How to read this index

Sourced, dated, free to cite

Specialty classifications come from the CMS NPPES taxonomy — the federal record of how each provider self-classifies. We report that record and its limitations; we do not certify providers or assert facts a public source cannot support. Browse the data catalog, review every registered source, or read the methodology.[1]
  1. [1]CMS National Provider Identifier (NPI) registry / NPPES — provider taxonomy classification (NUCC Health Care Provider Taxonomy).

Built on the authoritative federal record

The primary sources, named on every page.

These are the federal agencies whose public datasets Fonteum ingests and attributes — the issuing authorities, not customers or partners. Every figure on the site links back to one of them.

  • HHS-OIG
  • HRSA
  • FDA
  • NLM
  • NUCC
  • Census

Reproducible by design

Published figures name their source and date.

Source and date

Published research identifies its government file and observation date. Source-file SHA-256 coverage is disclosed separately; facts do not currently link deterministically to signatures.

Reproducible SQL

Each study ships the exact query behind its figures, run against the same dated copy of the federal file we used. Re-run it yourself.

Daily observations

The platform records table row counts daily. Those observations detect local drift; they do not imply that an upstream publisher released or Fonteum ingested new data that day.
