What 24925 covers
This code describes repeat amputation surgery through the humerus, the upper-arm bone. An orthopedic or other qualified surgeon may perform it when the existing amputation level requires further removal of the limb. The operative report should establish the humeral level and explain the work performed; this is distinct from an initial amputation and from a stump revision that does not involve re-amputation.
Report the code for the documented re-amputation, not simply because the patient has a history of upper-arm amputation. The 90-day global period includes the day-before preoperative visit and related postoperative care during the following 90 days. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 identifies a bilateral procedure, paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

24925 billing questions
How is this different from an initial upper-arm amputation?
Use 24925 for repeat amputation through the humerus, rather than the code for an initial amputation. The operative report should support that additional amputation work was performed.
How does this differ from an amputation revision code?
This code describes re-amputation through the humerus. A revision code is considered when the surgeon revises the existing amputation rather than performing re-amputation.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures in that session are subject to the standard multiple-procedure reduction.
Can modifier 50 or an assistant-at-surgery claim be used?
Modifier 50 identifies a bilateral procedure, which is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
What documentation supports reporting 24925?
Document the prior amputation, the humeral level, and the repeat amputation work performed. The operative note should distinguish re-amputation from an initial amputation or a stump revision.
