CPT® Code 26520

Capsulectomy or capsulotomy is a surgical procedure aimed at addressing contractures in the metacarpophalangeal (MCP) or interphalangeal (IP) joints, which can occur due to various conditions such as disease, burns, or other injuries. The primary goal of this procedure is to relieve either extension or flexion contractures that restrict the normal range of motion in these joints. In the context of CPT® Code 26520, the focus is specifically on the treatment of contractures affecting the MCP joint. The procedure involves making incisions in strategic locations depending on the type of contracture present. For extension contractures, an incision is made on the dorsal side of the joint, while for flexion contractures, the incision is made on the volar side. The surgical steps include incising the retinaculum, freeing it from the collateral ligament, and incising or excising portions of the joint capsule to alleviate the contracture. This meticulous approach not only aims to restore function but also to enhance the overall range of motion in the affected joint.
