What 25900 covers
The surgeon removes the forearm at a level that transects both the radius and ulna. This major operation may be performed for devastating trauma, an unsalvageable infection, or tissue loss from impaired blood flow. Orthopedic, hand, or other surgeons with appropriate expertise may perform it, usually in a hospital or other surgical facility. The operative report should establish the amputation level and describe the procedure performed.
Select this code when the amputation is at the forearm level through both bones; a wrist-level or hand-level amputation is a different service. Distinguish the initial amputation from later surgery on an existing stump. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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 identifies a bilateral procedure, paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

How to choose
- 25905Forearm amputation
- Both codes concern forearm amputation, but 25905 represents a different specified circumstance. Base selection on the operative details and the full descriptor for that code.
- 25915Forearm amputation
- This is another forearm-amputation code with a distinct specified circumstance. Confirm the documented procedure matches its full descriptor rather than choosing by anatomy alone.
- 25920Hand amputation
- This code is for removal at the wrist. Use 25900 when the amputation is through the forearm bones.
- 25927Hand amputation
- This code describes amputation at the hand level, not through the forearm.
25900 billing questions
How do I distinguish this from a wrist-level amputation?
Use this code when the amputation passes through the forearm bones. A wrist-level amputation is reported with a code for that more distal level.
Is this for revision of an existing forearm stump?
No. This code describes the forearm amputation itself. Use an appropriate revision code when the service is later surgery on an existing amputation stump.
What documentation supports reporting this code?
The operative report should document the level of removal and that the procedure transects both the radius and ulna. It should also describe the work performed and the clinical reason for the amputation.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and related postoperative care during the 90-day period are included in the global surgical service.
Can an assistant surgeon be reported?
Assistant-at-surgery payment is available only when medical necessity is documented. CMS does not permit co-surgeon or team-surgery payment for this code.
How is a bilateral procedure handled?
Report modifier 50 for a bilateral procedure; CMS pays the code at 150%. If other procedures are performed in the same session, the standard multiple-procedure reduction also applies.
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.
