Summary & Overview
CPT 64896: Multiple Strand Nerve Graft for Hand or Foot Repair
CPT code 64896 identifies a surgical nerve reconstruction using a multiple strand (cable) nerve graft longer than 4 cm to repair damaged nerves of the hand or foot. This procedure addresses challenging segmental nerve defects where direct repair is not possible and has implications for functional recovery of the distal extremity. Nationally, it is relevant across academic centers, community hospitals, and ambulatory surgery centers that provide complex peripheral nerve surgery.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and an overview of coverage considerations with major commercial insurers and Medicare. The publication summarizes common billing and coding characteristics, relevant service-line placement (operative/reconstructive hand and foot surgery), and typical clinical indications for a multiple strand graft when segmental nerve loss exceeds 4 cm.
This summary prepares clinicians, billing staff, and policy stakeholders to understand where CPT code 64896 fits within surgical practice, expected care settings, and payer coverage landscapes. Data not available in the input are identified where applicable elsewhere in the full publication.
Billing Code Overview
CPT code 64896 describes a surgical procedure using a multiple strand nerve graft (a cable-type graft made of several nerve sections) to repair a damaged nerve of the hand or foot when the graft length is greater than 4 cm. The procedure restores continuity of peripheral nerves by bridging a segmental nerve defect with a bundled graft construct.
Service type: Operative peripheral nerve reconstruction
Typical site of service: Hospital operating room or ambulatory surgical center, with post‑operative care typically provided in the same surgical setting or associated outpatient clinic.
Clinical & Coding Specifications
Clinical Context
A 34-year-old right-hand–dominant mechanic sustains a severe laceration to the volar aspect of the wrist and distal forearm after an industrial accident. On exam he has a complete motor and sensory deficit in the distribution of the median nerve distal to the injury with a segmental nerve defect measuring approximately 5.5 cm after debridement. The surgical team performs exploration and debridement in the operating room under general anesthesia, harvests autologous sural nerve segments, constructs a multiple-strand (cable) nerve graft greater than 4 cm in total graft length, and microsurgically coapts the graft to the proximal and distal nerve stumps under loupe or microscope magnification. Typical perioperative workflow includes preoperative consent and marking, intraoperative nerve stimulation and assessment, operative documentation of graft length and number of strands, immediate postoperative neurovascular checks, and planned outpatient follow-up for wound checks and serial motor/sensory evaluation. The typical site of service is an ambulatory surgery center or hospital operating room depending on complexity and patient comorbidities. Ancillary services may include regional block anesthesia, intraoperative nerve monitoring, and postoperative physical therapy and hand therapy for rehabilitation.
