About 64505: Sphenopalatine ganglion anesthetic block
Reports delivery of anesthetic to the sphenopalatine ganglion, often for headache or facial pain when that ganglion is the treatment target.
This service places anesthetic at the sphenopalatine ganglion to temporarily interrupt pain signaling. It is commonly used for selected headache syndromes, including cluster headache, and some facial pain conditions. Pain physicians, anesthesiologists, neurologists, or other qualified clinicians may perform the block in an office or procedure setting. A transnasal approach is common; the documented technique should show that the ganglion, rather than another nerve or nasal structure, was targeted.
Report the code when the service is directed to the sphenopalatine ganglion. Documentation should identify the indication, side, approach, and anesthetic delivery. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

64505 billing questions
How is this different from a trigeminal nerve block?
Use this code when the sphenopalatine ganglion is the anesthetic target. A trigeminal nerve block is selected when the clinician targets a trigeminal nerve or branch instead.
What documentation supports reporting the block?
Record the clinical indication, the sphenopalatine ganglion as the target, the side treated, the approach, and anesthetic delivery. The note should distinguish the ganglion block from anesthesia applied to nasal tissue alone.
How should bilateral treatment be reported?
CMS identifies this as a bilateral procedure; report modifier 50 for bilateral service. CMS pays bilateral reporting at 150%.
Are same-day preoperative and postoperative services included?
Yes. The code has a 0-day global period, which includes same-day preoperative and postoperative care.
Can an assistant or co-surgeon be reported?
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?
The highest-valued procedure is paid in full; 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.
