CPT 64910 Nerve Reconstruction Reimbursement | OpenPayer

Summary & Overview

CPT 64910: Nerve Reconstruction Using Conduit or Vein Graft

CPT code 64910 covers surgical nerve reconstruction using an artificial conduit or vein graft to bridge a nerve gap and restore continuity when direct repair is not feasible. This procedure is a specialized microsurgical intervention with implications for functional recovery after traumatic or iatrogenic nerve injuries. Nationally, appropriate use and coverage of nerve grafting procedures affect access to reconstructive surgery and long-term outcomes for patients with peripheral nerve damage.

Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication summarizes coverage patterns, common billing considerations, and the clinical context in which 64910 is used. Readers will find benchmarking information on utilization and reimbursement (where available), an overview of clinical indications and typical care settings, and a concise description of documentation elements that commonly appear in payer policies. The content focuses on national policy and billing practice implications rather than state-specific rules.

The article provides practical context for billing professionals, coding analysts, and surgical teams about where 64910 fits within peripheral nerve repair options, how it is typically performed, and what to expect regarding payer engagement and administrative considerations.

Billing Code Overview

CPT code 64910 describes a surgical procedure in which a provider uses an artificial tube or passageway, or a vein from a living or cadaveric source, to bridge a nerve gap and repair a nerve. This procedure is a form of peripheral nerve reconstruction aimed at restoring continuity of a transected or severely damaged nerve when direct end-to-end repair is not possible.

Service type: Surgical nerve reconstruction using conduit or vein graft
Typical site of service: Operating room or ambulatory surgical center for peripheral nerve repair procedures

Clinical & Coding Specifications

Clinical Context

A 42-year-old male industrial worker presents with a traumatic laceration to the forearm sustained from machinery, resulting in a 3.5-cm gap in the median nerve with loss of motor and sensory function in the hand. After initial wound care and imaging, the surgeon schedules operative nerve reconstruction using a nerve conduit (synthetic tube) or vein graft to bridge the defect and restore continuity. The typical clinical workflow includes preoperative evaluation (history, focused neuromuscular exam, and nerve conduction studies as indicated), informed consent addressing risks and alternatives (including autograft vs conduit/vein graft), intraoperative exploration and measurement of the nerve gap, preparation of the conduit or vein graft, microsurgical nerve coaptation under magnification, and layered wound closure. Postoperative care includes immobilization, analgesia, physical and occupational therapy, and serial clinical and electrodiagnostic follow-up to monitor reinnervation and functional recovery. Typical site of service is the hospital operating room or an ambulatory surgery center for elective reconstruction; this procedure may also occur in a trauma operating room for acute injuries.
