Summary & Overview
CPT 25116: Open Excision Around Extensor Tendons
CPT code 25116 defines an open wrist procedure for extensive excision of diseased structures around the extensor tendons. This operative hand/wrist code captures surgical management for conditions that involve widespread pathology adjacent to extensor tendons, such as severe tenosynovitis, chronic inflammatory disease, or destructive degenerative processes. As an operative code, it has implications for surgical setting utilization, facility payments, and clinician billing practices nationally.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a clinical context for when CPT code 25116 is used, typical sites of service, and the types of surgical interventions it represents. The publication also summarizes benchmarking considerations and common billing modifiers and payer coverage patterns where available.
This analysis is intended to inform billing staff, surgical providers, and policy analysts about the code’s clinical scope, service line placement, and national payer relevance. Data not available in the input is explicitly noted and not fabricated.
Billing Code Overview
CPT code 25116 describes an open surgical procedure on the wrist in which the provider performs extensive excision of diseased structures surrounding the extensor tendons. The procedure involves opening the wrist joint and removing pathologic tissue that is spread around the extensor tendons to relieve pain, restore function, or manage chronic inflammatory or degenerative conditions.
-
Service type: Operative hand/wrist procedure (open excision around extensor tendons)
-
Typical site of service: Hospital operating room or ambulatory surgery center (open wrist surgery)
Clinical & Coding Specifications
Clinical Context
A 58-year-old right-hand-dominant patient presents with progressive dorsal wrist pain, swelling, and triggering near the extensor tendons after conservative care (immobilization, NSAIDs, and corticosteroid injection) failed. Examination shows focal tenderness over the dorsal wrist and restricted range of motion with crepitus over the extensor compartments. Imaging (wrist radiographs and ultrasound or MRI) demonstrates tenosynovial hypertrophy and synovial proliferation around the extensor tendons consistent with chronic tenosynovitis or extensor compartment disease. The patient is scheduled for open dorsal wrist exploration with extensive excision of inflamed synovium and diseased tissue adjacent to the extensor tendons to relieve pain, restore tendon gliding, and prevent tendon attrition.
The clinical workflow includes preoperative evaluation by the hand surgeon, informed consent detailing risks and benefits, anesthesia clearance (regional block or general anesthesia), operative dorsal incision over the wrist, exposure of the extensor retinaculum and tendon sheaths, careful excision of hypertrophic synovium and diseased tissue surrounding the extensor tendons, hemostasis, possible repair or release of retinacular structures if indicated, layered wound closure, and postoperative immobilization with a splint. Typical follow-up includes wound check at 10–14 days and staged hand therapy to restore motion and strength.
