Summary & Overview
CPT 64712: Open Neurolysis of Sciatic Nerve, Release of Compression
CPT code 64712 represents open surgical neurolysis of the sciatic nerve to release scar tissue or other compressive sources and relieve tension on a major peripheral nerve in the leg. This procedure is clinically significant because sciatic nerve compression can cause severe pain, functional impairment, and prolonged disability; surgical neurolysis is a recognized intervention when conservative care fails. Nationally, accurate coding of nerve decompression procedures influences procedure-level utilization, payment accuracy, and quality measurement for peripheral nerve surgery.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a national view useful to clinicians, billing professionals, and policy analysts on how CPT code 64712 is described, where the service is typically delivered (hospital operating rooms and ambulatory surgery centers), and the clinical rationale for the procedure.
Readers will find a concise clinical context, expected service line and site-of-service details, and guidance on typical documentation elements needed to support billing. Where input data is not provided, the report notes that specific fields are unavailable. The material is intended to support coding accuracy, administrative clarity, and policy understanding related to peripheral nerve neurolysis procedures.
Billing Code Overview
CPT code 64712 describes an open surgical neurolysis of the sciatic nerve, in which the provider incises scar tissue or other compressive structures to relieve pressure and tension on the sciatic nerve. This procedure is intended to restore or improve nerve function and reduce pain caused by entrapment or scarring.
-
Service type: Open peripheral nerve surgery (neurolysis)

Clinical & Coding Specifications
Clinical Context
A 52-year-old patient presents with progressive lateral thigh and posterior leg pain, numbness, and intermittent weakness consistent with sciatic nerve compression after prior gluteal trauma and subsequent scar formation. Conservative management including physical therapy, activity modification, oral analgesics, and epidural steroid injection provided limited relief over 6 months. Imaging (MRI of the pelvis/hip) demonstrates focal scar tissue and entrapment of the proximal sciatic nerve in the gluteal region. The orthopedic or neurosurgical team schedules an open neurolysis of the sciatic nerve (CPT 64712) under general anesthesia in an outpatient ambulatory surgery center. The clinical workflow includes preoperative consent and marking, intraoperative exposure of the sciatic nerve through an open gluteal approach, careful dissection and release of constricting scar tissue or fascial bands, hemostasis, wound closure, postoperative recovery with nerve protection measures, and discharge with instructions for activity limitation and outpatient physical therapy. Typical pre- and postoperative documentation includes neurological exam findings, imaging reports, operative note with laterality, estimated blood loss, and any applicable modifiers (for example LT or RT). Typical site of service is an ambulatory surgery center or hospital outpatient department. Service type is open peripheral nerve surgery (sciatic nerve neurolysis) performed by orthopedic or neurosurgical specialists.
