CPT® Code 26135

The CPT® Code 26135 refers to a surgical procedure known as synovectomy of the metacarpophalangeal (MCP) joint, which includes the intrinsic release and extensor hood reconstruction for each digit. The MCP joints are critical articulations located between the metacarpal bones of the hand and the proximal phalanges of the fingers, allowing for a wide range of motion essential for hand function. In this procedure, the surgeon makes an incision over the affected MCP joint to access the joint capsule. The synovial tissue, which is often inflamed and can cause pain and dysfunction, is excised to alleviate symptoms. Additionally, the extensor hood, which is a complex structure formed by the extensor tendons that facilitate finger extension, is carefully dissected and reconstructed. This reconstruction is vital for ensuring that the interconnected tendons and ligaments can function properly, allowing for smooth and balanced motion of the fingers. The procedure is particularly beneficial for patients suffering from conditions that affect the MCP joint, such as rheumatoid arthritis or other inflammatory joint diseases, where the synovial tissue becomes problematic.
