What 25909 covers

This code covers further surgery on a previously amputated forearm, rather than the initial removal of the forearm. A hand or upper-extremity surgeon may revise the residual limb when the stump needs operative correction, such as for a problematic scar, wound, or bony contour. The service is typically performed in a hospital or ambulatory surgical setting; the operative report should establish the prior amputation and the revision performed.

Report the code when the documented procedure meets its specific billing code definition, not merely because the patient has a prior amputation. CMS assigns a 90-day global period: the day-before preoperative visit and related care during the following 90 days are included. If multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral reporting with modifier 50, CMS pays 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

25900Forearm amputation
Use 25900 for the initial forearm amputation through the radius and ulna. Use 25909 for a qualifying revision of a prior forearm amputation.
25907Amputation revision
Both relate to forearm amputation revision. Choose based on the operative criteria in the code descriptors and the work documented, not the general label of stump revision.
25924Amputation revision
25924 concerns revision at the wrist level. This code concerns revision at the forearm level; the documented anatomic site guides selection.

25909 billing questions

How is this different from a primary forearm amputation?

This code is for surgery on an existing forearm amputation stump. A code for primary forearm amputation describes the initial removal, not subsequent stump revision.

How should I distinguish this from 25907?

Both codes concern forearm amputation revision. Apply the specific operative criteria in the billing code descriptors; the fact that a stump was revised by itself does not establish which code applies.

Are routine postoperative visits separately reported?

Related postoperative care during the 90-day global period is included, as is the day-before preoperative visit. The global period does not include unrelated services.

Can I report modifier 50 for bilateral revisions?

Yes. CMS treats this as a bilateral procedure and pays 150% when reported bilaterally with modifier 50.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. CMS does not permit co-surgeons or team surgery for this code.

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.
