Summary & Overview
CPT 64708: Open Neuroplasty of Major Peripheral Nerve
CPT code 64708 represents an open surgical neuroplasty to release scar tissue or other compressive sources around a major peripheral nerve in an arm or leg at a site not specified by another code. This operative procedure addresses nerve entrapment or tethering that causes pain, dysfunction, or neurologic deficit and is performed by surgeons specializing in peripheral nerve or orthopedic surgery. Nationally, accurate coding for 64708 matters for procedure-level clarity, appropriate claims adjudication, and consistent clinical documentation across settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical intent and typical settings for 64708, plus what to expect in payer coverage discussions and common billing considerations. The publication provides benchmarks for utilization patterns and allowed services where available, highlights relevant policy and coding guidance updates affecting peripheral nerve procedures, and summarizes clinical context to assist payer-policy and revenue cycle stakeholders in interpreting claims for open neuroplasty procedures.

Billing Code Overview
CPT code 64708 describes an open surgical neuroplasty in which the provider incises scar tissue or other sources of compression to relieve tension on a major peripheral nerve in an arm or leg at a location not identified by another CPT code. The procedure targets one of the major peripheral nerves that arise from the spinal nerves and provide motor and sensory innervation to the extremities.
Service type: Open surgical decompression/neuroplasty of a major peripheral nerve
Typical site of service: Operating room or ambulatory surgery center; inpatient surgical setting when clinically indicated
Clinical & Coding Specifications
Clinical Context
A 48-year-old manual laborer presents with progressive numbness, paresthesia, and motor weakness in the forearm and hand after prior trauma with scar formation. Conservative measures including activity modification, splinting, and steroid injection provided incomplete relief. The surgeon evaluates focal neuropathic symptoms localizing to a major peripheral nerve in the arm (e.g., radial or median nerve) at a site not covered by other debridement or decompression CPT codes. Preoperative evaluation includes focused neurologic exam, electrodiagnostic testing (nerve conduction study/EMG), and imaging as indicated (ultrasound or MRI) to define scar-related entrapment. The patient is scheduled for an open release of scar tissue with external neurolysis under regional or general anesthesia in an ambulatory surgery center or hospital operating room. Intraoperative steps typically include identification and protection of the major peripheral nerve, careful dissection and excision of scar or compressive tissue, external neurolysis to relieve tension, hemostasis, and layered wound closure. Postoperative workflow includes immediate recovery, pain control, wound care instructions, occupational/physical therapy referral for range-of-motion and strengthening, and scheduled follow-up with repeat neurologic assessment and, if needed, repeat electrodiagnostic testing to document improvement or persistent deficit.
