Nerve surgery
About 64795: Peripheral nerve biopsy
Report a nerve biopsy when a surgeon removes peripheral nerve tissue for diagnostic evaluation, such as investigating suspected vasculitic neuropathy.
A surgeon obtains a sample of peripheral nerve tissue so it can be examined to help diagnose a neuropathy. A sural nerve biopsy is a familiar example in the evaluation of suspected vasculitic neuropathy. The service is generally performed by a surgeon, such as a neurosurgeon or peripheral nerve surgeon, in an operating or procedure setting when tissue sampling is clinically indicated.
Select this code for diagnostic nerve tissue sampling, not removal of a nerve lesion as the treatment itself. The operative report should identify the nerve sampled, the diagnostic reason, and the biopsy performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one 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 service. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

64795 billing questions
When should I report a nerve biopsy instead of a nerve-lesion excision code?
Report 64795 when nerve tissue is sampled to establish a diagnosis. If the procedure removes a nerve lesion as treatment, use the code that describes that lesion and its location or type.
Is same-day preoperative or postoperative care included?
Yes. The 0-day global period includes same-day preoperative and postoperative care.
Can modifier 50 be used for biopsies on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code. Do not append modifier 50.
How does Medicare handle this service 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.
Can an assistant or co-surgeon be paid for the biopsy?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
What documentation supports reporting 64795?
Document the nerve sampled, the diagnostic indication, and the tissue-sampling procedure. The record should make clear that the purpose was diagnostic biopsy rather than therapeutic removal of a nerve lesion.
