CPT® Code 27664

The procedure described by CPT® Code 27664 involves the primary repair of an extensor tendon in the leg, specifically without the use of a graft. Extensor tendons are crucial for the movement of the toes and ankle, and they include the tibialis anterior, extensor digitorum, peroneus tertius, and extensor hallucis longus. Injuries to these tendons can occur due to various reasons, such as lacerations, puncture wounds, or closed injuries like avulsions, which can lead to partial or complete transection of the tendons. During the repair procedure, a surgical incision is made at the site of the tendon or muscle injury. If the tendon is completely severed, the surgeon locates the ends of the tendon, pulls them together, and sutures them to restore continuity. In cases of partial transection, the surgeon repairs the damaged fibers directly. If the muscle itself is involved, it is repaired in layers to ensure proper healing. This procedure is essential for restoring function and mobility in the affected leg. If the primary repair does not yield satisfactory functional results, a secondary repair may be necessary, which can involve additional techniques or the use of grafts. The surgical site is then closed in layers, and the leg and ankle are immobilized to promote healing.
