Frequently Asked Questions about Allergy & Immunology in Oro Valley

How do I check a Allergy & Immunology practitioner's license?

Each practitioner profile shows the NUCC taxonomy code and any state license number the practitioner reported to NPPES, plus a link to the Arizona licensing board lookup. NPPES entries are self-reported; current license status is published only by the state board.

Why is a practitioner missing from this list?
