FAQ

Common questions

Is Healthgrades or Zocdoc better for finding a new doctor?
They solve different problems. Healthgrades helps you evaluate providers through reviews and profile data; Zocdoc helps you book the one you've chosen. Many patients use both in sequence.
Does Zocdoc or Healthgrades have a public API for provider data?
Neither publishes a public open API for provider data. Zocdoc has an EHR scheduling integration API for partners, not a general-access provider data feed. For open programmatic access to federal provider records, CMS NPPES publishes a REST API at npiregistry.cms.hhs.gov/api with no key requirement.
How do Healthgrades and Zocdoc handle insurance eligibility?
Healthgrades shows self-reported insurance networks from provider profiles. Zocdoc confirms insurance acceptance at booking time through integrations with provider billing systems. Neither is a live real-time claims eligibility check — that requires a clearinghouse.
What is the underlying source for provider data on these platforms?
Both platforms rely primarily on self-reported provider information supplemented by state licensing records. CMS NPPES is the federal system of record for assigned NPIs and is publicly downloadable. Its administrative fields do not establish licensure or credentialing, and NPI joins work only where another source supplies that identifier.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
