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.

41015 billing questions

When is this code chosen over an intraoral drainage code?

Use it when the operative documentation identifies a floor-of-mouth collection and the surgeon drains it through an external incision. Drainage reached through the mouth is coded to the applicable intraoral service.

How is this distinguished from 41007?

The distinction is the documented target and approach: 41015 describes external access to a floor-of-mouth collection, while 41007 is for drainage of a submandibular-space collection.

What should the operative report document?

Document the collection's anatomic site, the external route of access, and the drainage performed. A general diagnosis of mouth abscess without the site and approach is not enough to establish this specific service.

Can modifier 50 be used for bilateral drainage?

No. CMS identifies bilateral adjustment as inappropriate for this code's descriptor and anatomy.

How does the multiple-procedure rule affect payment?

For procedures performed in the same session, the highest-valued procedure is paid in full and the other procedures are subject to the standard multiple-procedure reduction. Assistant-at-surgery payment requires medical-necessity documentation.

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.
