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

What 28022 covers

This code covers open access to a metatarsophalangeal (MTP) joint for exploration, drainage, or removal of a loose or foreign body. It may be used for an MTP joint at the base of a toe when operative evaluation or one of these treatments is performed. Orthopedic foot and ankle surgeons and podiatric surgeons typically perform the procedure in an operating room or another surgical setting.

Report the code for the MTP joint work documented in the operative note; include the specific joint, the reason for opening it, and the findings and actions taken. Exploration, drainage, and removal of a loose or foreign body are part of this service, rather than separate services for the same joint work. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.
