CPT® Code 28210

The procedure described by CPT® Code 28210 involves the surgical repair of an extensor tendon in the foot using a secondary graft. Extensor tendons are crucial for the movement of the toes and foot, and they include several key muscles such as the tibialis anterior, extensor digitorum, peroneus tertius, and extensor hallucis longus. Injuries to these tendons can occur due to various reasons, including lacerations, puncture wounds, or closed injuries like avulsions, which can lead to partial or complete transection of the tendons. In this procedure, a surgical incision is made over the site of the tendon injury to access the damaged tendon. If the tendon is completely severed, the surgeon locates the ends of the tendon, pulls them together, and repairs them with sutures. In cases of partial transection, the surgeon repairs the damaged fibers directly. If the muscle itself is injured, it is repaired in layers to restore function. For cases requiring a graft, a tendon graft is harvested from another site and attached to the remaining tendon ends, ensuring proper alignment and tension to facilitate movement. The procedure concludes with the closure of the surgical wound in layers and immobilization of the affected area using a splint or cast to promote healing.
