Summary & Overview
CPT 64911: Nerve Repair with Autogenous Vein Graft
CPT code 64911 represents surgical repair of a peripheral nerve using an autogenous vein graft harvested from the patient. This technique is used when direct nerve coaptation is not possible and aims to restore continuity and provide a conduit for axonal regeneration. The code is clinically important across specialties that manage traumatic or iatrogenic nerve injuries, including plastic surgery, hand surgery, and peripheral nerve surgery.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a national-oriented account of the clinical context for use of CPT code 64911, typical settings where the procedure is performed, and the types of documentation and procedural descriptors that commonly accompany billing for vein graft nerve repair. The publication outlines benchmarks and coverage considerations where available, highlights relevant coding relationships, and summarizes typical procedural utilization patterns and policy implications for payers and providers. Data not available in the input are noted where applicable.
Billing Code Overview
CPT code 64911 describes surgical repair of a nerve using an autogenous vein graft, a vein harvested from the patient and used to bridge or reconstruct a damaged peripheral nerve. The procedure is a form of nerve grafting performed when primary end-to-end nerve repair is not feasible due to tissue loss or a gap between nerve ends.
-
Service type: Surgical peripheral nerve reconstruction using autogenous vein graft
-
Typical site of service: Operative setting such as an ambulatory surgical center or hospital operating room
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who sustained a traumatic peripheral nerve injury (for example, a segmental injury of the ulnar nerve after a deep laceration to the forearm) where direct end-to-end repair is not possible due to a nerve gap. The patient presents with motor weakness, sensory loss, and positive findings on nerve conduction studies confirming discontinuity or significant segmental loss. The clinical workflow includes preoperative evaluation (history, physical examination, imaging as needed, and electrodiagnostic testing), informed consent discussing nerve grafting options, intraoperative harvest of an autogenous vein (commonly a segment of the saphenous vein or a superficial arm vein), preparation of the vein graft and nerve ends under magnification, microsurgical interposition of the vein graft as a conduit for regenerating axons often with nerve fascicle suturing or placement of nerve autograft within the vein, and postoperative immobilization, pain control, and rehabilitation with serial neurovascular and functional assessments. Typical site of service is an acute care hospital operating room or ambulatory surgical center equipped for microsurgery. Service type is operative microsurgical peripheral nerve repair using an autogenous vein graft (64911).
