About 23105: Open shoulder arthrotomy with synovectomy
Open glenohumeral arthrotomy with synovectomy is reported when a surgeon removes diseased synovial tissue from the shoulder joint through an open approach.
The surgeon opens the glenohumeral joint and removes diseased synovial tissue. Orthopedic surgeons typically perform this operation in a hospital operating room for shoulder conditions requiring synovectomy by an open approach. The operative report should identify the joint, describe the synovial tissue removed, and support that the procedure was performed through an open approach rather than arthroscopically.
Report this code when synovectomy is performed, not for an open joint entry done only to obtain a biopsy or explore the joint. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard reduction. Modifier 50 identifies bilateral surgery, paid at 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

23105 billing questions
How does this differ from 23100?
