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.

24134 billing questions

How is this code different from partial excision of the humerus?

Use this code when the operation removes a sequestrum from the humeral shaft or distal humerus. Partial excision is a different service when the procedure is not specifically removal of a sequestrum.

What documentation supports reporting this code?

The operative report should identify the humeral shaft or distal humerus as the site and describe removal of devitalized bone or a sequestrum, along with the clinical indication.

What is included in the global period?

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?

The highest-valued procedure is paid in full, and other procedures are paid at 50% under the standard multiple procedure reduction.

Can modifier 50 or an assistant-at-surgery service be reported?

For bilateral surgery, modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeons and team surgery are not permitted.
