What 25810 covers

An orthopedic hand or upper-extremity surgeon uses this code for complete wrist fusion supported by the patient’s own bone graft, commonly obtained from the iliac crest or another donor site. The operation joins the wrist across the intended fusion surfaces, often for severe painful arthritis, post-traumatic joint damage, or an unstable wrist when preserving wrist motion is not the goal. It is generally performed in an operating room with fixation selected by the surgeon.

Report this code when the operative report supports complete wrist arthrodesis with autograft; obtaining the graft is included. The 90-day global period includes 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

25810 billing questions

How does this differ from 25800?

Both describe complete wrist fusion, but 25810 includes autograft use, while 25800 is the complete fusion code without bone graft.

Can the graft harvest be billed separately?

No. Obtaining the autograft is included in 25810.

When is 25805 a better choice?

Use 25805 when the complete wrist fusion is performed with a sliding graft technique rather than the iliac or other autograft service represented by 25810.

What documentation supports 25810?

The operative report should establish complete wrist arthrodesis and use of the patient’s own bone graft. It should also identify the graft source and the procedure performed.

How is bilateral wrist fusion paid?

CMS pays bilateral reporting with modifier 50 at 150%. The code also has a 90-day global period for related postoperative care.
