About 25105: Open wrist joint synovectomy
Reports open removal of inflamed or abnormal synovial tissue from the wrist joint, typically to treat persistent synovitis rather than obtain a biopsy.
The surgeon opens the wrist joint and removes synovial tissue, often to treat persistent proliferative synovitis associated with inflammatory arthritis or another ongoing joint condition. An orthopedic or hand surgeon typically performs the operation in a hospital or ambulatory surgery setting. This code describes treatment of the joint lining; it is distinct from sampling a small amount of tissue for diagnosis and from removing articular cartilage or a tendon sheath.
Report the service when the operative record supports open wrist-joint exposure and synovectomy. Documentation should identify the treated wrist, the indication, and the synovial tissue removed. 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
