Summary & Overview
CPT 64702: Digital Nerve Decompression, Open Release
CPT code 64702 represents an open digital nerve decompression procedure for a single finger or toe, used to incise scar tissue or other compressive sources to relieve tension on one or both digital nerves. This procedure addresses sensory nerve compression at the digit level and is performed by hand or podiatric surgeons in operative settings. Nationally, accurate coding of 64702 matters for appropriate clinical documentation, correct surgical classification, and payment alignment across commercial and public payers.
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 context for the code, typical sites of service, and the common modifiers associated with procedural billing. The publication provides operational benchmarks and coding practice considerations relevant to orthopedic, hand, and podiatric service lines, and outlines where policy updates and payer-specific coverage language typically influence reimbursement and prior authorization requirements.
This summary equips clinicians, coding professionals, and revenue cycle teams with the clinical framing and billing scope for 64702, enabling clearer communication with payers and improved claims accuracy.
Billing Code Overview
CPT code 64702 describes an open surgical procedure to relieve pressure on one or both digital nerves of a single finger or toe by incising scar tissue or other compressive structures. Digital nerves are the sensory nerves that run along each side of a finger or toe and provide sensation to the digit.
Service Type: Digital nerve decompression (open release)
Typical Site of Service: Ambulatory surgical center or hospital operating room; procedure performed on a finger or toe

Clinical & Coding Specifications
Clinical Context
A middle-aged patient presents with progressive numbness and paresthesia along the radial or ulnar side of a single finger after prior laceration and scar formation near the digital neurovascular bundle. Conservative care (activity modification, splinting, and local steroid injection) failed to improve persistent sensory disturbance and painful scar tethering. Physical exam demonstrates point tenderness and Tinel-like reproduction at the level of the scar with sensory loss in the digital nerve distribution. The surgeon schedules an open procedure to release scar tissue compressing the digital nerve in a single finger, performed in an outpatient ambulatory surgery center or hospital minor operating room under regional block or local anesthesia with/without sedation. The workflow includes preoperative consent and marking, sterile preparation, targeted incision over the scar or site of entrapment, careful dissection to identify and neurolyse the digital nerve(s), scar excision or internal neurolysis as needed to relieve tension, hemostasis, layered closure, and a postoperative dressing with instructions for wound care and sensory monitoring. Typical immediate postoperative documentation includes the procedure performed, laterality and finger identified, anesthesia type, estimated blood loss (usually minimal), findings (scar tethering and decompressed digital nerve), and postoperative plan for wound checks and therapy if indicated.
