Summary & Overview
CPT 28234: Extensor Tendon Division of Foot or Toe
CPT code 28234 covers surgical division of an extensor tendon of the foot or toe via a small skin opening to relieve tightness or contracture. This minor soft-tissue surgical code is used for targeted tendon-release procedures that restore range of motion and reduce discomfort. Nationally, accurate coding for such procedures matters for clinical documentation, claims processing, and quality measurement, especially as outpatient and office-based minor surgeries increase.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical intent and common sites of service, plus practical information on how the code fits into billing workflows. The publication outlines typical payer coverage considerations, lists commonly reported modifiers, and situates the code within foot and ankle surgical service lines.
This summary offers clinicians, billing professionals, and policy analysts a clear reference for CPT code 28234, including the clinical scenario it represents, the usual care setting, and the elements they should expect when encountering this procedure in claims and documentation.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting to a podiatry or orthopedic clinic with persistent toe or forefoot pain, limited toe extension, or deformity from an extensor tendon contracture (for example, claw toe or hammer toe with dorsal softtissue tightness). Conservative management (shoe modifications, orthotics, splinting, physical therapy, corticosteroid injection) has failed or symptoms are functionally limiting. After history, focused exam, and review of radiographs to exclude bony deformity or infection, the provider schedules a minor operative procedure in an ambulatory surgery center, hospital outpatient department, or office-based procedure suite.
The procedure involves a small skin incision over the extensor tendon of the affected toe or toes, identification of the tendon, and surgical division (tenotomy or tendon lengthening) to relieve contracture and restore toe alignment and range of motion. Typical perioperative workflow includes preoperative consent, local or regional anesthesia (digital block or popliteal/saphenous block) with or without sedation, sterile prep and drape, the tenotomy/lengthening, hemostasis, and wound closure or dressing. Postoperative instructions address wound care, weight-bearing status, use of protective footwear or orthoses, and follow-up for suture removal and rehabilitation if indicated.
