Summary & Overview
CPT 26420: Extensor Tendon Repair of Finger with Free Graft
CPT code 26420 denotes surgical repair of a finger extensor tendon using a free graft, performed as either a primary repair shortly after injury or a secondary repair after delay or prior surgery. This code captures a specialized reconstructive procedure relevant to hand surgery, trauma care, and orthopedic and plastic surgery practices. Nationally, proper coding of this procedure affects surgical quality tracking, reimbursement for complex reconstructive work, and resource planning for operative services.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the code, typical sites of service, and which payers commonly adjudicate claims for this procedure. The publication also summarizes benchmark considerations for providers and payers, highlights policy or coverage factors affecting authorization and payment, and outlines clinical nuances distinguishing primary versus secondary repairs that influence coding and billing.
This summary serves clinicians, coding professionals, and policy analysts seeking a national-level briefing on CPT code 26420, including where the procedure is performed, why it matters for surgical services, and what to expect in payer coverage and administrative workflows. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 26420 describes surgical repair of an extensor tendon of a finger using a free graft, which may be performed as either a primary repair (within a few days of injury) or a secondary repair (performed at least several days after the initial injury or after a prior surgical repair).
Service type: Surgical tendon repair with free grafting.
Typical site of service: Operating room or ambulatory surgery center, with possible associated care in an outpatient surgical clinic for preoperative and postoperative visits.
Clinical & Coding Specifications
Clinical Context
A 34-year-old right-hand dominant male presents 10 days after a laceration to the dorsum of the ring finger sustained while slicing a melon. He reports progressive inability to extend the distal interphalangeal joint and persistent pain. Examination demonstrates a gap in the extensor tendon with weakness of active extension; radiographs show no fracture. After nonoperative measures are unlikely to restore function given the tendon defect and time since injury, the hand surgeon schedules an operative extensor tendon reconstruction using a free tendon graft under regional or general anesthesia. The typical clinical workflow includes preoperative evaluation (history, focused exam, imaging), informed consent documenting primary versus secondary repair timing, operating room procedure involving harvest of a donor tendon graft (commonly palmaris longus or extensor digitorum longus slip), meticulous repair and grafting of the extensor tendon, intraoperative assessment of tendon glide and finger motion, sterile dressing and immobilization, postoperative instructions, and structured hand therapy for tendon healing and mobilization. Typical site of service is an ambulatory surgery center or hospital outpatient operating room. Service type is surgical tendon repair/reconstruction of an upper extremity extensor tendon. Common postoperative care includes wound checks, suture removal, and progressive occupational therapy.

| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the repair requires substantially greater effort, time, or complexity than typical for due to scarring, adhesions, or extensive graft harvest. |
