CPT® Code 27659

The procedure described by CPT® Code 27659 involves the secondary repair of flexor tendons in the leg, which are crucial for the movement and function of the ankle and toes. Flexor tendons are responsible for bending the toes and facilitating various movements of the foot. Common flexor tendons in the lower leg include the peroneus longus, peroneus brevis, plantaris, popliteus, flexor digitorum longus, flexor hallucis longus, and tibialis posterior. Injuries to these tendons can occur due to lacerations, puncture wounds, or closed injuries such as avulsions, leading to partial or complete transection of the tendons. The surgical procedure begins with an incision over the site of the injury, allowing the surgeon to access the affected tendon. If the tendon is completely severed, the ends are located and sutured together. In cases of partial transection, the surgeon repairs the damaged fibers. If the muscle itself is involved, it is repaired in layers to restore function. If the initial repair does not yield satisfactory functional results, a secondary repair may be necessary, which can involve the use of a graft. This process includes harvesting a tendon graft, attaching it to the remnants of the severed tendon, and ensuring proper tension and range of motion before closing the surgical site. The leg and ankle are then immobilized to promote healing.
