CPT 83582: Urine Ketogenic Steroid Fractions for Adrenal Function

CPT code 83582 describes a laboratory assay measuring ketogenic steroid fractions in a 24–hour urine specimen to evaluate adrenal function. Nationally, this code is used in endocrine and metabolic workups when clinicians need detailed assessment of adrenal steroidogenesis and cortisol metabolites. Accurate reporting of 83582 supports proper clinical interpretation, claims processing, and epidemiologic tracking of adrenal diagnostic testing.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines coverage and billing considerations relevant to commercial and public payers, noting common coding contexts and laboratory service settings. It summarizes payer coverage patterns where available and highlights areas where policy language or prior authorization criteria may affect utilization.

Readers will find a concise clinical context for the test, typical settings for specimen collection and analysis, and an overview of what to expect in payer interactions. The report also identifies benchmarking elements and policy updates that influence billing and reimbursement workflows. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 83582 measures ketogenic steroid fractions in a urine specimen, typically collected over a 24–hour period, to assess adrenal function. This laboratory procedure quantifies specific steroid metabolites that help evaluate adrenal steroidogenesis and cortisol metabolism.

Service type: Laboratory diagnostic test (urine steroid metabolite analysis)
Typical site of service: Clinical laboratory or hospital laboratory; specimen collected in outpatient or ambulatory settings for send-out or in-house testing.

Data not available in the input.

Clinical & Coding Specifications

Clinical Context

A 42-year-old patient with persistent hypertension, unexplained weight loss, and episodes of weakness is referred for endocrine evaluation to assess adrenal cortical function. The clinician suspects hypercortisolism or adrenal steroid metabolism disorders and orders a 24-hour urine collection for measurement of ketogenic steroid fractions to quantify adrenal steroid metabolites.

The typical clinical workflow: the patient receives collection instructions and a 24-hour urine container at the outpatient phlebotomy or laboratory collection site. The full 24-hour specimen is returned to the clinical laboratory. A certified medical technologist or clinical chemist processes the specimen, performs extraction and chromatographic separation, and measures ketogenic steroid fractions (commonly via gas chromatography–mass spectrometry or liquid chromatography–mass spectrometry). Results are reported to the ordering endocrinologist or primary care provider, who integrates the steroid profile with serum studies and imaging to guide diagnosis and management of adrenal disorders.

Coding Specifications

Modifier	Description	When to Use

`TC`	Technical component	Use when billing only the technical component (laboratory performance) of the test.
`90`	Reference (outside) laboratory	Use when the test is performed by an outside or reference laboratory and the ordering facility bills for the service.
`52`	Reduced services	Use when a specimen is incomplete or testing is partially limited and a reduced service is billed.
`53`	Discontinued procedure	Use when collection or testing is started but discontinued for patient safety or specimen issues.
`59`	Distinct procedural service	Not in provided list; omitted.
`91`	Repeat clinical diagnostic laboratory test	Not in provided list; omitted.
`90`	Duplicate - already listed above	Duplicate entries are omitted.
`22`	Increased procedural services	Use when test complexity or interpretive effort is substantially greater than typical and requires additional documentation.
