Arthroscopic surgery
About 29804: Surgical temporomandibular joint arthroscopy
Report surgical TMJ arthroscopy when a surgeon uses an arthroscope to treat joint pathology, rather than performing diagnostic inspection alone.
A surgeon inserts an arthroscope into the temporomandibular joint (TMJ) to treat joint pathology under direct visualization. Oral and maxillofacial surgeons and other surgeons who treat TMJ disorders may perform the procedure in an operating room or ambulatory surgery setting. Clinical situations can include persistent joint pain or restricted movement associated with intra-articular disease. The code represents operative arthroscopy, not a diagnostic-only examination.
Report 29804 when the operative note supports a therapeutic arthroscopic service; document the treated joint, findings, and work performed. The surgical session includes a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

29804 billing questions
How does 29804 differ from 29800?
Use 29804 when the arthroscopy includes operative treatment of the TMJ. Code 29800 is for diagnostic arthroscopy, with or without synovial biopsy, when the service is diagnostic rather than surgical.
Can diagnostic inspection be reported separately with 29804?
Diagnostic inspection of the joint is part of the operative arthroscopy. Do not separately report 29800 for the diagnostic portion of the same surgical arthroscopy.
What documentation supports 29804?
The operative report should identify the TMJ treated, describe the arthroscopic findings, and state the therapeutic work performed. Document laterality when applicable.
How is bilateral TMJ arthroscopy reported?
For bilateral surgery, report modifier 50; CMS pays the bilateral procedure at 150% under the supplied fee schedule rule.
How does the multiple-procedure reduction affect 29804?
When other procedures are performed in the same session, the highest-valued procedure is paid in full and the remaining procedures are subject to the standard 50% reduction.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires 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.
