CPT® Code 26516

Capsulodesis is a surgical procedure aimed at correcting deformities in the metacarpophalangeal (MCP) joint of the finger, specifically addressing issues related to flexion or extension. This procedure is particularly relevant for patients who experience functional limitations due to these deformities. The MCP joint is a critical joint in the hand that allows for the movement of the fingers, and any deformity can significantly impact hand function. During the capsulodesis, a surgical incision is made over the affected MCP joint to access the underlying structures. The procedure involves the exposure of the flexor pollicis longus tendon and the excision of a portion of its tendon sheath, which is essential for the subsequent steps. The volar plate, a fibrous structure that stabilizes the MCP joint, is also manipulated during the procedure. By incising the volar plate at its proximal and lateral attachments, the intrinsic muscles are divided, allowing for better positioning of the finger. The finger is then placed in a slightly flexed position to optimize its functional capabilities. The volar plate is secured against the metacarpal neck using a Kirschner wire, which helps maintain the desired position of the finger post-surgery. This procedure is coded as CPT® Code 26516 for capsulodesis of a single digit, with additional codes available for multiple digits.
