Summary & Overview
CPT 64857: Major Peripheral Nerve Repair of Arm or Leg
CPT code 64857 represents surgical suturing (neurorrhaphy) of a major peripheral nerve in the arm or leg, excluding the sciatic nerve. This code captures a specialized reconstructive nerve repair procedure that can affect functional recovery and long-term disability outcomes for patients with traumatic or iatrogenic nerve injuries. Nationally, accurate coding for major peripheral nerve repair is important for tracking utilization, surgical outcomes, and resource needs in orthopedic and plastic surgery services.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and service settings, commonly applied modifiers and payer considerations (where provided), and what typical claims lines for this procedure represent. The publication summarizes benchmarks and coding guidance where available and highlights policy updates relevant to surgical peripheral nerve repair billing. The content is intended to support revenue cycle, compliance, and clinical teams in understanding how CPT code 64857 is used and where to look for additional payer-specific rules or documentation requirements.

Clinical & Coding Specifications
Clinical Context
A 32-year-old male presents to the emergency department after a deep laceration to the forearm from a kitchen accident. On examination he has loss of motor function of wrist and finger extension and decreased sensation over the dorsal hand consistent with a radial nerve injury. Imaging and neurovascular exam exclude major vascular compromise. The surgical team schedules operative exploration under regional or general anesthesia. Intraoperative findings reveal a transected major peripheral nerve of the arm requiring primary repair. The surgeon performs micro-suturing of the nerve ends with magnification and layered closure. Typical workflow includes preoperative consent, anesthesia evaluation, operative nerve exploration and repair, possible nerve grafting assessment, postoperative immobilization and referral to hand therapy for rehabilitation.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when only the surgeon’s professional work product is billed separately from facility technical service. |
59 | Distinct procedural service | Use when another service normally bundled is performed in a distinct anatomical site or at a separate encounter. |
