CPT code 86038 identifies the technical laboratory procedure to analyze serum for antinuclear antibodies (ANA), a key diagnostic test in the evaluation of autoimmune and rheumatologic disease. Nationally, ANA testing is a common laboratory service with implications for diagnostic pathways, specialty referrals, and downstream care utilization. Accurate coding of the technical component supports appropriate billing, laboratory workflow, and data capture for epidemiology and quality measurement.

This analysis covers major national payers: Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of how CPT code 86038 is defined, the clinical context for ordering the test, typical sites of service where the technical component is performed, and common billing considerations. Where available, benchmark summaries and payer policy highlights are presented to clarify coverage and claim adjudication patterns.

The publication supplies practical reference material for billing and coding staff, laboratory managers, and policy analysts seeking clarity on procedure definition, payer scope, and the clinical role of ANA testing. Data not available in the input is noted explicitly when relevant.
