CPT 86813: HLA Class I Serologic Antigen Typing
CPT code 86813 represents serologic testing for multiple human leukocyte antigens (HLA) within HLA Class I (A, B, and C) and is used to identify antigen specificities for clinical and transplant-related decision-making. Nationally, HLA typing supports organ and tissue matching, transfusion planning, and certain immunogenetics evaluations; accurate coding ensures appropriate laboratory claims and downstream clinical workflows. This publication covers commercial and government payers commonly involved in laboratory reimbursement: Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise explanation of what CPT code 86813 denotes, typical settings where the service is performed, and the clinical relevance of HLA Class I serologic assays. The analysis highlights payer coverage considerations and common modifiers encountered on laboratory claims. It also outlines benchmarks and policy developments relevant to HLA testing reimbursement and situates CPT code 86813 in the broader laboratory service line context.
