What 64792 covers
This service involves surgically exposing and removing a neuroma arising from a cranial nerve. It is typically performed by a neurosurgeon or an otolaryngologist or head-and-neck surgeon when a focal nerve lesion is the operative target. The code is distinguished by the cranial nerve location; a neuroma involving a peripheral nerve of an extremity or a sympathetic nerve belongs to a different anatomic category. Cases are generally performed in a hospital operating room rather than an office setting.
Report the service when the operative record supports removal of a cranial nerve neuroma, identifying the nerve, lesion, and work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during the following 90 days. 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 50% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose
- 64790Nerve tumor removal
- Use this code for a neuroma arising from a cranial nerve; 64790 identifies a neuroma of a sympathetic nerve.
- 64784Neuroma excision
- Use 64784 for a major peripheral nerve outside the arm or leg. A cranial nerve neuroma belongs to this code instead.
- 64795Nerve biopsy
- 64795 is for obtaining a nerve biopsy specimen. This code describes operative removal of a cranial nerve neuroma, not diagnostic sampling alone.
- 64771Cranial nerve transection
- 64771 describes interruption of a cranial nerve. This code is for removal of a neuroma, not nerve transection as the operative goal.
64792 billing questions
How is this code distinguished from other neuroma excision codes?
The defining feature is that the neuroma arises from a cranial nerve. Codes for neuromas of skin, digits, extremity nerves, sciatic nerve, or sympathetic nerve describe different anatomic categories.
What should the operative note identify?
Document the cranial nerve involved, the neuroma and its location, and the surgical work performed to remove it. The record should make clear that the target was a neuroma rather than a nerve biopsy or nerve interruption.
Can modifier 50 be used for bilateral neuromas?
No. CMS identifies bilateral adjustment as inappropriate for this descriptor and anatomy, so modifier 50 should not be appended.
How are other procedures in the same session paid?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50% when performed in the same session.
What postoperative care is included in the global period?
The 90-day global includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
