create energy for contraction. The waste product, creatinine, is excreted by the kidneys and blood levels provide a good measurement of renal function. Creatinine may be checked to screen for or monitor treatment of renal disease. Creatinine levels may also be monitored in patients with acute or chronic illnesses that may impair renal function and in patients on medications that affect renal function. Creatinine is measured using spectrophotometry.

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 gases with oxygen saturation [HCPCS 82805]

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 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 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 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.

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 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 blood analysis to identify antigens on red blood cell surface and determine the patient's Rh (D) type (Rh positive or Rh negative) [HCPCS 86901]

A blood specimen is tested to determine blood type (ABO) or Rh(D). In Rh(D), blood is tested for Rh factor, which is an antigen on red blood cells. Blood is Rh+ if the antigen is present or Rh- if the antigen is absent. Blood is tested by mixing the blood sample with antibodies against Rh factor and then checking for agglutination. If agglutination occurs, the blood is Rh+. If the blood does not agglutinate, it is Rh-.

Lab blood analysis to confirm blood unit compatibility by immediate spin technique [HCPCS 86920]

A laboratory test is performed to determine the donor-recipient compatibility of a unit of blood. Compatibility testing may also be referred to as cross matching (CM). Immediate spin technique (ISCM) mixes recipient plasma or serum with donor red cells, centrifuges them immediately, and observes any hemolysis and/or agglutination. ISCM will not detect all ABO incompatibilities; however, a negative result indicates the blood of the donor and recipient are compatible and the unit may be transfused.

Lab analysis to measure the carcinoembryonic antigen (cea) protein level [HCPCS 82378]

A laboratory test is obtained to measure carcinoembryonic antigen (CEA) levels in blood and body fluids. CEA is a protein normally present at high levels during fetal development but is low or absent after birth. Elevated levels of CEA may occur with colorectal, breast, lung, pancreatic, prostate, ovarian, and medullary thyroid cancers. CEA testing can help determine tumor size, stage, and metastasis. A baseline level is usually obtained following a cancer diagnosis. Serial testing is done to monitor treatment and response to therapy. Elevated levels of CEA have also been noted in smokers and in patients diagnosed with inflammatory disorders, cirrhosis, peptic ulcer, ulcerative colitis, rectal polyps, emphysema, and benign breast disease. CEA testing should not be used for screening in the general population. A blood sample is obtained by separately reportable venipuncture. Cerebral spinal fluid (CSF) is obtained by separately reportable lumbar puncture. Pleural and peritoneal fluids are obtained by needle aspiration. Serum/plasma and body fluids are tested using quantitative 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 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 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 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 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 to test for kidney function or muscle injury (other than blood specimen) [HCPCS 82570]

A sample other than blood is taken to measure creatinine levels. Creatinine is a waste product produced by the muscles in the breakdown of creatine, which is a compound used by the muscles to create energy for contraction. The waste product, creatinine, is excreted by the kidneys and blood levels provide a good measurement of renal function. Creatinine may be checked to screen for or monitor treatment of renal disease. Creatinine levels may also be monitored in patients with acute or chronic illnesses that may impair renal function and in patients on medications that affect renal function. Creatinine clearance, also known as urea or urea nitrogen clearance tests both blood and urine samples for a calculation of creatinine content adjusted for urine volume and physical size as a general indicator of glomerular filtration function.

Lab analysis to measure the cyanocobalamin (vitamin b-12) level [HCPCS 82607]

Cyanocobalamin is a vitamer of the B-12 vitamin family and plays an important role in metabolism, red blood cell production and nervous system function. Blood levels of cyanocobalamin are measured. 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 by immunoassay (ELISA) to identify infectious organism antigen (multiple-step method, each organism) [HCPCS 87449]

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 to evaluate an antimicrobial drug (antibiotic, antifungal, antiviral) by disk method (per plate) [HCPCS 87184]

Lab analysis to measure the ferritin (blood protein) level [HCPCS 82728]

A blood test is performed to measure ferritin levels. Ferritin is an intracellular protein that stores iron and releases it into circulation in a controlled manner to protect the body against iron overload and iron deficiency. Ferritin levels may be obtained to evaluate for elevated levels caused by excess storage diseases such as hemochromatosis and following multiple transfusions. Levels may also be obtained to evaluate for decreased levels due to iron deficiency. A blood sample is obtained by separately reportable venipuncture. Serum is tested using quantitative chemiluminescent immunoassay.

Lab analysis to measure the folic acid level in serum specimen [HCPCS 82746]

A blood test is performed to measure folic acid (folate) levels in serum or red blood cells (RBC). Folic acid (folate) may also be referred to as Vitamin B9 and is essential for the growth, division and repair of cells, especially fetal growth during pregnancy and in early infancy. It is also necessary for the production of healthy red blood cells and to prevent anemia at all ages. The test may be used to diagnose anemia or certain neuropathies and to monitor the effectiveness of treatment for these conditions. A blood sample is obtained by separately reportable venipuncture.

Lab analysis to measure the hemoglobin A1C level in blood specimen [HCPCS 83036]

A blood test is performed to measure glycosylated hemoglobin (HbA1C) levels. Plasma glucose binds to hemoglobin and the HbA1C test measures the average plasma glucose concentration over the life of red blood cells (approximately 90-120 days). HbA1C levels may be used as a diagnostic reference for patients with suspected diabetes mellitus (DM) and to monitor blood glucose control in patients with known DM. HbA1C levels should be monitored at least every 6 months in patients with DM and more frequently when the level is >7.0%. A blood sample is obtained by separately reportable venipuncture. Whole blood is tested using quantitative high performance liquid chromatography/boronate affinity.

Lab analysis to measure the iron binding capacity [HCPCS 83550]

A blood test is performed to measure the iron binding capacity of transferrin. Transferrin, a protein found in circulating blood is responsible for carrying iron molecules. This test measures the ability of transferrin to carry iron. A blood sample is obtained by separately reportable venipuncture. Serum or plasma is tested using quantitative spectrophotometry/calculation.

Lab analysis to measure the iron level [HCPCS 83540]

A blood, urine or liver test is performed to measure iron levels. Iron (Fe) is an essential element that circulates in the blood attached to the protein transferrin. Iron is necessary component of hemoglobin, found in red blood cells (RBCs) and myoglobin found in muscle cells. Low iron levels may cause a decrease in red blood cells and iron deficiency anemia. High iron levels may be caused by excessive intake of iron supplements or a hereditary genetic condition such as hemochromatosis from a mutation of the RGMc gene or HAMP gene. A blood sample is obtained by separately reportable venipuncture. Serum or plasma is tested using quantitative spectrophotometry. A random voided or 24 hour urine specimen is obtained and tested using quantitative inductively coupled plasma/emission spectrometry. Patient should wait 2-4 days after receiving iodine or gadolinium contrast media to collect a urine specimen. A liver sample is obtained by a separately reportable procedure. Liver tissue is tested using quantitative inductively coupled plasma-mass spectrometry.

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 measure the lactic acid level in blood, plasma, or cerbrospinal fluid specimen [HCPCS 83605]

A blood or body fluid test is performed to measure lactate (lactic acid) levels. Lactic acid is produced primarily by muscle tissue and red blood cells in the body. Elevated levels may be caused by strenuous exercise, heart failure, severe infection (sepsis), shock states (cardiogenic, hypovolemic) and liver disease. A blood sample is obtained by separately reportable venipuncture. Cerebral spinal fluid (CSF) is obtained by lumbar puncture (spinal tap). Other body fluids may also be collected and tested. Plasma, CSF, and other body fluids are tested using enzymatic methodology.

Lab analysis to measure the lipase (fat enzyme) level [HCPCS 83690]

A test is performed on blood and body fluids to measure lipase levels. Lipase is an enzyme released by the pancreas into the small intestine and is essential for the digestion of dietary fats. Elevated levels may result from small bowel obstruction, celiac disease, cholecystitis, duodenal ulcer, severe gastroenteritis, macrolipasemia, pancreatitis, and pancreatic tumors. The test may be ordered when there is a family history of lipoprotein lipase deficiency. A blood sample is obtained by separately reportable venipuncture. Other body fluids collected by other methods. Blood and other body fluids are tested using quantitative enzymatic methodology.

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 magnesium level in body fluids and cells [HCPCS 83735]

A blood, urine, or fecal test is performed to measure magnesium levels. Magnesium is an essential dietary mineral responsible for enzyme function, energy production, and contraction and relaxation of muscle fibers. Decreased levels may result from severe burns, metabolic disorders, certain medications, and low blood calcium levels. A blood sample is obtained by separately reportable venipuncture. Red blood cells (RBCs) are tested using quantitative inductively coupled plasma-mass spectrometry. Serum/plasma is tested using quantitative spectrophotometry. A 24-hour voided urine specimen is tested using quantitative spectrophotometry. A random or 24-hour fecal sample is tested using quantitative spectrophotometry.

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 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 immune system protein (complement) antigens (each component) [HCPCS 86160]

A blood test is performed to measure complement antigen levels. Complement factors help to clear immune complexes from the blood. Proteins are activated in response to the immune complex and generate peptides that bind the complexes and complement receptors. The cell membrane breaks apart and an attack complex is formed. A blood sample is obtained by separately reportable venipuncture. Complements are tested in serum or plasma samples, using specified methods, particularly quantitative radial immunodiffusion. Report for each complement component tested: 2-9 (2 being the most common inherited complement deficiency), 3A (the most abundant of all complement components), 4A, and 1Q; complement factor B and Bb; and C1-esterase inhibitor.

Lab analysis to measure the natriuretic peptide (heart and blood vessel protein) level in plasma specimen [HCPCS 83880]

The level of the natriuretic peptide in the blood is measured to evaluate heart failure and to differentiate symptoms that might be indicative of heart failure from other disorders that cause similar symptoms. A separately reportable venipuncture is performed and whole blood or plasma collected using EDTA as an anticoagulant. An automated immunoassay is performed using murine monoclonal and polyclonal antibodies against natriuretic peptide. The antibodies are labeled with a fluorescent dye and immobilized on the solid phase. The specimen is placed in the sample chamber and the analysis is run. The physician reviews the results and uses them to make diagnosis and treatment decisions.

Lab analysis to measure the level of blood proteins (nephelometry) using light [HCPCS 83883]

Lab analysis to measure the parathormone (parathyroid hormone) level [HCPCS 83970]

A blood or tissue test is performed to measure parathormone (parathyroid hormone, parathyrin) levels. Parathyroid hormone (PTH) is produced by chief cells in the parathyroid gland. The hormone helps to regulate blood calcium levels, absorption/excretion of phosphate by the kidneys and in Vitamin D synthesis in the body. Elevated levels (hyperparathyroidism) may be caused by parathyroid gland tumors or chronic renal failure. Decreased levels (hypoparathyroidism) may result from inadvertent removal (during thyroid gland surgery), autoimmune disorders or genetic inborn errors of metabolism. A blood sample is obtained by separately reportable venipuncture. Parathyroid gland tissue is obtained by separately reportable fine needle aspirate. Serum/plasma or tissue sample are tested using quantitative electrochemiluminescent immunoassay. Plasma is tested for parathyroid hormone, CAP (Cyclase Activating Parathyroid Hormone) using immunoradiometric assay.

Lab analysis to measure the phosphate level [HCPCS 84100]

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 amount of protein in serum specimen [HCPCS 84165]

A blood test is performed to measure protein levels in serum. This test is often performed in conjunction with total protein to detect pathophysiologic states such as inflammation, gammopathies, and dysproteinemias. 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 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 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 to measure red blood count (automated test) [HCPCS 85045]

An automated reticulocyte count is performed. Reticulocytes are new red blood cells (RBCs) that circulate in the peripheral blood for 1-2 days before losing sufficient RNA to become mature RBCs. A reticulocyte count may be performed when a blood test shows decreased RBCs and/or decreased hemoglobin or hematocrit measurements. The test can help determine if the bone marrow is responding to the body's need for RBCs. Indications for monitoring reticulocytes include vitamin B12 or folate deficiency, kidney disease, chemotherapy, bone marrow transplant, and treatment with erythropoietin or darbepoetin. A blood sample is obtained. A reticulocyte count is performed with an automated blood cell counting instrument. Automated reticulocyte count performed alone is reported. When automated reticulocyte count is performed with direct measurement of one or more cellular parameters, such as reticulocyte hemoglobin content (CHr), immature reticulocyte fraction (IRF), mean reticulocyte volume (MRV), or RNA content is reported. CHr measures the amount of hemoglobin in reticulocytes, which is an indicator of iron utilization for RBC production, and is used to diagnosis iron deficiency. IRF is used to determine whether reticulocytes are being released prematurely and to quantify the proportion of immature reticulocytes. Premature release occurs during periods of high demand for RBCs in chronic kidney disease, following chemotherapy or bone marrow transplant, or in patients with AIDs or malignant disease, as well as other conditions. IRF is calculated as a ratio of immature reticulocytes to the total number of reticulocytes (both immature and mature). MRV looks at the total volume of reticulocytes compared to total red blood cells and is used to evaluate iron utilization. RNA content is evaluated to determine the maturity of circulating reticulocytes.

Lab analysis to screen for pathogenic organisms [HCPCS 87081]

This test is performed when a specific pathogen is suspected. A blood sample is taken and placed in a medium conducive to the growth of the suspected pathogen. Any colonies that grow in the medium are then examined.

Lab blood analysis to screen for antibodies to red blood cell antigens (each serum technique) [HCPCS 86850]

A blood sample is tested for antibodies directed against red blood cell (RBC) antigens other than A and B antigens. This test may also be referred to as an indirect antiglobulin test (IAT). This test is performed as part of a blood typing and screening test when it is anticipated that a blood transfusion might be required. If an antibody is detected, then separately reportable antibody identification is performed to identify the specific antibodies present. The test may be performed using IAT methodology or another serum technique such as solid phase. If multiple serum techniques are used, each reported separately.

Lab analysis to measure the amount of blood in stool specimen by peroxidase activity [HCPCS 82272]

A fecal (stool) sample is obtained for colorectal neoplasm screening and tested for the presence of occult (hidden) blood by peroxidase activity. This test is also referred to as a fecal occult blood test (FOBT). Occult blood in a stool specimen is present in amounts too small to see with the naked eye, but becomes visible when chemical tests are performed. Guaiac is one type of chemical (reagent) test that can be performed to identify the presence of blood in the stool. If the test is performed in an office or hospital, the physician may obtain the sample during a rectal exam. If the test is performed at home, the patient is provided with a stool collection kit consisting of three cards or a single triple card. The patient obtains three consecutive stool specimens per the kit instructions. The stool specimens are then returned to the physician office or mailed to a laboratory. All three specimens are then tested using a chemical reagent for the presence of occult blood. A few drops of the chemical reagent are applied to each stool specimen. If blood is present, a color change will be detected on the card.

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 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.

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 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 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 of urine specimen by dipstick without microscope (non-automated) [HCPCS 81002]

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 of urine specimen by dipstick to detect the hormone found in women in early pregnancy [HCPCS 81025]

Pregnancy tests detect the presence of human chorionic gonadotropin (hCG) in the urine. HCG is produced by the placenta and can be detected in urine shortly after the embryo attaches to the uterine lining. The test may be performed by collecting a urine specimen and dipping a stick treated to detect the presence of hCG in the urine. The presence of hCG is indicated by a color change in the treated section of the dipstick indicating a positive pregnancy test. If no color change occurs, the test is negative.

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.

Mammography of one breast for diagnosis [HCPCS 77065]

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. 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.

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.

Imaging for swallowing function evaluation with contrast [HCPCS 74230]

A radiologic study with cineradiography/videoradiography may be performed to assess swallowing function in patients with dysphagia. A swallowing function study (modified barium swallow, MBS) may be indicated for patients with a history of stroke or other central nervous system (CNS) disorders, surgery or radiation to the head/neck, neuromuscular or rheumatologic disease, generalized debilitation and  head/neck/throat injury including peripheral nerve injury. The patient is seated upright or semi-reclining with the fluoroscopy machine focused on the head and neck. Food and liquids of various texture and quantity are mixed or soaked in contrast medium (barium) and administered to the patient. A fluoroscopic recording is made of the food or fluid in the oral cavity, larynx, pharynx, and upper esophagus to document mastication and tongue mobility, elevation and retraction of the velum, tongue base retraction and movement of the hyoid bone and larynx, closure of the larynx, contraction of the pharynx, and the duration and extent of pharyngoesophageal segment opening. Observation and recording is made of any penetration or aspiration of food and fluid into the upper airways. The measurement of muscle sensation and strength may be inferred or calculated directly from the information obtained during the study.

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

Breast ultrasound (one breast, limited) [HCPCS 76642]

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.

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.

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.

Joint or other non-blood vessel structure of arm or leg ultrasound (partial) [HCPCS 76882]

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.

Chest CT scan without contrast to screen for lung cancer (low dose) [HCPCS 71271]

Imaging of abdomen by MRI without contrast, followed by contrast [HCPCS 74183]

Magnetic resonance imaging is done on the abdomen. 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 abdomen. MRI is often done for trauma and suspected internal injury, and unexplained abdominal pain, swelling, and fever. 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, such as the location of tumors, abscesses, or masses; the presence of kidney stones, hernias, appendicitis or other infections, and internal injury.

Imaging of head blood vessels by MRA without contrast [HCPCS 70544]

Magnetic resonance angiography (MRA) is performed on the head without contrast materials, with contrast materials, and without contrast materials followed by contrast materials. MRA is a noninvasive radiology procedure used to evaluate arterial and venous vessels for conditions such as atherosclerotic stenosis, arterial dissection, acute thrombosis, aneurysms or pseudo-aneurysms, vascular loops, vascular malformations/tumors, or arterial causes of pulsatile tinnitus. MRA may be performed following vascular surgery on the intracranial vessels to assess vascular status. MRA uses a magnetic field and pulses of radiowave energy to provide images of the blood vessels. Multiple images, 1-2 mm in thickness, are obtained and then processed using an array algorithm to produce maximum intensity projections (MIPs). MIPs are similar to subtraction angiograms. Areas of interest are identified by the radiologist and coned down to produce detailed views of the arteries. This post-processing of the images is performed by a technologist. The MIPs are reviewed by the radiologist along with the initial MRA images. The radiologist provides a written interpretation of findings.

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 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.

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

Digital screening mammogram

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.

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.

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.

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.

Abdominal x-ray (single view) [HCPCS 74018]

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.

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.

Hip x-ray of both hips with pelvis (2 views) [HCPCS 73521]

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.

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.

Elbow x-ray (2 views) [HCPCS 73070]

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.

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, 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.

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.

Hand x-ray (2 views) [HCPCS 73120]

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.

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.

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 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-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.

Rib cage x-ray of ribs on one side of body including chest (minimum of 3 views) [HCPCS 71101]

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.

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.

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.

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.

Toe(s) x-ray (minimum of 2 views) [HCPCS 73660]

A radiologic examination of the calcaneus images the bones of the distal lower extremity and usually includes the tibia, fibula, and talus. A radiologic examination of the toe(s) (phalanges) will usually include the metatarsals. 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. 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).

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.

Spinal x-ray of upper spine (2 or 3 views) [HCPCS 72040]

A radiologic exam is done of the cervical spine. Anteroposterior 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.

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.

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.

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.

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.

A diagnostic upper gastrointestinal (UGI) endoscopic examination is performed of the esophagus, stomach, duodenum and/or jejunum with or without collection of specimens by brushing or washing. This procedure may also be referred to as an esophagogastroduodenoscopy (EGD). 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 of the stomach 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. Mucosal surfaces of the duodenum and/or jejunum 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. Cytology samples may be obtained by cell brushing or washing.

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.

Breathing tube insertion into windpipe cartilage with endoscope (emergent) [HCPCS 31500]

The mouth is opened and any dentures are removed. A laryngoscope is passed into the hypopharynx and the glottis and vocal cords are visualized. A properly sized endotracheal tube is selected and the balloon is inflated. A stylet is inserted into the endotracheal tube and the tube and stylet are bent into a crescent shape. The endotracheal tube and stylet are inserted alongside the laryngoscope into the trachea and positioned with the balloon lying just beyond the vocal cords. The stylet is removed and the endotracheal tube is connected to the ventilation device and secured with tape. Breath sounds are checked using a stethoscope to ensure that the endotracheal tube is properly positioned.

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.

Median nerve of hand release and/or relocation (Carpal Tunnel Release) [HCPCS 64721]

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

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.

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.
