CPT® Code 26535

Arthroplasty of the interphalangeal joint, as described by CPT® Code 26535, refers to a surgical procedure aimed at addressing issues within the interphalangeal (IP) joints of the fingers or toes. This procedure involves making an incision over either the dorsal (top) or volar (bottom) aspect of the joint to access the affected area. The surgeon carefully dissects the surrounding soft tissues and exposes the tendons while taking precautions to protect the nearby blood vessels and nerves. Unlike other arthroplasty procedures that may involve the placement of a prosthetic joint implant, the procedure associated with CPT® Code 26535 focuses on the repair and reconstruction of the joint without such an implant. During the surgery, the joint capsule is incised to allow access to the diseased joint tissue, which is then excised along with any bone spurs that may be present. The articular cartilage, which is the smooth tissue covering the ends of the bones in the joint, is smoothed to promote better movement and reduce pain. After the joint has been adequately prepared, it is flushed with sterile saline to remove any debris. The final steps involve closing the joint capsule, followed by the overlying soft tissues and skin. This procedure is specifically coded under 26535 for each interphalangeal joint treated with arthroplasty alone, distinguishing it from other codes that involve the use of prosthetic implants.
