CPT code 64892 denotes surgical repair of a peripheral nerve in an arm or leg using a single-strand nerve graft up to 4 cm in length. This procedure is relevant for trauma, reconstructive, and peripheral nerve repair cases and matters nationally because it captures resource use and clinical complexity associated with microsurgical nerve reconstruction. Proper coding affects procedural tracking, clinical outcome measurement, and payer coverage determinations across major insurers.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coding intent and clinical context, typical sites of service, and the common payer landscape. The publication highlights benchmarks and policy-relevant points readers should consider when evaluating coverage and billing for peripheral nerve grafting procedures.

The content provides clinical context for use of CPT code 64892, summarizes what payers typically consider when adjudicating claims for surgical nerve grafts, and points to areas where documentation and procedure detail most influence coding and reimbursement decisions.
