What 41155 covers
This code represents an extensive composite operation for disease involving the tongue and adjacent oral cavity. The resection includes the floor of the mouth and mandible along with neck dissection. Head and neck surgeons typically perform it in a hospital operating room for advanced oral cavity cancer when the documented disease and operative plan require removal of these connected structures. The operative report should identify the structures removed and the neck dissection performed.
Report the code when the documented operation matches this combined extent, rather than a tongue-only resection or a composite procedure with different components. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When other 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. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this code’s anatomy and descriptor.

41155 billing questions
How is this distinguished from a tongue-only resection?
This code is for a composite operation that includes resection of the floor of the mouth and mandible along with neck dissection. A tongue-only procedure does not describe that operative combination.
When should 41153 be considered instead?
Compare the operative components with the specific composite procedure represented by 41153. The documented structures removed and whether a neck dissection was performed determine which code fits.
Can modifier 50 be reported?
No. Modifier 50 is inappropriate for this code’s anatomy and descriptor.
What documentation supports reporting this code?
The operative report should identify the tongue and adjacent structures resected, the mandibular resection, and the neck dissection. It should make clear that the combined operative extent matches this composite procedure.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and related postoperative care during the 90-day period are included in the global surgery payment.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
