Summary & Overview
CPT 26476: Extensor Tendon Lengthening of Hand or Finger
CPT code 26476 designates a surgical tendon-lengthening procedure performed on the extensor tendon of a hand or finger to address muscle contracture and improve joint mobility. This code is important nationally because it captures a targeted hand surgery intervention commonly used to treat contractures from trauma, tendon imbalance, or neuromuscular conditions. Accurate use of the code affects clinical documentation, surgical workflow classification, and payment for hand and orthopedic surgical services across payers.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, the typical site of service, and the types of information payers review when adjudicating claims for tendon-lengthening surgeries. The publication provides benchmarks for coding and billing practices, summarizes relevant policy considerations that influence coverage and prior authorization, and outlines documentation elements commonly required for medical necessity determinations.
The content equips administrators, coding professionals, and clinicians with an overview of when to use CPT code 26476, what clinical situation it represents, and what to expect from major commercial and public payers in terms of coverage and review. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 26476 describes a surgical procedure to lengthen the extensor tendon of a hand or finger to treat muscle contracture. This procedure involves surgically releasing or lengthening the tendon to improve range of motion and reduce fixed flexion deformity.
-
Service type: Surgical procedure (hand/finger tendon lengthening)
-
Typical site of service: Ambulatory surgery center or hospital operating room
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a progressive extensor tendon contracture of a finger or hand resulting in limited extension, pain, and functional impairment. The patient often presents to a hand surgery clinic after conservative measures (splinting, occupational therapy, corticosteroid injections) have failed. Evaluation includes history, physical exam documenting fixed flexion deformity or decreased active extension, and imaging if joint or bony pathology is suspected. The hand surgeon obtains informed consent, reviews risks (infection, stiffness, tendon rupture, neurovascular injury), and schedules operative hand or ambulatory surgery center (ASC) time. In the operating room or ASC, under regional block or general anesthesia, the surgeon performs lengthening of the extensor tendon (proximally, distally, or at the musculotendinous junction) to restore functional extension. Postoperative care includes wound checks, analgesia, hand therapy, and instructions for activity modification. Typical sites of service are the hospital outpatient department or ambulatory surgery center, and occasionally an inpatient setting for complex cases or comorbidities.
