Orthopedic surgery
About 24100: Open elbow synovial biopsy
Reports open access to the elbow joint to obtain synovial tissue for biopsy when the operation does not include a broader joint procedure.
The surgeon opens the elbow joint and removes synovial tissue for diagnostic examination. Orthopedic surgeons typically perform this procedure in a hospital or other surgical facility when tissue sampling is needed to investigate an abnormal joint lining, such as suspected inflammatory or infectious disease. The service is limited to obtaining the biopsy; it is not the code for a more extensive joint exploration or synovectomy.
Report the code when the operative note supports an open elbow-joint approach and synovial biopsy as the procedure performed. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral reporting with modifier 50, CMS pays 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

24100 billing questions
When should this code be used instead of 24101?
Use this code for open elbow-joint access to obtain synovial tissue only. Code 24101 describes a broader joint exploration or removal service, with or without biopsy.
Does this code include the pathology examination?
It reports the surgeon’s procedure to obtain the tissue, not the pathologist’s examination. A separately performed pathology service may be reported by the appropriate laboratory or pathologist.
How does this differ from elbow synovectomy?
This code covers biopsy sampling of synovium. When the operation removes synovial tissue as a therapeutic synovectomy, consider 24102 instead.
What documentation supports reporting this service?
The operative report should establish an open approach to the elbow joint and removal of synovial tissue for biopsy. It should distinguish sampling from joint exploration, loose-body removal, or synovectomy.
How are bilateral procedures and multiple same-session procedures handled?
CMS pays bilateral reporting with modifier 50 at 150%. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures at 50%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
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.
