What 24935 covers

This operation revises an existing upper-arm amputation stump rather than removing the arm for the first time. The surgeon may reshape the residual limb’s bone or soft tissue to address a problem such as a painful prominence, impaired healing, or difficulty fitting a prosthesis. Orthopedic and other surgeons who manage limb loss may perform the procedure in an operating room, commonly in a hospital or ambulatory surgical setting.

Report the code when the operative service is a revision of an existing upper-arm amputation; document the prior amputation, the reason for revision, and the work performed on the residual limb. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. For bilateral reporting with modifier 50, payment is at 150%. Assistant-at-surgery payment requires documentation of medical necessity; 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 24900 for the upper-arm amputation itself. Use 24935 when the patient already has an upper-arm amputation and the operation revises that residual limb.
24925Arm amputation
Both relate to surgery after upper-arm amputation, but 24935 identifies revision of an existing stump. Choose 24925 only when its specific service matches the operative report.
24940Revision of upper arm
This is a related upper-arm revision code. Compare its full current descriptor with the documented procedure before choosing between it and 24935.

24935 billing questions

How does this differ from an initial upper-arm amputation?

This code is for revising an existing upper-arm amputation stump. An initial amputation, rather than correction of a prior stump, points to an amputation code such as 24900.

What documentation supports reporting this revision?

Document the prior upper-arm amputation, the clinical problem prompting surgery, and the specific revision work performed on the residual limb.

Are related postoperative visits separately reported?

Related postoperative care during the 90-day global period is included, along with the day-before preoperative visit.

How is the code handled when other procedures are performed in the same session?

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

Can modifier 50 be used for bilateral revisions?

Yes. CMS pays bilateral reporting with modifier 50 at 150%.

When is an assistant at surgery payable?

Payment for an assistant at surgery requires documentation of medical necessity. Co-surgeon and team-surgery payment is not permitted.
