FAQ

Do I need an API key? No. The NPPES NPI Registry API is publicly accessible without authentication. This actor handles all requests on your behalf.

What is an NPI number? The National Provider Identifier is a unique 10-digit identification number assigned to every healthcare provider in the United States. It is required for billing Medicare, Medicaid, and most private insurance. Every licensed provider who transmits health information electronically must have one.

What is the difference between NPI-1 and NPI-2? NPI-1 is assigned to individual providers (doctors, nurses, therapists, dentists). NPI-2 is assigned to organizations such as hospitals, group practices, and clinics. Both types are searchable.

How many providers are in the registry? The NPPES registry contains over 7 million active NPI records, covering every type of licensed healthcare provider in the US.

Can I search by specialty? Yes. Use the taxonomyDescription field with any specialty term (e.g. "Cardiology", "Family Medicine", "Psychiatry", "Physical Therapy"). The search supports partial matches.

How current is the data? The NPPES registry is updated weekly by CMS. This actor queries the live API, so results reflect the current registry state.

Can I use this for HIPAA-compliant workflows? NPI data in the NPPES registry is public information. There is no HIPAA restriction on using or distributing NPI numbers and the associated practice information, as this data is intended to be publicly accessible for billing and credentialing purposes.
