What 33120 covers

A cardiac surgeon removes a tumor located inside a heart chamber during an operation using cardiopulmonary bypass. An atrial myxoma is a typical example. The operation is generally performed in a hospital operating room; the operative report should establish the tumor’s intracardiac location, its removal, and use of bypass. This code distinguishes removal of an intracardiac tumor from excision of a tumor on the heart’s external surface.

Report the code when the documented procedure matches that service, not merely because a cardiac mass was evaluated or treated. Cardiopulmonary bypass is part of the coded service. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this procedure. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team-surgery billing is not permitted.
