Medicare
CMS's taxonomy crosswalk links 2084P0800X to Medicare specialty 26 (Physician/Psychiatry) and Medicare specialty 86 (Physician/Neuropsychiatry). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 36,906 practitioners are enrolled under it nationally, and 20 other taxonomy codes map to the same specialty.

The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
