Summary & Overview
CPT 26437: Extensor Tendon Repositioning to Straighten Fingers
CPT code 26437 designates surgical realignment of an extensor tendon in the hand, reported for each tendon repositioned to restore fingers to a normal, straight position. The procedure addresses finger contractures or deformities often arising from conditions such as arthritis and is relevant to hand surgeons, orthopedic surgeons, and reconstructive specialists. Nationally, this code matters because it captures discrete, tendon-level work and can affect procedural reporting, surgical resource planning, and reimbursement patterns across outpatient surgical settings.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and service settings, common modifiers and billing considerations supplied in the input, and guidance on what to expect when coding this tendon realignment procedure. The publication highlights benchmarking themes, potential policy and coverage implications for surgical hand procedures, and operational factors for facilities and clinicians that report 26437 in ambulatory surgical centers or hospital operating rooms.
This summary is aimed at coding professionals, surgical departments, and policy analysts seeking a national view of how CPT code 26437 is used, documented, and reimbursed within common payer contracts and Medicare policy frameworks.
Billing Code Overview
CPT code 26437 describes a surgical procedure in which a provider repositions an extensor tendon in the hand to return one or more fingers to a normal, straight position. The procedure is used to correct finger deformity when fingers bend abnormally, commonly due to degenerative or inflammatory conditions such as arthritis. The code is reported per tendon realigned.

Clinical & Coding Specifications
Clinical Context
A 68-year-old right-hand–dominant female with long-standing rheumatoid arthritis presents with progressive extension lag and boutonnière-like deformity of the index and middle fingers of the right hand, causing impaired grasp and difficulty performing activities of daily living. Nonoperative management including splinting and corticosteroid injections provided limited relief. After clinical assessment and hand specialist evaluation, the surgeon schedules an operative tendon realignment procedure to reposition the extensor tendons and restore finger alignment. The patient undergoes preoperative clearance, marking of the operative site, and regional or general anesthesia in an ambulatory surgery center or hospital outpatient operating room. The hand surgeon exposes the extensor mechanism, identifies malpositioned tendons, performs direct tendon realignment and repair as needed, and confirms restoration of tendon glide and finger alignment before closure. Postoperative care includes immobilization in a splint, wound checks, staged hand therapy, and follow-up visits to monitor tendon healing and functional recovery. The provider reports 26437 for each individual extensor tendon realigned during the procedure.
