Orthopedic surgery
About 25100: Open wrist joint biopsy
An open wrist arthrotomy to obtain intra-articular tissue for diagnostic evaluation when a surgeon needs a surgical specimen rather than joint fluid alone.
The surgeon opens the wrist joint and removes a tissue sample for diagnostic evaluation. The specimen may be synovium or other intra-articular tissue submitted for pathologic or microbiologic study when the cause of persistent synovitis, suspected infection, or another joint abnormality remains uncertain. Orthopedic and hand surgeons typically perform this procedure in a hospital operating room or ambulatory surgery center; it is an open surgical biopsy, not needle aspiration or arthroscopic sampling.
Report the code when the operative record supports an open joint approach and tissue was obtained for biopsy. Document the wrist, operative approach, sampled tissue, and diagnostic purpose. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one 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 payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

25100 billing questions
When is this code more appropriate than 25101?
Use 25100 when the surgeon opens the wrist joint to obtain tissue for diagnostic evaluation. Code 25101 describes wrist-joint exploration or treatment rather than a biopsy-focused service.
Can the tissue examination be billed separately?
The operative service covers access to the joint and tissue collection. A laboratory or pathologist may report the examination of the submitted specimen as a separate service when performed.
How is a biopsy of both wrists reported?
CMS lists this as a bilateral procedure; modifier 50 is paid at 150%. The operative documentation should support biopsy of both wrist joints.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon be reported?
Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted for this code under the CMS facts provided.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
