What 26841 covers

This procedure fuses the joint at the base of the thumb, where the first metacarpal meets the wrist-side carpal bone. The surgeon prepares the joint surfaces and may use internal fixation to hold the bones in position while they heal together. Hand surgeons commonly perform it in an operating room for selected patients with painful thumb-base arthritis, instability, or joint damage after trauma.

Report 26841 for the thumb carpometacarpal fusion when the service does not include the autogenous bone graft described by the graft-specific code. The operative report should identify the joint fused, the indication, the preparation and fixation performed, and whether a graft was used. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 identifies bilateral performance, paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeon payment requires supporting documentation. Team surgery is not permitted.
