Summary & Overview
CPT 64722: Nerve Decompression, Release of Constricting Ligaments
CPT code 64722 covers surgical decompression of an unspecified peripheral nerve by releasing constricting ligaments. This procedure is a targeted surgical intervention to relieve nerve compression and can affect pain, motor function, or sensory deficits depending on the nerve involved. Nationally, accurate coding of nerve decompression procedures supports appropriate clinical tracking, quality measurement, and payment for operative care.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for when decompression is performed, expected sites of service, and typical billing considerations. The publication presents national benchmarks for utilization and reimbursement where available, summarizes relevant policy updates affecting coverage and medical necessity determinations, and outlines documentation elements important for code selection and claim adjudication.
The content is intended for clinicians, billing and coding professionals, and policy analysts seeking concise guidance about the clinical and administrative implications of reporting CPT code 64722 for nerve decompression procedures.
Billing Code Overview
CPT code 64722 describes a surgical decompression of an unspecified peripheral nerve, in which the provider frees the nerve from surrounding ligaments that are exerting pressure. The documentation must specify which nerve was decompressed.
-
Service type: Surgical nerve decompression
-
Typical site of service: Hospital outpatient department or ambulatory surgery center; may also be performed in an inpatient setting when clinically indicated
Clinical & Coding Specifications
Clinical Context
A 52-year-old patient presents with focal forearm pain, numbness, and motor weakness consistent with entrapment neuropathy of a peripheral nerve (for example, ulnar nerve compression at the elbow or radial tunnel syndrome). Conservative care including activity modification, splinting, anti-inflammatory medications, and targeted physical therapy has failed after a trial of several months. Diagnostic testing such as nerve conduction studies and electromyography confirms slowed conduction across an anatomic constriction. The surgeon schedules an operative decompression under regional block or general anesthesia in an ambulatory surgery center or hospital outpatient department. Intraoperative steps include incision, identification of the affected nerve, careful dissection to release constricting ligaments and fibrous bands, confirmation of free nerve glide, hemostasis, and layered wound closure. Typical workflow includes preoperative consent and documentation of the specific nerve decompressed, anesthesia record, operative note specifying technique and laterality, and postoperative instructions for wound care and activity restrictions. Postoperative follow-up assesses sensory and motor recovery and documents any complications or need for further intervention.

26 | Professional component | Use when reporting only the physician’s professional portion of a service when a distinct technical component exists (rare for simple decompression but applicable when global services are split). |
