CPT® Code 26561

Syndactyly is a congenital condition characterized by the fusion of two or more fingers, resulting in a web-like appearance. This condition can vary in complexity; simple syndactyly involves only the soft tissues of the fingers, while complex syndactyly may include involvement of bone, cartilage, or nails. The procedure described by CPT® Code 26561 specifically addresses the repair of syndactyly in each web space using skin flaps and grafts. In this surgical intervention, the surgeon performs a meticulous dissection of the soft tissues to separate the conjoined fingers, ensuring that the blood supply to each digit is preserved. Unlike simpler procedures that may only require the division of soft tissues, this technique incorporates full-thickness skin grafts harvested from donor sites, typically the plantar instep, to facilitate complete closure of the zigzag incisions created during the surgery. This approach is essential for achieving optimal aesthetic and functional outcomes for the patient, particularly in cases where the syndactyly is more complex and requires additional tissue for effective closure.
