What 25800 covers
An orthopedic hand or wrist surgeon removes joint cartilage and prepares the surfaces for fusion across the wrist, then stabilizes the bones with fixation. This operation is used for conditions such as advanced post-traumatic or degenerative arthritis, painful instability, or deformity when motion-preserving treatment is unsuitable. It is generally performed in an operating room, most often in a facility setting.
Report this code when the operative work fuses the wrist as a whole and no bone graft is used. The operative report should support the extent of fusion, the indication, and whether graft material was placed; a fusion limited to selected wrist joints belongs to a different code. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 bilateral reporting is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

Can bone graft be reported with this code?
No. This code describes the wrist fusion without graft; choose the applicable graft-specific wrist arthrodesis code when graft is used.
What operative documentation supports reporting this code?
Document the diagnosis, the extent of the fusion, the joints prepared and stabilized, and that no graft was used.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
How is bilateral reporting handled?
For bilateral wrist procedures reported with modifier 50, CMS pays this procedure at 150%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
