Sphenopalatine Ganglion Block with Medication Delivery

Question:

One of our physicians is using a device to deliver medication through the nose when a sphenopalatine ganglion block is performed under fluoroscopic guidance for patients with migraine headaches.  Can we report 64505 for this service?  If not, what is the best code to report?

Answer:

 There is no specific CPT code that accurately describes the service.  The code set includes CPT code 64505, which describes the injection of the sphenopalatine ganglion; however, it is inappropriate to report this code since an injection is not performed. Therefore, the unlisted code 64999, Unlisted procedure, nervous system, should be reported. 

Another variation on blocking the sphenopalatine ganglion is using a Q-tip to apply anesthetic topically through the nose. There is no specific CPT code for this procedure, which is best reported as part of the E/M service.
