What 29846 covers

An orthopedic or hand surgeon uses a small camera and instruments through wrist portals to address a triangular fibrocartilage complex (TFCC) tear or remove damaged or inflamed tissue within the joint. Typical cases include a symptomatic TFCC injury on the ulnar side of the wrist or other intra-articular pathology requiring arthroscopic debridement. The operation is generally performed in a surgical setting, with the operative report identifying the pathology and the work performed under visualization.

Report this code when the arthroscopic service includes TFCC excision or repair, or joint debridement, rather than diagnostic inspection alone or a different defined wrist procedure. Documentation should describe the treated structure, the tear or tissue abnormality, and whether tissue was removed, repaired, or debrided. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When related endoscopies are performed together, endoscopy-family pricing applies. For bilateral procedures, modifier 50 is paid at 150%. An assistant is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

29846 billing questions

When is this code appropriate instead of a diagnostic wrist arthroscopy?

Use this code when the surgeon performs arthroscopic TFCC excision or repair, or joint debridement. Diagnostic inspection without that therapeutic work is a different service.

Does this code cover wrist synovectomy?

The wrist arthroscopy family has separate codes for partial and complete synovectomy. Select the code that matches the synovectomy performed rather than treating synovectomy alone as TFCC treatment or joint debridement.

What should the operative report document?

Identify the TFCC or other joint tissue treated, the pathology found, and the arthroscopic work performed, such as repair, excision, or debridement.

How is a bilateral service reported under CMS rules?

For bilateral procedures, modifier 50 is paid at 150%. The operative record should support treatment of both wrists.

Can an assistant surgeon be paid for this procedure?

CMS pays an assistant at surgery only when documentation supports medical necessity. Co-surgeons and team surgery are not permitted.

What postoperative care is included?

This is major surgery with a 90-day global period. The day-before preoperative visit and related postoperative care during the 90 days are included.
