About 25445: Trapezium prosthetic replacement arthroplasty
Reports operative arthroplasty replacing the trapezium with a prosthesis, commonly selected for reconstruction of painful thumb-base joint disease.
This service is an operative arthroplasty in which a prosthetic implant replaces the trapezium, the carpal bone at the base of the thumb. It is most often encountered in reconstruction for painful thumb carpometacarpal disease when the surgeon selects a trapezial prosthesis. An orthopedic hand surgeon typically performs the procedure in an operating room, such as in a hospital outpatient department or ambulatory surgery center.
Report the code when the operative record supports prosthetic replacement of the trapezium, rather than trapeziectomy with interposition or suspensionplasty. Documentation should identify the treated side, the operative indication, and the prosthetic replacement performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care through day 90. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 for bilateral surgery is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
