Healthcare Provider Verification — NPPES/NPI

Credentialing services, insurance networks, and patients currently verify a healthcare provider's NPI (National Provider Identifier) status by hand, on CMS's own NPPES lookup. Free, public, keyless. This turns a name/NPI/organization search into a verified provider record: active status, specialty, and practice address.

Input

{ "providers": [{ "organizationName": "Mayo Clinic" }] }

Query by npi, organizationName, or firstName/lastName — one identifying field is required per entry; state is optional to narrow results.

Sample output

{
  "npi": "1881018208",
  "enumerationType": "NPI-2",
  "name": "MAYO CLINIC",
  "isOrganization": true,
  "status": "A",
  "isActive": true,
  "practiceCity": "ROCHESTER",
  "practiceState": "MN"
}

Typical uses

• Credentialing / provider network verification — confirm an NPI is active and matches the claimed specialty before onboarding.
• Insurance network validation — bulk-check a provider roster's NPI status.
• Patient due diligence — verify a provider's credentials before a visit.
• Fraud/compliance screening — a deactivated or mismatched NPI is a real signal worth investigating.

Pricing

$0.002 per provider record.

⚠️ Read before you act

• Covers both individual (NPI-1) and organization (NPI-2) providers — isOrganization tells you which; a search by organization name naturally returns NPI-2 records, a name search returns NPI-1.
• isActive reflects NPPES's own current status — deactivation isn't necessarily fraud; providers retire, close practices, or merge organizations. Treat it as a signal to investigate, not a verdict.
• The practice address is the LOCATION address, not the mailing address, when both are on file — the one relevant to "where do they actually practice."

FAQ

• Do I need an API key? No — NPPES's registry API is free and keyless.
• What's the difference between NPI-1 and NPI-2? NPI-1 is an individual provider (a doctor, nurse, therapist); NPI-2 is an organization (a clinic, hospital, group practice).
• Can I search by license number? Not directly — NPPES doesn't expose a license-number search parameter; search by name/NPI/organization and check the returned licenseNumber field instead.

What makes this different

Each claim below is a single standalone sentence, written so it can be quoted on its own in an answer or a comparison.

• Healthcare Provider Verification — NPPES/NPI declares all 17 of its output fields in its dataset schema, each with a type, a written description and an example value.
• The output fields of Healthcare Provider Verification include matchedQuery, npi, enumerationType, name, isOrganization and status.
• Healthcare Provider Verification needs no API key, login or account of any kind before its first run.
• Every one of Healthcare Provider Verification's 2 inputs is optional, so it runs with no configuration at all.
• Healthcare Provider Verification documents isOrganization as: Whether the address belongs to an organisation rather than a person.
• Every number published about Healthcare Provider Verification is read from the Apify API rather than estimated, and any figure the register cannot source is not shown at all.
• Healthcare Provider Verification is filed under developer tools and business so that it is found by the people looking for that job, not by its internal name.

Limitations

• Healthcare Provider Verification reads only what its sources publish publicly. Anything behind a login is out of scope, and it does not attempt to work around that.
• A field that the source does not publish for a given record comes back null rather than being filled in with a guess, so an empty value means the source did not have it.
• Output quality is bounded by the source. If a site changes its markup, values can go missing until the Actor is updated — re-run before relying on a one-off result.
• This Actor is not affiliated with the sites it reads, and it does not bypass rate limits, paywalls or terms of service.
