Summary & Overview
CPT 26426: Central Slip Repair for Boutonniere Deformity
CPT code 26426 describes surgical repair of the central slip of the extensor tendon at the proximal interphalangeal joint to correct a boutonniere deformity and restore finger extension and function. This procedure is an established hand surgery technique with implications for functional recovery, rehabilitation needs, and post‑operative care planning. Nationally, accurate coding of this procedure affects surgical quality measurement, provider reimbursement, and claims adjudication for hand and upper‑extremity services.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and the most relevant billing considerations tied to the code. The publication outlines benchmarks for coding and utilization, summarizes common modifier usage patterns where available, and highlights policy and coverage considerations that influence claim acceptance and prior authorization practices. Clinicians, billing staff, and payor policy analysts will gain a clear understanding of what CPT code 26426 represents clinically and administratively, aiding accurate documentation, coding consistency, and smoother claims processing across major national payers.

Billing Code Overview
CPT code 26426 describes a surgical procedure to repair the central slip of the extensor tendon over the proximal interphalangeal (PIP) joint, commonly performed to correct a boutonniere deformity. The provider manipulates local tissue and repositions lateral bands to restore tendon alignment, and may perform a secondary repair that shortens scar tissue and repairs the tendon to improve finger function and flexibility.
Service type: Hand surgery / tendon repair
Typical site of service: Hospital operating room or outpatient surgical center, frequently performed by orthopedic or hand surgery specialists under regional or local anesthesia with tourniquet control.
Clinical & Coding Specifications
Clinical Context
A 42-year-old right-hand dominant patient presents with a chronic boutonniere deformity of the left ring finger after a zone III extensor tendon injury sustained 9 months earlier. The deformity produces flexion at the proximal interphalangeal (PIP) joint with hyperextension at the distal interphalangeal (DIP) joint and impaired extension of the PIP, limiting activities of daily living and work tasks. Conservative management including splinting and hand therapy failed to restore extensor mechanism continuity and lateral band position. The hand surgeon schedules an operative repair of the central slip (CPT 26426) in an outpatient ambulatory surgery center.
Preoperative workflow includes focused history and physical, assessment of tendon quality and range of motion, informed consent, and marking of the operative finger. Perioperative documentation records the indication (boutonniere deformity), surgical technique (central slip repair with mobilization and repositioning of lateral bands, possible scar excision/shortening), anesthesia type (regional block or general), estimated blood loss, and intraoperative findings. Postoperative workflow includes dressing and splint application to maintain PIP extension, instructions for wound care, hand therapy referral, and scheduled follow-up to monitor tendon healing and range-of-motion recovery.
