Fonteum — Provider data with source lineage attached to every field.
Fonteum publishes source-backed provider datasets and dated research snapshots, all anchored on federal public-record sources (CMS NPPES, CMS PECOS, CMS Care Compare, BLS, Census, HRSA, OIG LEIE). Every cited fact carries source · last-checked date · limitations. A FHIR R4 API is in beta — pilot pricing available; the paid tier also ships through the Audit Pack export endpoint within Fonteum — see /audit-pack and /data-platform/pricing for the Fonteum pilot/standard/ enterprise contract.
Free to cite with attribution. License inquiries: press@fonteum.com.

Rows
3,039 rows
Last cataloged May 8, 2026. Each dataset includes a methodology block on its corresponding study page. License: free to cite with attribution.
Every exported field carries the same four pieces of provenance.
This is the contract a B2B buyer is paying for when they license an Fonteum export — not a row count. The same four-field contract drives the visible ProvenanceCard on every public profile.
source name
The originating public-record dataset for this field — never an inferred or scraped substitute.
e.g. CMS NPPES · CMS PECOS · CMS Care Compare Provider Data
last checked
ISO date the Fonteum pipeline last reconciled this field against the source. Stale rows fall out of the export.
e.g. 2026-04-30
confidence
Which Fonteum confidence tier (high · medium · low) the row sits in. Low-confidence matches do not ship in B2B exports.
e.g. high (NPPES taxonomy + state + name match)
display permission
Whether the source's terms allow public republication, attribution-only display, or write-locked access only.
e.g. public · attribution required
Concepts, scoped via email — not shipped products.
The five exports below are the kinds of dataset Fonteum can scope and price for a B2B research or enrichment use case. Every export carries the four-field source-provenance contract above. None of these is on disk today — scoping happens via email.
- Concept · scope by request
Dermatology provider export
Per-practice rows with NPPES NPI + provider taxonomy + CMS PECOS Medicare-enrollment indicator. Source citation + last-checked date on every field.
- NPI · taxonomy code · taxonomy description
- PECOS enrollment status · CMS provider type
- Practice address (NPPES)
- Provenance: source · last-checked · display rule
- Concept · scope by request
Chiropractor provider export
Per-practice rows for chiropractors built on the same NPPES NPI + taxonomy + CMS PECOS enrollment contract as the derm export. Doctrine line preserved — we never assert blanket licensure.
- NPI · taxonomy 111N… (chiropractic)
- PECOS enrollment status · CMS provider type
- Practice address (NPPES)
- Provenance: source · last-checked · display rule
- Concept · scope by request
CMS Care Compare facility quality export
Per-state and per-facility CMS Care Compare snapshots — nursing home, home health, dialysis, hospice. Includes the CMS-published rating, ownership type, and certification metadata.
- CMS Certification Number
- Overall star rating · component sub-ratings
- Ownership type
- Source: CMS Care Compare Provider Data
- Concept · scope by request
Home-health state quality dataset
State-level aggregates from the CMS Care Compare Home Health Care Agencies dataset — quality-of-patient-care star rating distributions, rated/unrated counts, ownership mix.
- State-level mean star rating
- Rated vs unrated agency counts
- Ownership mix (For Profit / Non Profit / Government)
- Source: CMS Care Compare Home Health (6jpm-sxkc)

Request a sample export →The doctrine guardrails on this product.
Same wording lives on /editorial-policy#doctrine and /llms.txt. The data product inherits the same claim-ceiling.
We do not sell pre-screened provider lists.
Pre-screening implies a human or process check we don't perform. Our provider data is source-cited, not pre-vetted. Buyers expecting a quality stamp on each provider should look elsewhere — see /editorial-policy for the full claim-ceiling doctrine.
We do not resell restricted source data.
Where a source's terms restrict redistribution (e.g. some state-board exports, state-bar registries, NMLS Consumer Access, ABMS / CertiFacts), we cite the source publicly but do not include those rows in any export. Every dataset is built from public-record data we have explicit license to redistribute with attribution.
We do not provide patient or customer data.
Fonteum does not collect, hold, or sell patient records, claim records, or end-consumer behavioral data. The exports are provider-level public-record data only.
We do not backfill from Google Places.
Where a study's universe needs to be expanded, we expand it from the federal public record (CMS NPPES, CMS PECOS, CMS Care Compare). We do not pad the dataset with Google Places listings unless explicitly noted on the study page.
We do not claim full market census.
Even on source-backed verticals, our exports cover only the providers in the source's published universe. Treat counts as the floor, never as a definitive market headcount.
