Summary & Overview
CPT 64895: Multiple Strand Nerve Graft for Hand or Foot (Up to 4 cm)
CPT code 64895 represents surgical repair of a hand or foot nerve using a multiple strand (cable) nerve graft up to 4 cm in length. This microsurgical technique is relevant for restoring continuity of peripheral nerves after traumatic or iatrogenic injury and has implications for functional recovery and long-term disability. Nationally, reimbursement and coverage policies for nerve grafting influence access to reconstructive microsurgery and postoperative rehabilitation resources.
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, common sites of service, and where to expect this code to be used. The publication outlines typical billing considerations, common modifiers supplied in the input, and related coding practice points.
This resource provides national-level benchmarks and policy context relevant to providers, coders, and payers: when CPT code 64895 is reported, what clinical scenario it represents, typical settings of care, and how major payers approach coverage. The intent is to clarify coding intent and service context rather than provide clinical guidance. Data not available in the input are identified where relevant.
Billing Code Overview
CPT code 64895 describes repair of a damaged nerve in the hand or foot using a multiple strand nerve graft (a cable-type graft composed of several nerve segments). The graft length for this procedure is up to 4 cm. The service type is surgical nerve grafting.
Typical site of service: operating room or ambulatory surgery center, reflecting a surgical procedure on the hand or foot that requires microsurgical technique and an operative environment.
Data not available in the input for payers, associated taxonomies, and ICD-10 diagnoses.
Clinical & Coding Specifications
Clinical Context
A 34-year-old right-handed construction worker presents after a laceration to the volar aspect of the index finger with loss of sensation and weakness of digital motion. Examination and electrodiagnostic testing localize an injury to a sensory-motor digital nerve with a 2.5 cm nerve gap following debridement. The surgical plan is autologous cable (multiple-strand) nerve grafting of the injured digital nerve to restore continuity and optimize sensory recovery.
Preoperative workflow includes informed consent, evaluation for donor nerve sites (commonly sural or cutaneous branch of the radial nerve), preoperative marking, and anesthesia assessment. In the operating room under regional block or general anesthesia, the surgeon performs exploration and debridement, measures the nerve defect, harvests the donor nerve, constructs a multiple-strand (cable) graft up to 4 cm in length, and microsurgically coapts the grafted strands to the proximal and distal nerve stumps using microsutures and/or fibrin glue. Postoperative workflow includes wound care, immobilization of the hand, referral to hand therapy for sensory re-education, and scheduled follow-up with serial clinical and, if indicated, electrodiagnostic assessment to monitor regeneration.
