Pain management
About 64400: Trigeminal nerve injection or block
Reports an injection around a trigeminal nerve division or branch, commonly for facial pain or trigeminal neuralgia treatment or diagnostic evaluation.
This service places an anesthetic, with or without a steroid, around a trigeminal nerve division or branch to evaluate or relieve facial pain. Pain medicine physicians and anesthesiologists commonly perform it in an office, pain clinic, or outpatient facility. Typical situations include a diagnostic block or treatment directed at trigeminal neuralgia or another facial pain condition. The documented target must be part of the trigeminal nerve, not another cranial or peripheral nerve.
Report the service when the clinician performs the trigeminal injection; document the indication, targeted division or branch, side, and injectate. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral service, modifier 50 is paid at 150%. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others at 50%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.

64400 billing questions
When should 64400 be selected instead of a general peripheral nerve block code?
Use 64400 when the documented target is a trigeminal nerve division or branch. A different peripheral nerve target calls for the code specific to that nerve, when available.
Does the code identify the facial pain diagnosis by itself?
No. The record should support the indication for the injection and identify the trigeminal division or branch treated.
How is a bilateral trigeminal injection reported for Medicare payment?
Use modifier 50 for a bilateral procedure; CMS pays it at 150%.
Is same-day pre- and postoperative care separately included?
The code has a 0-day global period, and same-day preoperative and postoperative care is included.
Can an assistant, co-surgeon, or surgical team be reported for this service?
CMS does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
What happens when another procedure is performed in the same session?
CMS pays the highest-valued procedure in full and the other procedures at 50% under the standard multiple procedure reduction.
