What 41015 covers

This service drains a collection in the floor of the mouth through an incision made outside the mouth. Oral and maxillofacial surgeons and other surgeons treating deep oral infections may perform it, commonly in a facility when the collection requires external access. The operative report should identify the floor-of-mouth site and document the external approach and drainage performed; the code is distinguished from procedures that reach a collection through the oral cavity or target another space.

Report the service for the documented site and approach, not simply because a patient has an oral abscess. 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 procedure is paid in full and the others are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this anatomy. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
