About 23107: Open glenohumeral joint exploration
Open glenohumeral joint exploration covers surgical inspection, drainage, or foreign-body removal when the shoulder joint requires direct operative access.
This service involves opening the glenohumeral joint for direct inspection, drainage, or removal of a foreign body. An orthopedic surgeon typically performs it in an operating room, such as when shoulder joint pathology requires open access rather than inspection through an arthroscope. The operative report should identify the joint and document the work performed through the arthrotomy.
Report 23107 when the documented service is open exploration, drainage, or foreign-body removal—not a joint biopsy or synovectomy coded to a more specific procedure. The 90-day global period includes 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 may be available; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
