What is the correct code for a glossopharyngeal nerve block 64402 or 64450?

The glossopharyngeal nerve is the ninth cranial nerve. Unlike for other cranial nerves, you won't find a specific CPT code for blocking the glossopharyngeal. Look at 64450 (Injection, anesthetic agent; other peripheral nerve or branch) as a possibility. You might check with your provider to see if they are OK with the "peripheral nerve" description.

Per CPT Code description: 64400- Injection, anesthetic agent; trigeminal nerve, any division or branch, This is specifically for Trigeminal nerve, its division or any branch, So cannot be used for Glossopharyngeal nerve.
I have also checked CPT Code 64450- Lay Description- The physician anesthetizes a nerve to provide pain control or blockage. The physician draws a local anesthetic into the syringe and injects it into the branch of the nerve to be anesthetized. This code is used to report nerve blocks of other nerves not specifically listed in this section. Per last line of Lay description this code can be used for other nerves not listed in the section for nerves. So CPT 64450 appears more appropriate code.
