Summary & Overview
CPT 26479: Flexor Tendon Shortening, Hand or Finger
CPT code 26479 identifies surgical shortening of a flexor tendon in the hand or finger to address an elongated muscle causing joint instability. This procedure is clinically significant for restoring digital stability and function and is performed by hand surgeons and orthopedic specialists. Nationally, it is relevant for surgical case mix, operative coding accuracy, and appropriate claims adjudication for hand reconstructive procedures.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and common sites of service, payer coverage considerations, and typical coding context. The publication outlines benchmarks for utilization and payment where available, summarizes relevant policy and coverage updates affecting surgical hand procedures, and provides clinical context to help align coding with operative documentation.
This summary is structured to help coding professionals, revenue leaders, and clinical teams understand the service represented by CPT code 26479, its role in hand surgery practice, and the payer landscape relevant to claims processing and policy review. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 26479 describes a surgical procedure in which the provider shortens a flexor tendon of the hand or finger to correct an elongated muscle that is causing joint instability. The procedure is a form of tendon shortening or plication intended to restore functional balance and improve joint stability in the affected digit.
-
Service type: Surgical procedure — tendon repair/shortening
-
Typical site of service: Operative setting such as ambulatory surgical center or hospital operating room
Clinical & Coding Specifications
Clinical Context
A 45-year-old right-hand dominant patient presents with progressive triggering and instability of the proximal interphalangeal joint of the ring finger caused by an elongated or lax flexor tendon resulting in flexion deformity and impaired hand function. Conservative care including splinting, activity modification, and targeted hand therapy did not restore stable joint mechanics. The surgeon plans a surgical flexor tendon shortening of the affected finger to shorten an elongated flexor tendon and restore appropriate tension across the joint.
The clinical workflow includes preoperative evaluation with history and focused hand examination, imaging if indicated (plain radiographs to assess joint alignment), informed consent, operative scheduling with appropriate anesthesia (regional block or general), intraoperative identification of the elongated flexor tendon, measurement and resection or imbrication to achieve appropriate shortening, repair and tensioning, wound closure, sterile dressing, and postoperative hand therapy with staged range-of-motion and strengthening. Typical follow-up visits occur at 10–14 days for wound check, 4–6 weeks for rehabilitation progression, and as needed for functional assessment.
