What 41007 covers

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.

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.

41007 billing questions

How is 41007 distinguished from 41008?

Both describe drainage involving floor-of-mouth spaces, but 41007 is for an intraoral approach and 41008 for an extraoral approach. Document the route used.

When is 41005 a better fit?

41005 is for drainage of a collection in the vestibule of the mouth. Use 41007 when the collection is in the floor-of-mouth spaces.

Can modifier 50 be reported?

No. CMS identifies bilateral adjustment as inappropriate for this code.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

What documentation supports an assistant-at-surgery claim?

The record must document the medical necessity of the assistant. CMS does not permit co-surgeon or team-surgery payment for this service.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full; other procedures performed in the same session are subject to the standard multiple-procedure reduction.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
