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.

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.

41006 billing questions

How does this differ from 41005?

Both address drainage in the floor of the mouth. Use 41006 for an external approach and 41005 when the collection is drained through the oral cavity.

When is 41006 preferred over 41016?

41006 is for a floor-of-mouth collection reached externally. 41016 describes external drainage of a sublingual, submandibular, or submental space collection; choose by the documented anatomic space.

Can modifier 50 be reported?

No. Modifier 50 is inappropriate for this code’s descriptor and anatomy.

What postoperative care is included?

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

When may an assistant-at-surgery be paid?

CMS payment for an assistant at surgery requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.

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.
