CPT® Code 27658

The procedure described by CPT® Code 27658 involves the primary repair of a flexor tendon in the leg without the use of a graft. Flexor tendons are critical structures that allow for the movement of the toes and ankle, and they can be damaged due to various injuries such as lacerations, puncture wounds, or closed injuries like avulsions. The flexor muscles and tendons in the lower leg include several key components, such as the peroneus longus, peroneus brevis, plantaris, popliteus, flexor digitorum longus, flexor hallucis longus, and tibialis posterior. When a tendon is completely transected, the surgical procedure involves making an incision over the injury site to access the tendon. The surgeon locates the severed ends of the tendon, which may require manipulation to bring them together for repair. The repair is accomplished through suturing the tendon back together. In cases where the tendon is only partially transected, the procedure focuses on repairing the transected fibers. Additionally, if there is damage to the muscle tissue itself, the muscle is repaired in layers to restore function. This procedure is essential for restoring mobility and function in the affected leg, and it is reported using the code 27658. If the primary repair does not yield satisfactory functional results, a secondary repair may be necessary, which is reported with CPT® Code 27659.
