CPT Codes For Urinalysis | CPT 81000 – CPT 81099

Urinalysis is a diagnostic test of the urine that detects and diagnoses various diseases and conditions, such as kidney problems, urinary tract infections, diabetes, and more. CPT 81000 until CPT 81099 can be used for different methods of urinalysis and are described below.

What Is Urinalysis?

Urinalysis examines urine to detect and diagnose various diseases and conditions, such as kidney problems, bladder bleeding, urinary tract infections, diabetes, liver disease, and bladder stones.

The tests are typically ordered by the specific analyte being tested and the brand of the product used.

Various methods are used in urinalysis, including quantitative, semi-quantitative, and qualitative methods.

These tests typically use plastic strips containing chemicals that react with the urine and can also screen for pH and specific gravity when dipped into it.

Tablets are also used for urinalysis, where a drop of urine is placed on the tablet, and the color changes due to chemical reactions.

Depending on the method, these diagnostic tests are assigned different CPT codes for urinalysis (81000-81099).

CPT Codes For Urinalysis Description

Urinalysis can be billed with the CPT 81000 until CPT 81099. These methods include microscopy, dipsticks, tablet reagents, quantitative and semi-quantitative analysis, glass tests, and volume measurement.

CPT 81000

81000 covers a non-automated urinalysis that uses dipsticks or tablet reagents to test for bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, and urobilinogen, along with microscopy examination.

TIP: You can find the complete billing guide for CPT code 81000 for non-automated urinalysis with dipsticks and tablet reagents here.

CPT 81001

81001 covers an automated urinalysis with dipsticks or tablet reagents to test for bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, urobilinogen, and microscopy examination.

TIP: You can find the complete billing guide for the CPT code for an automated urinalysis here.

CPT 81002

81002 covers a non-automated urinalysis with dipsticks or tablet reagents to test for bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, urobilinogen without microscopy examination.

CPT 81003

81003 refers to an automated urinalysis with dipsticks or tablet reagents to test for bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, and urobilinogen without microscopy examination.

CPT 81005

81005 describes a qualitative or semiquantitative urinalysis, except for immunoassays.

CPT 81007

81007 covers a screen for bacteriuria in urinalysis, except by culture or dipstick.

CPT 81015

81015 can be used for a urinalysis performed only by microscopy examination.

CPT 81020

81020 refers to a urinalysis performed using two or three glass tests. This method tests urine for pH, specific gravity, and protein.

CPT 81025

81025 describes a urine pregnancy test done using visual color comparison methods. This test detects the presence of human chorionic gonadotropin (hCG), a hormone produced during pregnancy, in the urine.

TIP: You can find the billing guide for CPT code 81025 for the visual color comparison urine pregnancy test here.

CPT 81050

81050 can be used for the measurement of the volume of urine collected over a specific time period, typically 24 hours, known as a timed collection. Each measurement is billed separately.

CPT 81099

81099 refers to an unlisted urinalysis procedure and can be used if any other CPT codes do not describe the procedure for urinalysis.

Examples

The following are examples of when a physician performs urinalysis:

Example 1 

A 60-year-old male patient with a history of COPD, CKD, and a right mid-ureteral stone that required stent placement in November 2022, presents to the hospital with worsening right flank pain for the past six months.

The patient has no other symptoms, such as nausea, headache, vomiting, palpitations, chills, chest pain, or shortness of breath. Dr. El-masry referred him for hospital admission.

He will undergo a retrograde ureterogram, laboratory tests, urinalysis, urine culture, and IV fluids as per the advice of Dr. Javed. The patient has declined pain medication.

Example 2

A 37-year-old male patient with a history of GERD, endometriosis, a previous small bowel resection due to small bowel intussusception in 2014, and diabetes present to the hospital with symptoms of lethargy, vomiting, and abdominal pain.

His blood glucose level was found to be greater than 600 upon arrival. The patient was largely unresponsive during the initial examination, and there is a concern for diabetic ketoacidosis (DKA).

Immediate treatment with fluids, potassium, and insulin was initiated. Due to the patient’s condition, he could not provide a detailed history or review of symptoms.

Example 3

A 52-year-old male patient with a past medical history of a surgical repair for pneumothorax and a history of urinary retention requiring Foley catheterization, but no active medical conditions, presents to the emergency department with worsening urinary symptoms.

He has been experiencing increased urinary frequency, difficulty passing urine, and a sensation of incomplete voiding, which became severe in the past several days.

His wife is concerned about the possibility of prostate enlargement or infection. The patient denies any specific factors that might be causing his symptoms.

He has no fever or chills, no pain while passing urine, no abdominal or flank pain, and no changes in bowel movements.

The results of a urinalysis and urine culture are pending. The urologist has recommended starting treatment with Flomax.
