Where 1835N0905X sits
- Group: Pharmacy Service Providers — code 10 of 19 in the group
- Classification: Pharmacist 183500000X
- Specialization: Nuclear 1835N0905X
Choose 1835N0905X over the general Pharmacist code (183500000X) when the provider's training or certification is specifically in nuclear; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
1835N0905X 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 — the provider can still hold an NPI and use this code on claims to other payers.

Using 1835N0905X
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.
