CPT 81001 is used to bill urinalysis to look for cellular material or other substances in a patient’s urine to detect metabolic or kidney disorders.
1. What Is CPT Code 81001?
CPT 81001 covers complete urinalysis and is used to detect cellular material or other substances in the urine that is associated with kidney and metabolic disorders.
A urinalysis is often used for the detection of UTIs (urinary tract infections) or other urinary tract disorders.
The urinalysis, as described by CPT code 81001, includes the following;
- specific gravity;
- clarity; and
This procedure is often performed with a dipstick or a tablet reagent urinalysis. However, other methods are also allowed.

CPT code 81001 is officially described by the CPT book 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; automated, with microscopy.”
As described by CPT 81001, a urinalysis procedure includes a microscopic and macroscopic assessment. The most common methods are;
- chemical evaluation;
- microscopic examination; and
- gross visual assessment of the urine.
A dipstick is most commonly used for the 81001 CPT code procedure. A dipstick analysis is qualitative and semi-quantitative and performed with a color strip for every substance or material that must be detected.
Dipstick tests include;
- specific gravity;
- bilirubin; or
- any number of these constituents.
This procedure is mostly automated. First, the dipstick is dipped in the urine specimen of the patient. Then, the dipstick is put into a spectrum analyzer/colorimeter to read the wavelengths from the colors of the dipstick.
Microscopy involves an examination of urine sediments or solids like abnormal chemical crystals, apart from pus, bacteria, or molds.
4. Billing Guidelines
This procedure takes only 5 minutes if CPT code 81001 is performed with a dipstick and is affordable.
For more specific urinalysis procedural codes with dipstick, see CPT 81000, CPT 81001, CPT 81002, and CPT 81003.
You must include modifier QW (CLIA waived test) in the claim when a lab analyst operates under a CLIA certificate or waiver.
You can not use CPT 81001 for a pregnancy test. Report CPT 81025 instead.
