About 24931: Upper-arm amputation with immediate prosthesis
Reports amputation through the upper arm when the surgeon places a prosthetic implant immediately as part of the same operative procedure.
This service combines removal of the arm through the humerus with immediate placement of a prosthetic implant. It may be performed by an orthopedic or other surgeon treating an upper-extremity condition that requires amputation and allows immediate implant placement. The operative report should make clear that the implant was placed during the amputation procedure, rather than fitted later as a separate prosthetic service.
Select this code from the documented amputation level and operative technique, including immediate implant placement. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

24931 billing questions
What distinguishes this code from other upper-arm amputation codes?
The operative report must support amputation through the humerus with immediate placement of a prosthetic implant. Compare the documented technique with the applicable neighboring amputation code before selecting the code.
What documentation supports reporting this code?
Document the amputation level, operative technique, and placement of the prosthetic implant during the same procedure. A later prosthetic fitting alone does not establish that the immediate-implant service was performed.
How is bilateral surgery reported?
For bilateral procedures, report modifier 50; CMS pays the bilateral procedure at 150%.
How does the multiple-procedure rule affect payment?
When other procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
