What 25355 covers
This service involves cutting and realigning the radius in its middle or proximal third to correct a bony deformity. An orthopedic or hand surgeon may perform it for a symptomatic radial malunion, such as angulation or rotation after a forearm fracture. The procedure is generally performed in an operating room, with the surgeon stabilizing the corrected bone as needed.
Choose this code for an osteotomy of the radius in the middle or proximal third; the distal-third radius osteotomy is a different code. The operative report should identify the treated bone and segment, the deformity and correction performed, and any stabilization. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

25355 billing questions
How is this different from 25350?
25355 is for an osteotomy in the middle or proximal third of the radius. Use 25350 for the distal third.
Can the radius and ulna osteotomies be reported together?
If the operative service corrects both bones, compare the documentation with 25365, which covers osteotomy of the radius and ulna. Do not use 25355 alone to represent an osteotomy of both bones.
What documentation supports selection of this code?
Document the radius as the treated bone, the middle or proximal segment, the deformity being corrected, and the osteotomy and realignment performed.
How should bilateral procedures be reported?
For bilateral procedures, report modifier 50; CMS pays the bilateral procedure at 150%.
Does the procedure have a global period?
Yes. It has a 90-day major-surgery global period that includes the day-before preoperative visit and 90 days of related postoperative care.
How does CMS handle other procedures performed in the same session?
The highest-valued procedure is paid in full, and other procedures in the same session are paid at 50%. An assistant at surgery may be paid.
