What 29843 covers

An orthopedic or hand surgeon uses a small camera and instruments through wrist portals to remove a portion of abnormal synovial tissue. This approach may be used for persistent inflammatory or proliferative synovitis affecting the wrist joint, including synovitis associated with inflammatory arthritis. The service is generally performed in an operating room or ambulatory surgery center, with the operative note identifying the involved joint and the synovium removed.

Report this code for a partial arthroscopic synovectomy, not a complete synovectomy or diagnostic inspection alone. Documentation should support the synovitis, the arthroscopic technique, and the partial extent of tissue removal. The service has a 90-day global period, including the day-before preoperative visit and related postoperative care. When related endoscopies are performed together, endoscopy-family pricing applies. For bilateral procedures, modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

29843 billing questions

How is this code different from a complete wrist synovectomy?

This code is for arthroscopic removal of part of the synovium. Use 29844 when the operative service is a complete synovectomy.

Can diagnostic wrist arthroscopy be reported separately?

Diagnostic inspection is part of the operative arthroscopy when the surgeon proceeds with a synovectomy. Code 29840 describes diagnostic wrist arthroscopy when no operative arthroscopic service is performed.

What documentation supports partial synovectomy?

The operative report should identify wrist synovitis, describe the arthroscopic removal of synovial tissue, and make clear that the removal was partial rather than complete.

How is a bilateral procedure reported?

Report modifier 50 for the bilateral procedure; CMS pays it at 150%.

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 or co-surgeon be paid?

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 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.
