About 26641: Closed reduction of thumb carpometacarpal dislocation
Reports closed manipulation of a dislocated thumb carpometacarpal joint when reduction is performed under anesthesia and no fracture-dislocation is treated.
This service treats a dislocation at the base of the thumb, where the first metacarpal meets the wrist bones. The physician, commonly an orthopedic or hand surgeon, manipulates the joint back into position under anesthesia without open surgical exposure. It may be performed in an operating room or another setting equipped to provide the required anesthesia and manage the reduction.
Report the code for an isolated thumb carpometacarpal dislocation treated by closed manipulation under anesthesia, not for a fracture-dislocation or an open procedure. Documentation should identify the joint and side, establish the dislocation, and describe the reduction and anesthesia. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
