What 27625 covers
An orthopedic surgeon removes abnormal synovial tissue from the ankle joint through an open approach. The procedure may be performed for persistent synovitis, including synovial inflammation associated with inflammatory arthritis, when removing the affected lining is the planned treatment. It is typically performed in an operating room, with the operative report identifying the joint and describing the tissue removed and the extent of the synovectomy.
Choose this code for a standard-extent ankle synovectomy; use the extensive sibling code when the documented resection meets that greater extent. The operative report should support the indication, open approach, ankle site, and scope of tissue removal. CMS 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27625 billing questions
How do I distinguish this code from 27626?
Both describe open ankle synovectomy. Use 27625 for standard extent and 27626 when the operative documentation supports an extensive synovectomy.
Can this code be used for arthroscopic synovectomy?
No. This code describes an open ankle synovectomy. For arthroscopic partial synovectomy, consider 29895 when the documented service fits that code.
What should the operative report document?
Document the ankle joint treated, the reason for removing synovium, the open approach, and the extent of tissue removed. Those details support code selection against the extensive sibling.
How is bilateral ankle synovectomy reported?
CMS identifies this as a bilateral procedure; modifier 50 is paid at 150%. The operative documentation should support treatment of both ankles.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
May an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, while team surgery is not permitted for this code.
