What 41000 covers
This procedure drains a localized collection in the floor of the mouth through an intraoral approach. The collection may be an abscess, cyst, or hematoma. Oral and maxillofacial surgeons, dentists, and other qualified physicians may perform it in an office, outpatient department, or operating room, depending on the patient’s condition and the extent of the infection or collection. The documented site and route distinguish this service from drainage involving the tongue, vestibule, or extraoral neck spaces.
Report the service when the clinician actually drains a collection at the floor of the mouth; documentation should identify the site, the nature of the collection when known, and the intraoral approach. Related postoperative visits during the 10-day global period are included. 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 multiple-procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

41000 billing questions
How is this distinguished from drainage of a tongue abscess?
Use 41000 for a collection in the floor of the mouth. A collection centered in the tongue is reported with 41005.
Does the intraoral approach matter?
Yes. This code describes drainage from the floor of the mouth through an intraoral approach; document both the site and route.
Can modifier 50 be used for collections on both sides?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.
Are postoperative visits separately reported during the global period?
Related postoperative visits during the 10-day global period are included in the procedure.
Can an assistant or co-surgeon be billed?
Medicare does not pay an assistant at surgery for this service. Co-surgeon and team-surgery billing are not permitted.
What happens if other procedures are 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.
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.
