What 23155 covers
An orthopedic surgeon exposes the humerus, removes or curettes a bone cyst or benign tumor, and uses the patient’s own bone graft to fill the defect. The service is generally performed in an operating room, including a hospital outpatient department or ambulatory surgery center. The autograft is the distinguishing feature; a similar humeral lesion procedure without graft or with donor bone is coded differently.
Select this code when the operative report supports the humeral site, lesion removal or curettage, and use of autograft. The code has 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 other procedures are subject to the standard 50% reduction. Modifier 50 applies to bilateral procedures, paid at 150%. An assistant at surgery may be paid; co-surgeons are paid only with supporting documentation. Team surgery is not permitted.

Document the humeral location, the bone cyst or benign tumor treated, the removal or curettage performed, and use of autograft to fill the defect.
