CPT 81000: Manual Urinalysis with Dipstick and Microscopic Exam
Headline: CPT code 81000: Manual Urinalysis With Dipstick and Microscopy — routine lab test with broad clinical utility
Lead: CPT code 81000 covers a combined manual urinalysis that includes reagent strip or tablet chemical testing and microscopic examination of centrifuged urine sediment. This common laboratory procedure provides rapid, point-in-time information on urine chemistry and cellular elements and is widely used across inpatient and outpatient settings.
CPT code 81000 represents an important frontline diagnostic test used to detect urinary tract infection, hematuria, proteinuria, and other metabolic or renal conditions. Nationally, the code matters because it drives routine lab workflows, billing for basic urinalysis services, and documentation standards in clinical care.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on the clinical context of the test, typical sites of service, and the common billing modifiers associated with laboratory services. The publication outlines what clinicians and billing staff need to know about service definition, typical use cases, and operational considerations for processing specimens and reporting results.
What readers will learn: an overview of CPT code 81000, the clinical and operational scope of the service, payer relevance, and where to locate additional coding guidance. Data not available in the input is noted where applicable.

Billing Code Overview
CPT code 81000 describes a manual urinalysis with both reagent strip/tablet testing and microscopic examination performed by a laboratory analyst. The procedure includes inserting a dip stick into a freshly collected urine specimen or placing drops of urine on a reagent tablet, allowing the appropriate reaction interval, and manually reading one or more analytes against a color chart. The service also includes a microscopic analysis of the sediment, typically performed on a centrifuged specimen using low- and high-power microscopy to report sediment findings.
Service Type: Laboratory — urinalysis, dip stick/chemical and microscopic examination
Typical Site of Service: Clinical laboratory or hospital laboratory (laboratory setting)
