CPT® Code 28220

Tenolysis is a surgical procedure aimed at freeing a tendon from the surrounding tissue that may be restricting its movement. Specifically, CPT® Code 28220 refers to the tenolysis of a single flexor tendon in the foot. This procedure is typically indicated when scar tissue has formed around the tendon due to trauma or a disease process, which can impede the normal motion of the foot and toes. The goal of the procedure is to restore mobility by carefully releasing the adhesions that have developed around the tendon. During the operation, a surgical incision is made directly over the affected tendon, allowing the surgeon to access the area. The surrounding soft tissues are meticulously dissected to expose the tendon, which is then identified. Once located, the surgeon will sever the adhesions that are binding the tendon, thereby restoring its function. After the tenolysis is completed, the range of motion of the tendon is evaluated to ensure that the procedure has been successful. Finally, the surgical wound is closed in layers, and a dressing is applied to protect the area as it heals. This procedure is crucial for patients who have experienced limited mobility due to tendon adhesions, and it is important to note that a similar procedure for multiple flexor tendons is coded under CPT® Code 28222.
