What 41135 covers
This service combines removal of part of the tongue with a radical neck dissection on one side. It is typically performed by a head and neck surgeon or otolaryngologist in a hospital operating room for a patient whose oral tongue cancer requires both procedures. The operative record should make clear the extent of tongue resection and that a unilateral radical, rather than a more limited, neck dissection was performed.
Report the combined code when both components are performed; do not separately report the included neck dissection as though it were a standalone service. The 90-day global includes the day-before preoperative visit and related postoperative care during the following 90 days. If other procedures are performed in the same session, the highest-valued procedure is paid in full and additional procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

41135 billing questions
When should this be chosen over 41120 or 41130?
Use 41135 when partial tongue removal is performed together with a unilateral radical neck dissection. Codes 41120 and 41130 describe tongue resections without that included neck procedure.
Can the neck dissection be billed separately?
The unilateral radical neck dissection is part of this combined service. Do not separately report it as a standalone neck dissection for the same operative work.
Is modifier 50 appropriate?
No. CMS identifies bilateral adjustment as inapplicable to this code, and modifier 50 is inappropriate.
What documentation supports reporting 41135?
The operative report should describe the partial tongue resection and identify the unilateral radical neck dissection performed. It should distinguish that extent of neck surgery from a more limited dissection.
How does the global period affect postoperative visits?
The 90-day global includes the day-before preoperative visit and related postoperative care for 90 days after surgery.
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.

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.
