Summary & Overview
CPT 28225: Extensor Tendon Adhesion Release, Foot
CPT code 28225 represents the surgical release of adhesions affecting a single extensor tendon in the foot, a targeted procedure to restore tendon movement and relieve pain from tendonitis or scar formation. Nationally, this code matters because it captures a specific foot tendon surgery distinct from broader tendon procedures, which affects coding specificity, utilization tracking, and coverage determinations across commercial and public payers. Key payers in the scope of national coverage and benchmarking include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of the clinical context for the procedure, commonly reported sites of service, and the types of metrics typically analyzed for this code, including utilization frequency, place-of-service distribution, and payer policy alignment. The content also outlines typical billing considerations such as common modifier use (list provided) and areas where coding specificity affects reimbursement and claims adjudication. If specific comparative benchmarks or local policy variations are relevant, those are presented as national-level observations rather than state-specific guidance. Data not provided in the input — including associated taxonomies, ICD-10 diagnosis pairings, and related codes — are noted as unavailable in the input.
Billing Code Overview
CPT code 28225 describes the surgical removal of adhesions affecting a single extensor tendon in the foot. The procedure is intended to restore tendon gliding, improve range of motion, and reduce pain associated with tendonitis or post-injury scarring.

Clinical & Coding Specifications
Clinical Context
A 48-year-old patient presents to a podiatry clinic with progressive dorsal foot pain, localized swelling over the extensor tendons of the forefoot, and restricted toe extension. Conservative care including NSAIDs, activity modification, and physical therapy for several months failed to relieve symptoms. Clinical exam and dynamic ultrasound demonstrate adhesions tethering a single extensor tendon over the metatarsophalangeal region with limited gliding and focal tendonitis. The patient is scheduled for a surgical release of adhesions under regional or general anesthesia in an ambulatory surgery center. Preoperative steps include informed consent, review of imaging, perioperative antibiotic plan as indicated, and marking the operative site. Intraoperative workflow includes a focused incision over the affected tendon, careful dissection to identify and protect neurovascular structures, adhesiolysis to free the single extensor tendon, hemostasis, and layered closure. Postoperative care includes dressing application, short course of immobilization or a postoperative shoe, instructions for wound care, pain management, and a plan for progressive range-of-motion exercises with follow-up at 1–2 weeks for suture removal and at 6–12 weeks to assess tendon function and pain resolution.
