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

What 28054 covers

A surgeon obtains a tissue sample from the synovial lining of a toe joint for diagnostic evaluation. This may be performed by a podiatric surgeon or an orthopedic foot and ankle surgeon in an operating room when a joint disorder requires tissue examination, such as suspected inflammatory or proliferative synovial disease. The specimen is submitted for examination; the service is sampling, not removal of the joint lining as treatment.

Report the code when the operative record identifies the toe joint sampled and documents that lining tissue was obtained for biopsy. It has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. For bilateral reporting, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
