Where 251S00000X sits
- Group: Agencies — code 2 of 15 in the group
- Classification: Community/Behavioral Health 251S00000X
Community/Behavioral Health has no specializations, so 251S00000X is the only code for it. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
251S00000X has no entry in the CMS Medicare Provider and Supplier Taxonomy Crosswalk. That usually means Medicare does not enroll this kind of provider under its own specialty — organizations of this type enroll, if at all, under a facility or supplier type rather than a practitioner specialty.

Using 251S00000X
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.
