CPT code 64802 covers surgical destruction or removal of a portion of the cervical sympathetic nerve to relieve pain or improve blood flow in patients with compromised vascular supply. The procedure is clinically significant for management of refractory neuropathic pain and certain vasospastic conditions where interruption of sympathetic input can reduce symptoms and enhance perfusion. Nationally, accurate coding for this specialized nerve procedure affects procedural reporting, facility planning, and appropriate payer adjudication.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a synthesis of clinical context for the procedure, typical sites of service, and the operational considerations that influence billing and coverage. The publication outlines benchmarks and common billing modifiers used in practice, highlights payer coverage patterns where available, and summarizes relevant policy considerations that influence reimbursement and prior authorization practices.

This analysis provides clinicians, coders, and policy stakeholders with concise guidance on the clinical purpose of CPT code 64802, the care settings where it is performed, and the payer landscape to inform documentation and claims workflows.
