Nerve surgery
About 64864: Extracranial cranial nerve repair
Reports surgical suture repair of an extracranial facial nerve injury, such as a transection requiring operative reconnection of the nerve ends.
This service involves surgically reconnecting an injured extracranial cranial nerve, most often the facial nerve, by bringing the nerve ends together and repairing them. It may be performed by an otolaryngologist, plastic surgeon, or neurosurgeon in an operating room after facial trauma or an operative injury, including damage encountered during parotid-region surgery. The repair is distinct from reconstruction that bridges a nerve gap with a graft or redirects another nerve to restore facial function.
Report the code when the operative record supports repair of an extracranial cranial nerve and identifies the nerve and repair performed. The day-before preoperative visit and 90 days of related postoperative care are included in the major-surgery global period. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is not appropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

64864 billing questions
How is this different from 64865?
64864 is for repair of an extracranial cranial nerve. Code 64865 describes intracranial cranial nerve repair requiring craniotomy.
When would a nerve graft code be more appropriate?
Use a head-and-neck nerve graft code when the operative reconstruction bridges a nerve defect with graft material rather than directly reconnecting the nerve ends. Codes 64885 and 64886 distinguish graft length.
Can modifier 50 be appended for repairs on both sides?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
What postoperative care is included?
The major-surgery global period includes the day-before preoperative visit and 90 days of related postoperative care.
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.
What documentation supports reporting 64864?
Document the injured extracranial nerve, the operative findings, and the repair performed. The record should distinguish direct nerve repair from graft reconstruction or nerve transfer.
