Summary & Overview
CPT 64874: Peripheral Nerve Mobilization and Repositioning Repair
CPT code 64874 covers surgical mobilization or repositioning of a peripheral nerve when the nerve is too short to be repaired without tension, performed to restore sensory and/or motor function after traumatic injury. The code captures a specific technique—freeing the nerve from its bed or advancing it into a new position—distinct from grafting or direct end-to-end neurorrhaphy. Nationally, this procedure matters for trauma care pathways, limb-salvage surgeries, and functional restoration programs, with implications for surgical resource use, postoperative rehabilitation, and payer authorization policies.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when 64874 is used, typical sites of service, and how this service fits into broader nerve repair care. The publication also highlights common billing and coding considerations, benchmark expectations where available, and relevant policy or coverage themes that affect authorization and reimbursement. Data not provided in the input—such as associated taxonomies, ICD-10 mappings, and payer-specific rate benchmarks—are noted as unavailable and are not fabricated here.
Billing Code Overview
CPT code 64874 describes surgical repair of a nerve that is too short to be reapproximated without tension by freeing the nerve from its bed or repositioning it within the bed. This procedure is performed to restore sensory and/or motor function after nerves are damaged or severed by injury or trauma.
-
Service type: Peripheral nerve repair involving mobilization or advancement of the nerve to achieve a tension-free repair.
-
Typical site of service: Hospital operating room or ambulatory surgical center, frequently performed by orthopedic or plastic surgeons, neurosurgeons, or peripheral nerve specialists following traumatic nerve injury.
Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who sustained a traumatic laceration or crush injury to an upper extremity (commonly hand, wrist, or forearm) with partial nerve loss and a nerve gap that prevents tension-free end-to-end repair. The patient presents to the emergency department or an outpatient hand surgery clinic with sensory loss, motor weakness, and neuropathic pain localized to the affected nerve distribution. Initial evaluation includes history, focused physical and neurologic exam, and imaging as needed (plain radiographs to assess associated fractures, ultrasound or MRI neurography if available). Nerve conduction studies or electromyography may be deferred acutely but used later for surgical planning.
The clinical workflow: the patient undergoes preoperative assessment and informed consent. In the operating room under regional or general anesthesia, the surgeon explores the injured nerve, debrides nonviable segments, and determines that the nerve cannot be approximated without tension. The surgeon performs a nerve transposition or frees the nerve within its bed and repositions it to achieve a tension-free repair (CPT 64874). Hemostasis, layered closure, and immobilization follow. Postoperative care includes wound checks, immobilization, pain control, early hand therapy, and serial neurologic assessments. Rehabilitation focuses on sensory re-education and motor strengthening; follow-up EMG may assess reinnervation over months.
