CPT® Code 26587

Polydactyly of the hand is a congenital condition characterized by the presence of one or more extra digits. This condition can manifest in various forms, classified primarily into three types based on the anatomical structures involved. Type I polydactyly involves only soft tissue, Type II includes bone and/or cartilage, and Type III features a complete duplication of the digit along with the metacarpal bone. Additionally, polydactyly can be categorized based on the location of the extra digit: radial or pre-axial polydactyly refers to an extra thumb, ulnar or post-axial polydactyly indicates an extra small finger, and central polydactyly involves an additional digit located in the central part of the hand. The procedure denoted by CPT® Code 26587 specifically addresses the reconstruction of a polydactylous digit that includes both soft tissue and bone. This surgical intervention is necessary to create a functional single digit from the duplicated or split digit, particularly in cases of pre-axial or post-axial polydactyly. The reconstruction process entails the excision of excess bone or cartilage, followed by the meticulous rearrangement of skin, soft tissue, tendons, joints, and ligaments to achieve a cohesive and functional digit. In cases of central polydactyly, the reconstruction is often more intricate, requiring comprehensive surgical techniques to address both the hand and the fingers effectively.
