CPT 87902: Hepatitis C Genotype by Nucleic Acid, Technical Component

CPT code 87902 represents the technical laboratory component of a molecular diagnostic assay to determine the specific genotype of hepatitis C virus (HCV) from a patient specimen. Nationally, genotype determination guides clinical management of HCV, influences antiviral selection, and supports public health surveillance, making accurate billing and coding for this test important for clinical workflows and laboratory reimbursement.

This analysis covers major national payers including Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for HCV genotyping, typical sites where the service is performed, commonly applied billing modifiers, and what to expect in payer coverage approaches. The publication summarizes available benchmarks and policy considerations, highlights coding definitions and service characterization, and notes where input data are unavailable.

Intended for laboratory managers, medical coders, and health policy analysts, the content clarifies the role of CPT code 87902 in laboratory billing for HCV genotype testing and outlines the practical implications for billing workflows and payer interactions at a national level.

Clinical & Coding Specifications

Clinical Context

A 48-year-old patient with known chronic hepatitis C infection presents for genotype testing to guide antiviral therapy selection. The clinician collects a peripheral blood specimen (serum or plasma) which is sent to the molecular diagnostics laboratory. The laboratory analyst performs nucleic acid-based testing to determine the hepatitis C virus (HCV) genotype and subgenotype using validated molecular methods (for example, RT-PCR with sequencing or genotype-specific probes). Results are reported to the ordering provider and entered into the electronic medical record to inform direct-acting antiviral regimen choice and duration. Typical site of service is an independent clinical laboratory, hospital outpatient laboratory, or reference laboratory performing specialized molecular diagnostics.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when billing only the professional (interpretation) component separate from the technical component.
`TC`	Technical component	Use when billing only the technical component (laboratory testing, equipment, reagents).
`90`	Reference laboratory	Use when the service is performed by a qualified outside laboratory.
`91`	Repeat clinical diagnostic laboratory test	Use when the same test is repeated on the same day to obtain subsequent (non-qualitative) results.
`59`	Distinct procedural service	Use when a distinct service or procedure not normally reported together is performed on the same day (rare for this single assay).
`62`	Two surgeons (or two practitioners)	Use if two qualified laboratory directors/shared responsibilities require split services (uncommon).
`80`	Assistant surgeon	Not typically applicable; included when an assisting laboratory professional is separately reportable.
`90`	Reference laboratory	Use when the testing is sent to an outside reference laboratory for performance and reporting.
`91`	Repeat clinical diagnostic laboratory test	Use when repeated for verification or quality control on the same patient sample.
`QK`	Clinical laboratory improvement amendments (CLIA) waived testing	Use when applicable to designate testing under specific arrangements (limited applicability).
`QY`	Laboratory services furnished under a CLIA waiver by a laboratory improvement program	Use only when regulatory conditions apply.
