CPT code 81002 is used for non-automated testing of various chemical constituents in a urine sample using dipsticks or tablet reagents. It is often ordered to detect urinary tract infections, evaluate kidney function, and diagnose different medical conditions.
What Is CPT Code 81002
CPT 81002 describes a non-automated urinalysis with dipsticks or tablet reagents to test for various chemical constituents in a urine sample.
The results are read manually from a color chart or by comparing the resulting color to a standard after adding drops of urine to the tablet.
CPT 81002 can test for any constituents, including bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, and urobilinogen.
Urinalysis is often ordered to detect possible urinary tract infections, evaluate kidney function, and diagnose various medical conditions.
The CPT book describes CPT code 81002 as: “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.”
The lab analyst inserts a dipstick into a freshly collected urine specimen, removes the dipstick, and shakes off the excess urine to perform a urinalysis. After the correct reaction time interval, the lab analyst manually reads the results of each analyte from a color chart usually located on the side of the dipstick container, i.e., non-automated.
The analyst reads many of the analytes semiquantitatively, by the plus system, of trace, 1+, 2+, 3+, 4+, or by milligrams per deciliter.
Suppose the analyst uses a tablet reagent instead of the dipstick technique. In that case, he performs that process by placing the tablet on an absorbent pad, dropping the required number of drops of urine on the tablet, and reading the resultant color at a prescribed interval after adding the urine.
How To Use CPT 81002
A single unit of CPT code 81002 represents the analysis of the listed constituents: bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, and urobilinogen.
The lab analyst should examine the urine specimen, especially for the microscopic portion, shortly after collection as cellular elements may change, become distorted, or disappear on standing at room temperature.
CPT 81002 is for the manual method of performing the urine chemical or dipstick portion of the urinalysis. For the automated procedure, see CPT 81003.
