Peripheral nerve surgery
About 64790: Major peripheral nerve sheath tumor excision
Reports surgical removal of a neurofibroma or schwannoma involving a major peripheral nerve other than the sciatic nerve.
This code describes operative removal of a neurofibroma or schwannoma arising from a major peripheral nerve, excluding the sciatic nerve. A peripheral nerve, neurosurgical, or orthopedic surgeon typically exposes the involved nerve and removes the tumor, taking care to distinguish the mass from functioning nerve fascicles. The service may occur in a hospital or other surgical setting; the code is not for a superficial cutaneous nerve lesion or an ordinary traumatic neuroma.
Select the code based on the operative findings, the involved nerve, and the extent of tumor removal. Documentation should identify the nerve and lesion, describe the excision, and support that the lesion is a nerve sheath tumor rather than a neuroma. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery and co-surgeon payment require supporting documentation; team surgery is not permitted.

64790 billing questions
How is this different from code 64784?
This code is for a neurofibroma or schwannoma involving a major peripheral nerve other than the sciatic nerve. Code 64784 describes removal of a neuroma from a major peripheral nerve.
When would code 64792 be more appropriate?
Use 64792 when the neurofibroma or schwannoma removal is extensive, including peripheral nerve involvement. The operative report should support the extent that distinguishes it from this code.
Can modifier 50 be used for bilateral lesions?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care. Those services are not separately reported as routine care within the global period.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
What happens when another procedure is performed in the same session?
The highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction, with payment at 50%.
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.
