What 24134 covers
An orthopedic surgeon performs this operation to remove a sequestrum, a piece of devitalized bone, from the shaft or distal portion of the humerus. It is typically used when chronic osteomyelitis has left nonviable bone that requires surgical removal. The procedure is generally performed in a facility setting, where the surgeon exposes the involved bone and removes the sequestrum.
Report the code when the operative record supports removal of a sequestrum from the specified humeral region; documentation should identify the site, indication, and bone removed. The code has a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. For bilateral surgery, modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeons and team surgery are not permitted.

The day-before preoperative visit and 90 days of related postoperative care are included in the 90-day global period.
How are other procedures in the same session paid?
