What 41006 covers

This service is drainage of a collection in the floor of the mouth through an incision made externally, such as through the skin beneath the jaw. The surgeon opens the collection and evacuates its contents. Oral and maxillofacial surgeons and otolaryngologists may perform it in an operating room or, when clinically appropriate, another surgical setting. The external route distinguishes this service from drainage approached through the oral cavity.

Select the code based on the documented site and operative route; the record should identify the floor-of-mouth collection and the external approach. This major surgery code includes 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 other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documented medical necessity; co-surgeon and team-surgery billing are not permitted.
