CPT 64886 Nerve Graft Reimbursement & Policy | OpenPayer

Summary & Overview

CPT 64886: Nerve Graft, Head and Neck, Donor Segment >4 cm

CPT code 64886 denotes an operative nerve graft using a healthy donor nerve segment longer than 4 cm to reconstruct a damaged nerve in the head or neck, restoring sensory and/or motor function after injury or trauma. This reconstructive peripheral nerve surgery is clinically significant because timely and appropriate nerve grafting can affect functional recovery, quality of life, and downstream rehabilitation needs, and it carries implications for surgical resource use and postoperative care.

Key payers addressed in typical coverage and payment discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical indication and service setting, common billing considerations, and the typical modifiers used with this code. The publication explains where CPT code 64886 fits within surgical and reconstruction service lines, summarizes payer coverage relevance at a national level, and outlines what stakeholders should expect when reviewing claims and benefits for head and neck nerve graft procedures.

This summary serves clinicians, coding staff, and payer policy analysts who need a focused clinical and billing context for CPT code 64886, including benchmarks, policy updates, and procedural context. Data not available in the input are noted where applicable.

Billing Code Overview

CPT code 64886 describes a surgical nerve graft procedure in which a healthy nerve segment longer than 4 cm is used to replace a damaged portion of a nerve in the head or neck. The procedure is performed to restore sensory and/or motor function after nerve injury or transection resulting from trauma or surgical complications.

Service Type: Nerve grafting / reconstructive peripheral nerve surgery

Typical Site of Service: Operating room or surgical suite (head and neck surgical setting), with postoperative care provided in an ambulatory surgical center or hospital inpatient/outpatient setting depending on clinical need.

Clinical & Coding Specifications

Clinical Context

A 34-year-old male presents after a motorcycle collision with a complete transection of the facial nerve branch in the parotid/zygomatic region causing loss of motor function to the lower eyelid and upper lip on the right. After imaging and clinical examination confirm a 5 cm segmental nerve loss unsuitable for primary end-to-end repair, the surgical team plans an autologous interposition nerve graft using a healthy donor nerve segment longer than 4 cm to reconstruct the injured facial nerve and restore motor function. The workflow includes preoperative counseling and consent, administration of general anesthesia in an operating room, harvest of an appropriate donor nerve (for example, sural nerve) from the leg, microsurgical preparation and tension-free coaptation of the graft to the proximal and distal stumps under an operating microscope, layered wound closure, postoperative monitoring for bleeding and flap viability, pain control, and scheduled outpatient follow-up with electromyography and rehabilitation for motor reeducation and sensory assessment.
