About 23935: Deep bone drainage, humerus or elbow
Reports deep operative drainage involving the humerus or elbow when the surgeon opens the bone cortex to reach and drain the affected site.
This service involves a deep incision to reach the humerus or elbow and opening the bone cortex to drain an affected site, such as a bone abscess. It is typically performed by an orthopedic surgeon in an operating room when the infection or collection requires access through the cortex rather than drainage of a superficial or soft-tissue space.
Select 23935 when the operative work includes opening the cortex of the humerus or elbow; the operative report should identify the anatomic site, the deep collection or bone involvement, and the cortical opening and drainage performed. CMS classifies the service as major surgery with a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral procedures, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
