What 25805 covers
An orthopedic or hand surgeon fuses the wrist bones to relieve pain and stabilize a severely damaged wrist, such as one affected by advanced arthritis, posttraumatic joint destruction, or chronic instability. In this approach, the surgeon uses a sliding bone graft as part of the fusion; the operative report should establish the fusion performed and the graft technique. The service is generally performed in a surgical facility rather than an office setting.
Report this code when the operative work is a complete wrist fusion using a sliding graft, rather than a limited fusion or a different graft approach. Documentation should identify the wrist, extent of fusion, indication, and use of the sliding graft. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 for bilateral performance is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

25805 billing questions
How is this code different from 25800?
Both describe complete wrist arthrodesis, but 25805 includes use of a sliding graft. Use 25800 when the complete fusion is performed without a bone graft.
When should 25810 be considered instead?
Use 25810 when the wrist fusion uses iliac or another autograft rather than the sliding-graft technique described by 25805. The operative report should support the graft method.
Does this code include the 90-day postoperative period?
Yes. Medicare's 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days.
How is bilateral wrist fusion handled?
For bilateral performance, report modifier 50; Medicare pays the bilateral procedure at 150%.
What should the operative note document?
Document the indication, wrist treated, complete extent of the fusion, and use of a sliding bone graft. These details distinguish 25805 from limited fusion and other graft approaches.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
