What 24931 covers

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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

24900Upper arm amputation
Use 24931 when the amputation includes immediate prosthetic implant placement. For another upper-arm amputation technique, compare the operative report with the specific listed code.
24920Upper-arm amputation
Both concern upper-arm amputation, but 24931 specifically includes immediate prosthetic implant placement. Choose based on the documented procedure, not simply the diagnosis.
24935Amputation revision
This code is for revision of an existing amputation, rather than the primary upper-arm amputation with immediate implant represented by 24931.
24940Revision of upper arm
This is a revision procedure for an upper-arm amputation. Use 24931 for the primary amputation with immediate prosthetic implant placement when the operative details support it.

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 indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
