CPT® Code 26556

A free toe joint transfer, as described by CPT® Code 26556, is a surgical procedure aimed at reconstructing an injured finger joint. This complex operation involves the transfer of a joint from the toe to the finger, which is particularly useful in cases where the finger joint has been severely damaged or is non-functional. The procedure can be performed on different joints of the finger, specifically the metacarpophalangeal joint or the proximal interphalangeal joint, depending on the specific needs of the patient. During the operation, the surgeon meticulously prepares the finger by excising the damaged joint structures while ensuring that the blood vessels supplying the joint are carefully isolated and preserved to maintain blood flow. To facilitate the transfer, a dorsal pedicle flap is created at the toe joint, which involves careful dissection to keep the blood vessels intact. The joint structures are then harvested, ensuring that the blood supply to the dorsal flap remains undisturbed. Once the toe joint is successfully transferred to the finger, the surgeon performs microvascular anastomosis to connect the blood vessels, which is crucial for the viability of the transferred joint. After the transfer, the soft tissues overlying the joint are closed in layers to promote healing. To stabilize the transferred joint in the finger, a Kirschner wire is used, while the surgical site on the toe is also repaired, with additional Kirschner wires employed to stabilize the toe until proper healing and osteosynthesis occur. This procedure is essential for restoring function and mobility to the finger following significant injury or trauma.
