About 61790: Stereotactic trigeminal nerve lesioning
Reports stereotactic lesioning of the intracranial trigeminal nerve, typically to treat trigeminal neuralgia when this targeted procedure is performed.
This service uses stereotactic localization to create a lesion in the intracranial trigeminal nerve, interrupting pain signals. It is most often performed for severe trigeminal neuralgia that has not responded adequately to other treatment. A neurosurgeon typically performs the procedure in a hospital setting; the specific lesioning method should be supported by the operative record. The key distinction is that the target is the trigeminal nerve itself, rather than the trigeminal tract or a separate cranial lesion.
Report the code when the documented procedure matches that target and stereotactic approach. The operative note should identify the indication, target, method, and side treated. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services are not paid, and co-surgeons and team surgery are not permitted.

61790 billing questions
How does this differ from 61791?
This code targets the intracranial trigeminal nerve. Code 61791 is for a procedure directed at the trigeminal tract, so the documented treatment target distinguishes them.
Can this be reported for trigeminal neuralgia treated at a peripheral branch?
No. This code describes stereotactic treatment of the intracranial nerve; a procedure directed at peripheral trigeminal branches may fit a different code, such as 64600 or 64605.
What documentation supports reporting this code?
The operative record should establish the trigeminal neuralgia indication, stereotactic method, intracranial nerve target, lesioning performed, and side treated.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
What happens when another procedure is performed in the same session?
Medicare pays the highest-valued procedure in full and applies the standard multiple-procedure reduction to the others. Bilateral reporting with modifier 50 is paid at 150%.
Can an assistant or co-surgeon be billed for this service?
Assistant-at-surgery services are not paid for this code. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
