CPT® Code 81002

Urinalysis, by dip stick or tablet reagent for bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, urobilinogen, any number of these constituents; non-automated, without microscopy

A urinalysis is a diagnostic procedure that involves the examination of urine to assess various health conditions. This specific test, identified by CPT® Code 81002, utilizes dip stick or tablet reagent methods to analyze constituents such as bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, and urobilinogen. The procedure is non-automated and does not include microscopy. The dip stick method employs a paper or plastic stick with color strips that react to the presence of specific substances in the urine. When the stick is immersed in the urine sample, the color changes on the strips are compared to a standard color chart to determine the presence or concentration of the tested agents. Alternatively, the tablet reagent method involves placing a few drops of urine on an absorbent mat, followed by the addition of a reagent tablet and distilled water, allowing for observation of color changes that indicate the presence of various substances. The analysis of these constituents can provide critical insights into a patient's health, as certain abnormalities can indicate underlying conditions such as diabetes mellitus, kidney disease, or urinary tract infections. For instance, the presence of glucose in the urine may suggest diabetes, while elevated protein levels could indicate nephrotic syndrome. The test is valuable for its ability to quickly screen for conditions that may not present immediate symptoms, making it an essential tool in clinical diagnostics. It is important to note that while this procedure does not include microscopy, further examination of the urine sample under a microscope may be warranted in certain cases, which would require the use of different CPT® codes for billing purposes.
