About 41017: Intraoral floor-of-mouth lesion drainage
Reports intraoral incision and drainage of an abscess, cyst, or hematoma located in the floor of the mouth beneath the tongue.
This procedure drains an abscess, cyst, or hematoma in the floor of the mouth through an incision made from inside the oral cavity. The target is the tissue beneath the tongue, rather than a lesion in the tongue itself or the cheek-side vestibule. Oral and maxillofacial surgeons and otolaryngologists may perform it, commonly in a surgical setting; the operative note should identify the floor-of-mouth location and describe the intraoral approach and drainage performed.
Select this code based on both the lesion’s anatomic site and the route used. The record should support that the treated lesion was in the floor of the mouth and accessed intraorally. Medicare treats the service as major surgery with a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate for this code. An assistant at surgery is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

41017 billing questions
How is this code distinguished from 41018?
Both concern drainage in the floor-of-mouth region, but 41017 is for an intraoral approach and 41018 is for an extraoral approach. Document the route used to reach the lesion.
When would 41016 be a closer code?
41016 concerns drainage of a lesion of the tongue by an extraoral approach. Use 41017 for a floor-of-mouth lesion reached from inside the mouth.
Can modifier 50 be reported?
No. The anatomy and descriptor make modifier 50 inappropriate for this service.
What documentation supports reporting 41017?
Document the lesion’s floor-of-mouth location, the intraoral route, and the drainage performed. A general reference to a mouth abscess without site and approach detail may not establish the code selection.
How does Medicare handle other procedures performed in the same session?
The highest-valued procedure is paid in full, and other procedures subject to the standard multiple procedure reduction are paid at 50%.
Can an assistant surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.
