Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 29820 covers

During shoulder arthroscopy, the surgeon removes a portion of abnormal synovial lining to treat active synovitis. The lining may be thickened and inflamed in conditions such as inflammatory arthritis or degenerative shoulder disease. An orthopedic surgeon performs the procedure with an arthroscope and instruments through small portals, commonly in a hospital outpatient department or ambulatory surgery center. This is therapeutic tissue removal, not simply inspection or biopsy.

Report 29820 when the operative note supports partial synovectomy and identifies the synovium treated and work performed; synovitis noted during inspection alone is not enough. Distinguish partial removal from complete synovectomy. Diagnostic inspection that is part of the same surgical arthroscopy is not separately reported. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. Endoscopy-family pricing applies when related endoscopies are performed together. For bilateral surgery, modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
