CPT 64834 Sensory Nerve Repair Reimbursement

CPT code 64834 represents surgical repair of a sensory nerve in the hand or foot to restore sensory function following injury or trauma. This procedure is clinically important because restoration of sensation can reduce long-term disability, improve functional hand or foot use, and potentially decrease downstream complications such as chronic neuropathic pain or impaired wound healing. Nationally, surgical peripheral nerve repairs are performed across inpatient and outpatient surgical settings and are relevant to trauma, orthopedics, and hand surgery workflows.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a practical overview of clinical indications and typical sites of service, and summarizes commonly observed billing considerations. Readers will find benchmarking context for utilization and payment where available, a concise explanation of clinical intent, and notes on common modifiers and administrative issues to expect in claims processing. The report is designed for billing managers, surgical coders, practice administrators, and policy analysts seeking a national perspective on coding, clinical context, and payer coverage patterns for CPT code 64834.

Billing Code Overview

CPT code 64834 describes surgical repair of a sensory nerve in the hand or foot to restore sensory function after injury or trauma. The procedure is focused on reestablishing continuity of injured or severed sensory nerves to improve or recover sensation in the affected extremity.

Service type: Surgical repair of peripheral sensory nerve
Typical site of service: Hospital operating room or ambulatory surgery center for hand or foot procedures

Clinical Context

A 32-year-old right-hand dominant construction worker presents after a deep laceration to the volar aspect of the index finger sustained from a circular saw. On exam there is loss of light touch along the radial digital nerve distribution of the index finger and a clean, sharp transection of a sensory nerve stump visualized at the wound. The patient is taken to the ambulatory surgery center for urgent microsurgical repair under regional block. The clinical workflow includes preoperative evaluation and consent, pre-op marking of the injured sensory nerve, administration of anesthesia (axillary block or local/regional), operative exploration and identification of the proximal and distal sensory nerve ends, microsurgical epineurial repair with magnification and fine sutures, wound closure, sterile dressing, and postoperative hand therapy referral and follow-up for wound check and sensory recovery assessment.
