CPT® Code 27686

The procedure described by CPT® Code 27686 involves the surgical lengthening or shortening of multiple tendons in the leg or ankle, performed through a single incision. This intervention is typically indicated for correcting flexion or extension deformities of the ankle, which may arise from various conditions, including the late effects of injuries or chronic diseases such as severe rheumatoid arthritis or osteoarthritis. The surgical approach begins with making a skin incision over the targeted tendon, followed by careful dissection of the surrounding soft tissues to expose the tendon. For lengthening, a Z-shaped incision is created in the tendon, allowing the tendon fibers to separate and elongate as the ankle is flexed or extended. This technique is crucial for restoring proper function and alignment of the ankle. Conversely, if shortening is required, the tendon is divided, and the ends are overlapped and sutured together to achieve the desired length. Post-surgery, the ankle is immobilized in a splint or cast to ensure stability and promote healing. It is important to note that CPT® Code 27686 is specifically used for procedures involving multiple tendons, while CPT® Code 27685 is designated for the lengthening or shortening of a single tendon in the leg or ankle.
