What 24102 covers
The surgeon opens the elbow joint and removes synovial tissue, typically to address clinically significant synovitis, such as persistent proliferative inflammation. An orthopedic surgeon generally performs this operation in a hospital or other surgical facility. The code describes an arthrotomy with synovectomy, not an isolated diagnostic sample or an arthroscopic procedure.
Select 24102 when the operative report supports removal of synovium as treatment; a limited synovial sample for diagnosis points to a different service. Document the affected elbow, surgical approach, reason for synovectomy, and work performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral surgery, 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.

24102 billing questions
When should 24102 be chosen instead of 24100?
Use 24102 when the surgeon removes synovium therapeutically during an elbow arthrotomy. Code 24100 describes an elbow arthrotomy for synovial biopsy alone.
Is an arthroscopic elbow synovectomy reported with 24102?
No. 24102 describes an arthrotomy; an arthroscopic synovectomy is represented by the arthroscopy code that matches the extent of synovectomy performed.
What documentation supports 24102?
The operative report should identify the elbow, the arthrotomy approach, the synovitis being treated, and the synovial tissue removed.
How is bilateral elbow surgery handled?
CMS lists bilateral reporting with modifier 50 and payment at 150%. The documentation should support treatment of both elbows.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What postoperative care is included?
24102 has a 90-day global period that includes the day-before preoperative visit and 90 days of related postoperative care.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
