What 41116 covers
This service removes a lesion arising in the soft tissue beneath the tongue, such as a localized mucosal growth or abnormal area on the floor of the mouth. Oral and maxillofacial surgeons, otolaryngologists, and other clinicians who perform oral surgery may provide it in an office or operating-room setting. The procedure is distinct from sampling a lesion for diagnosis and from removing a lesion whose site is the tongue.
Report the code when the operative documentation identifies the floor of the mouth as the lesion site and supports excision rather than biopsy alone. The service has a 90-day global period, which includes the day-before preoperative visit and related postoperative care for 90 days. 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 for this service; co-surgeons and team surgery are not permitted.

41116 billing questions
When should this be reported instead of 41108?
Use 41116 for surgical excision of a floor-of-mouth lesion. Use 41108 when the service is a biopsy of that site rather than excision.
Does a lesion on the underside of the tongue qualify?
The operative note should establish that the lesion arises in the floor of the mouth, not the tongue. Tongue lesions are reported with the applicable tongue procedure code.
Is modifier 50 appropriate for lesions on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not append modifier 50.
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.
Can an assistant surgeon or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction.
