CPT® Code 26553

1. Indications

The procedure described by CPT® Code 26553 is indicated for the following conditions:

• Loss of Finger Function Patients who have lost a finger due to trauma, disease, or congenital anomalies may benefit from a toe-to-hand transfer to restore functionality.
• Reconstruction Needs Individuals requiring reconstruction of the hand for aesthetic or functional purposes, particularly when traditional methods are not viable, may be candidates for this procedure.
• Severe Hand Deformities Patients with severe deformities or deficiencies in the hand may require this transfer to improve hand function and appearance.

2. Procedure

The procedure for a toe-to-hand transfer using CPT® Code 26553 involves several detailed steps:

• Preparation of the Hand The surgical team begins by preparing the hand to receive the toe transfer. This includes making an incision at the recipient site and excising any scar tissue that may impede the transfer.
• Bone Stump Preparation The bone stump at the recipient site is carefully prepared to ensure a proper fit for the transferred toe.
• Tissue Dissection The tissues of the hand are meticulously dissected to identify and isolate the extensor and flexor tendons, as well as the nerve ends that will be involved in the anastomosis.
• Identification of Blood Vessels Blood vessels in the hand are located and prepared for anastomosis, which is crucial for restoring blood flow to the transferred toe.
• Incision and Flap Elevation Incision lines are outlined on the skin around the toe designated for transfer. A dermal flap is then elevated, ensuring the preservation of the dorsalis pedis artery and a large subcutaneous dorsal vein for the microvascular anastomosis.
• Toe Dissection The dissection of soft tissue around the toe continues until the bony structures are reached. Care is taken to preserve the joint capsule and ligaments at the metatarsophalangeal joint during excision.
• Toe Transfer The toe is excised and transferred to the hand, where the blood vessels in the toe flap are anastomosed to the blood vessels in the hand.
• Nerve Anastomosis Nerves in the toe are also anastomosed to the corresponding nerves in the hand to restore sensation.
• Tendon and Ligament Repair Ligaments and tendons are anastomosed to ensure functional integration of the transferred toe.
• Stabilization Kirschner wires are utilized to hold the bony structures in place until osteosynthesis occurs, ensuring stability during the healing process.
• Donor Site Coverage Full thickness skin grafts or flaps may be employed as needed to cover the donor site on the toe, promoting healing and minimizing scarring.

3. Post-Procedure

Post-procedure care for a toe-to-hand transfer includes monitoring the surgical site for signs of infection, ensuring proper blood flow to the transferred toe, and managing pain. Patients may require physical therapy to regain function and strength in the hand following the transfer. Follow-up appointments are essential to assess healing and the integration of the transferred toe, as well as to address any complications that may arise during the recovery process.
