Lab analysis of special gram or Giemsa stain to idenitfy microorganisms [HCPCS 87205]

A laboratory test is performed to identify bacteria, fungi, or cell types in pus, normally sterile body fluid(s), or aspirated material using Gram or Giemsa stain technique. Gram staining is a differential technique used to classify bacteria into gram positive (Gram +) or gram negative (Gram -) groups. Gram + bacteria have a thick layer of peptidoglycan in the cell wall which stains purple. Giemsa technique is used in cytogenetics for chromosome staining; in histopathology to detect trichomonas, some spirochetes, protozoans, malaria, and other parasites; and as a stain for peripheral blood and bone marrow to differentiate cells types such as erythrocytes, platelets, lymphocyte cytoplasm, monocyte cytoplasm, and leukocyte nuclear chromatin. A drop of suspended culture or cell material is applied in a thin layer to a slide using an inoculation hook and fixed with heat. The material is stained and the slide is examined under a microscope. The bacteria, fungi, or cells are identified, counted, and a written report of the findings is made.

Lab analysis of stool culture to identify bacteria and additional pathogens [HCPCS 87046]

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 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 blood glucose (sugar) level with hand-held instrument [HCPCS 82962]

A portable testing device called a glucometer is used at the patient's home or a physician's office to monitor glucose levels in the the blood. Glucose is a monosaccharide (single sugar) used for energy by the body. Certain diseases, such as diabetes, and medications may cause glucose levels to be abnormally high or low. A blood sample is obtained by fingerstick and placed on a test strip. Most commercial glucometers use a chemically treated test strip that produces a small electric current when blood is introduced. The strength of the electrical charge is dependent on the level of glucose in the sample. The glucose level is displayed on the monitoring device in a numeric measurement as mg/dL. This code is only reported when the physician or other healthcare professional uses this type of device in the office or other setting to check glucose levels, not when the patient self-administers the test.

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

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

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

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

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

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

Lab analysis to measure red blood cell sedimentation rate to detect inflammation (automated) [HCPCS 85652]

Lab analysis to measure the ammonia level [HCPCS 82140]

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Lab analysis to measure the 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 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.

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 glucose (sugar) level in blood [HCPCS 82947]

A blood sample is obtained to measure total (quantitative) blood glucose level. Glucose is a simple sugar that is the main source of energy for the body. Carbohydrates are broken down into simple sugars, primarily glucose, absorbed by the intestine, and circulated in the blood. Insulin, a hormone produced by the pancreas, regulates glucose level in the blood and transports glucose to cells in other tissues and organs. When more glucose is available in the blood than is required, it is converted to glycogen and stored in the liver or converted to fat and stored in adipose (fat) tissue. If the glucose/insulin metabolic process is working properly, blood glucose will remain at a fairly constant, healthy level. Glucose is measured to determine whether the glucose/insulin metabolic process is functioning properly. It is used to monitor glucose levels and determine whether they are too low (hypoglycemia) or too high (hyperglycemia) as well as test for diabetes and monitor blood sugar control in diabetics.

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.

Liver tissue is tested using quantitative inductively coupled plasma-mass spectrometry.

Lab analysis to measure the lactate dehydrogenase (enzyme) level [HCPCS 83615]

A blood or body fluid test is performed to measure lactate dehydrogenase (LD) (LDH) levels. LDH is an enzyme present in red blood cells (RBCs) and in the tissue of heart, liver, pancreas, kidney, skeletal muscle, brain and lungs. LDH levels are used as a marker for tissue and RBC damage. Elevated blood levels can be caused by stroke, myocardial infarction, liver disease, pancreatitis, muscular dystrophy, infectious mononucleosis, hemolytic anemia and tumors/cancers such as lymphoma. Elevated cerebral spinal fluid (CSF) levels are usually indicative of bacterial meningitis. LDH levels in pleural and/or pericardial fluid can indicate if the effusion is an exudate, caused by an infection or a transudate caused by fluid pressure problem. A blood sample is obtained by separately reportable venipuncture. Cerebral spinal fluid is obtained by separately reportable lumbar puncture (spinal tap). Pericardial fluid is obtained by separately reportable pericardiocentesis. Fluid from a pleural effusion is obtained by separately reportable thoracentesis.

A test on urine is used to measure microalbumin levels and is routinely performed annually on diabetic patients with stable blood glucose levels to assess for early onset nephropathy. The quantitative test, which measures the actual amount of microalbumin present in the urine, may be performed on a random urine sample, with a notation of total volume and voiding time, or a 24-hour urine sample using immunoturbidimetric technique. The semi-quantitative test identifies the presence of elevated microalbumin levels in the urine within a general range and involves a chemical dipstick placed into the urine sample which reacts and changes color when albumin is present.

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

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

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

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

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

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-.

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

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

Abdominal ultrasound (complete) [HCPCS 76700]

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Lab analysis to measure complete blood cell count (red cells, white blood cell, and platelets), automated test [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 albumin, total and direct bilirubin, alkaline phosphatase, total protein, alanine amino transferase, and asparate amino transferase in blood specimen to evaluate liver function [HCPCS 800

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Physical therapy evaluation (typically 30 minutes) [HCPCS 97162]

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

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

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

Elec stim other than wound [HCPCS G0283]

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

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.

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.

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.

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

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

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

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

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

A physical therapy evaluation or re-evaluation is performed. The physical therapist takes a history of the current complaint including onset of symptoms, comorbidities, changes since the onset, treatment received for the symptoms or condition, medications prescribed for it, and any other medications the patient is taking.

CPAP (continuous positive airway pressure) mask or breathing tube initiation and management for night time respiratory muscle rest [HCPCS 94660]

Continuous positive airway pressure (CPAP) ventilation is used primarily to treat sleep apnea. It may also be prescribed to treat preterm infants whose lungs have not fully developed. CPAP uses a mask or other breathing device that fits over the nose and mouth which is connected via a tube to a CPAP device. The CPAP machine delivers an air mixture at a continuous low level of pressure. The continuous positive airway pressure keeps the airways open and prevents mechanical obstruction of the flow of air caused by relaxation and collapse of airway structures during sleep. This code is used for initial set-up and management. A durable medical device provider delivers the CPAP device and other required equipment to the home or a residential facility. The device is set up and programmed to the settings indicated by the written prescription obtained from the physician or other qualified health care professional. The patient or caregiver is instructed on correct use of the CPAP and then is asked to demonstrate understanding by placing the mask over the mouth and nose and turning on the machine.

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.

Collection of blood specimen from arterial puncture for diagnosis [HCPCS 36600]

The radial artery is the most common site for arterial puncture with alternative sites being the axillary and femoral arteries. The arterial puncture site is selected. The skin is prepped for sterile entry. The selected artery is punctured and the necessary blood samples obtained for separately reportable laboratory studies. The needle is withdrawn and pressure applied to the puncture site.

Indwelling bladder catheter insertion (simple) [HCPCS 51702]

A temporary indwelling catheter is inserted into the bladder. This may be referred to as Foley catheterization. A catheter kit is prepared. The urethra is cleansed with antiseptic solution. A sterile Foley catheter is inserted through the urethra into the bladder. The balloon is then inflated with about 10 cc of water to keep it in place. The catheter is attached to a sterile drainage bag and urine is continuously drained from the bladder.

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

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

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

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

Abdominal ultrasound (limited) [HCPCS 76705]

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

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

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

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

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

Arms or legs veins ultrasound with assessment of compression and functional maneuvers (limited, one arm or leg) [HCPCS 93971]

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

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

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

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

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

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.

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.

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

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

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

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

Knee x-ray (3 views) [HCPCS 73562]

A radiologic examination of the knee images the femur, tibia, fibula, patella, and soft tissue. X-ray imaging uses indirect ionizing radiation to take pictures inside the body.

The radiographs may be taken to look for the cause of pain, limping, or swelling, or conditions such as fractures, dislocations, deformities, degenerative disease, osteomyelitis, arthritis, foreign body, and cysts or tumors. Knee x-rays may also be used to determine whether there is satisfactory alignment of lower extremity bones following fracture treatment. Standard views of the knee include front to back anteroposterior (AP), lateral (side), and back to front posteroanterior (PA) with variations in the flexion of the joint, and weight bearing and non-weight bearing postures.

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

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

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

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

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.
