Summary & Overview
CPT 64898: Multiple Strand Nerve Graft for Peripheral Nerve Repair
CPT code 64898 denotes a multiple strand nerve graft procedure for peripheral nerve repair in an upper or lower extremity when the graft length is greater than 4 cm. This operative code captures a specific reconstructive technique used to bridge substantial nerve defects and is relevant to surgeons, surgical facilities, and payers managing care for traumatic or iatrogenic nerve injuries. Nationally, accurate coding for complex nerve reconstruction supports appropriate coverage determinations and payment for resource-intensive surgical care.
Key payers reviewed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context on when this procedure is used, typical sites of service, and the implications for billing and coverage for lengthy peripheral nerve grafts. The publication presents benchmarks and coding considerations relevant to facility and professional claims, highlights common modifier usage patterns, and summarizes policy language where available.
The article is intended to help coding specialists, surgical teams, and revenue integrity staff understand the clinical scenario captured by CPT code 64898, typical operational settings, and the payer landscape that governs reimbursement and prior authorization practices.
Billing Code Overview
CPT code 64898 describes a multiple strand nerve graft procedure used to repair a damaged peripheral nerve in an arm or leg when the graft length exceeds 4 cm. The technique involves harvesting and implanting one or more nerve graft strands to bridge a nerve defect and restore continuity.
-
Service type: Surgical nerve grafting (peripheral nerve reconstruction)
-
Typical site of service: Hospital operating room or ambulatory surgical center for operative peripheral nerve repair
Clinical & Coding Specifications
Clinical Context
A 32-year-old male motorcyclist presents to the orthopedic surgery service after a high-energy open forearm injury with transection of the median nerve. After initial wound management and imaging in the emergency department, the patient is scheduled for operative exploration. Intraoperative findings confirm a segmental nerve defect of the median nerve measuring greater than 4 cm. The surgeon performs a multiple-strand autologous nerve graft reconstruction using sural nerve segments to bridge the defect. The procedure is performed in an operating room under general anesthesia with regional block for postoperative pain control. Postoperative workflow includes neurovascular checks in the PACU, wound care, immobilization of the limb, and a referral to hand therapy for sensory re-education and motor retraining. Follow-up visits occur at 2 weeks for wound check and at regular intervals (6 weeks, 3 months, 6 months, 12 months) to monitor nerve regeneration and functional recovery. Documentation includes preoperative nerve injury assessment, intraoperative measurements of the graft length (>4 cm), graft source and technique (multiple-strand nerve graft), implant counts if applicable, and detailed postoperative plan including therapy and expected timeline for reinnervation.
