About 24920: Upper-arm amputation with primary closure
Reports surgical removal of the upper arm through the humerus with primary closure, typically for a non-salvageable limb or upper-arm malignancy.
The surgeon removes the upper arm through the humerus and closes the residual limb during the same operation. This approach may be used when trauma, extensive infection, severe loss of blood supply, or malignancy makes the limb unsalvageable. The operation is generally performed in a hospital operating room by an orthopedic or other qualified surgeon; the closure distinguishes it from a guillotine amputation left open.
Select this code when the operative report supports upper-arm amputation with primary closure, rather than an open guillotine procedure or a later closure or revision. Documentation should identify the amputation level and describe the removal and closure performed. Medicare assigns 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 other procedures are subject to the standard 50% reduction. Modifier 50 bilateral reporting is paid at 150%. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

24920 billing questions
How does this differ from 24900?
24920 is for an upper-arm amputation with primary closure. 24900 describes a circular, or guillotine, amputation, which is left open rather than closed at the initial operation.
Can a later stump closure be reported with this code?
This code represents primary closure during the amputation operation. A later closure or scar procedure is a separate service and should be evaluated under the code that describes that later work.
What documentation supports 24920?
The operative report should establish the upper-arm level through the humerus and describe primary closure of the residual limb during the procedure.
How is bilateral amputation reported?
For bilateral procedures, report modifier 50; CMS pays the bilateral procedure at 150%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
