CPT® Code 29846

Surgical arthroscopy of the wrist, as described by CPT® Code 29846, involves a minimally invasive procedure that allows for the examination and treatment of wrist joint issues, particularly focusing on the triangular fibrocartilage complex (TFCC). The TFCC is a critical structure in the wrist that provides cushioning and stability, and it can sustain injuries, often due to trauma such as falling on an outstretched hand. This procedure is performed under sterile conditions, typically with the patient in a supine position, ensuring optimal access to the wrist joint. The use of a pneumatic tourniquet on the upper arm helps to minimize blood flow to the area, enhancing visibility during the procedure. By employing a wrist traction device, the forearm is suspended, and traction is applied to the fingers, which aids in distracting the wrist joint and improving the visualization of the internal structures. The procedure involves making small incisions, or portals, through which an arthroscope and other surgical instruments are introduced to assess and treat the TFCC and any associated joint debris. The surgical approach allows for both the repair of peripheral tears and the debridement or excision of damaged tissue, ultimately aiming to restore function and alleviate pain in the wrist joint.
