What 26445 covers
Code 26445 represents surgical tenolysis of an extensor tendon in the hand or finger. A hand surgeon may perform it when scar tissue limits tendon glide and active movement, such as after a tendon injury, prior operation, or immobilization. The operative goal is to free the tendon from adhesions while preserving its function; this is different from repairing a torn tendon. The service is commonly performed in an operating room or outpatient surgery setting.
Select this code for the extensor tendon release and site documented in the operative report. Documentation should identify the affected tendon or tendons, the hand or finger location, the adhesions restricting motion, and the release performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in one session, the highest-valued is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is barred by statutory restriction, and co-surgeons and team surgery are not permitted.

How to choose
- 26440Flexor tenolysis
- Choose 26445 for extensor tendon adhesions in the hand or finger; 26440 concerns flexor tendon release in the palm or finger.
- 26449Tendon release
- Both address extensor tendon adhesions, but 26449 is for the forearm or wrist; 26445 is for the hand or finger.
- 26410Hand tendon repair
- Use 26410 when a hand tendon is repaired. Code 26445 describes freeing an extensor tendon restricted by adhesions, not repairing a tendon injury.
