Oral surgery
About 41007: Intraoral floor-of-mouth abscess drainage
Reports surgical drainage through the mouth of an abscess, cyst, or hematoma located in the floor-of-mouth spaces.
This service drains a collection in the floor of the mouth through an intraoral incision. Typical targets include sublingual or submandibular space collections and submental collections approached from inside the mouth. Oral and maxillofacial surgeons, otolaryngologists, and other surgeons who manage oral or head-and-neck infections may perform it, often in a facility when the infection requires operative drainage.
Select the code based on the collection’s anatomic site and the route used; document the location, findings, incision, and drainage performed. The service has a 90-day global period that includes the day-before preoperative visit and related postoperative care during that period. 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 50% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documented medical necessity; co-surgeon and team-surgery payment are not permitted.
