Every public-record source that powers Fonteum.

We match dermatology and chiropractic practice listings to NPPES records and surface the NPI, taxonomy code, taxonomy description, and NPI enumeration date on the profile. Each value carries source attribution + last-checked date + the §95 limitations sentence.

We cross-reference NPPES-matched healthcare practices against PECOS to surface a Medicare-billing-active indicator on the profile, alongside the CMS provider type and enrollment state. The display module is gated to medical archetypes only.

Exclusion status check on provider profiles: any NPI in oig_leie_exclusions surfaces a compliance flag on the profile with exclusion type, date, and reinstatement date where applicable. Powers the brand-hub /sanctions surface.

Deterministic CCN identity backbone. Every cross-source join (Care Compare, PBJ, Deficiencies, LEIE, ownership) hangs off this CCN. Surface usage: brand-hub Care Compare modules + audit-pack export.

Identity backbone for Home Health Agencies (POS QIES does not cover HH). Drives the brand-hub `/care-compare/home-health` module. State-level rollups and per-agency pages ship in a follow-on wave.

Enrichment for hospice identity (POS QIES already covers hospices as PRVDR_CTGRY_CD=12; Care Compare adds ownership_type and cms_region). Drives the brand-hub `/care-compare/hospice` module. The May 2026 Training-Family-to-Care measure removal is documented in the methodology; quality-measure ingestion is a follow-on wave.

Identity backbone for ESRD facilities (POS QIES doesn't cover dialysis). Drives the brand-hub `/care-compare/dialysis` module. Chain-ownership concentration (~90% chain-owned) is relevant journalism material.

Identity backbone for ASC CCNs (POS QIES coverage incomplete). Deterministic NPI bridge (no NPPES fuzzy match needed) — match-confidence improvement vs other Care Compare datasets. Drives the brand-hub `/care-compare/asc` module. ASC-12 (7-day risk-standardized hospital visit rate) is the headline quality measure.

Audit-pack export continuum-completeness + cross-source resolver enrichment for hospital CCNs. Buyer pitch leverage rather than consumer SEO surface.

Audit-pack export continuum-completeness for post-acute care continuum (acute hospitals → LTACH → IRF → SNF → HH → Hospice).

Audit-pack export continuum-completeness; IRF CCN distinction is doctrinally relevant for cross-source joins.

Today: four published research snapshots — nursing homes, home health, dialysis, hospice — plus the source pack staged for future Tier-2 facility pilots. CMS overall star ratings and component sub-ratings render only when a facility-level vertical launches; until then the data is research-only.

Drives the brand-hub `/staffing` editorial surface. Per-facility daily-granularity nurse-staffing — the only CMS dataset that exposes this layer at facility resolution.

Drives the brand-hub `/ownership` surface. Direct backbone for the published flagship study at /research/private-equity-nursing-home-ownership-analysis. Fonteum surfaces missingness via DataAvailabilityState: OWNERSHIP_PCT_MISSING — the gap is the data product.

Drives the brand-hub `/deficiencies` surface. Per-citation transparency layer; NH Penalties sub-join surfaces in audit-pack export only.

Sub-join. Audit-pack export field for /deficiencies methodology-versioned customer exports.

Drives the brand-hub `/special-focus-facilities` surface. Per-facility SFF status flag joins to Care Compare NH Provider Information via CCN.

MIPS composite scores and payment adjustments render on individual provider profiles (NPI-matched) with full provenance (source · performance year · methodology version). Powers the brand-hub clinician-quality module and the dbt QPP mart. Data is surfaced as published by CMS; Fonteum does not independently score, weight, or rank clinicians.

Tier-2 profile-enrichment for Medicare-certified hospitals. Headline fields render on hospital profile pages with full provenance (source · vintage · fiscal-year boundary). Powers the brand-hub Hospital Margin Gap analysis (Tier 1 #23) and the FHIR Organization.contained financial extensions (queued separately).

Tier-2 profile-enrichment for FQHC sites. Joins to existing HRSA HPSA shortage designations via FIPS and to the NPI identity graph via CCN — enabling shortage + quality compound queries. Awardee-level clinical quality measures (CQ01–CQ10+) and staffing data render on FQHC facility profiles with full provenance.

The POS file provides the CCN backbone for all Care Compare facility joins. Facility name, type, address, state, and participation/termination dates render on Care Compare brand-hub pages with full provenance (source · quarter · methodology version). No NPI is included in the iQIES POS export; NPI cross-reference is deferred to the NPPES join wave.

Tier-1 research-only context for /research pages discussing healthcare access. HRSA HPSA designations cover Primary Care + Dental + Mental Health only; they do NOT cover dermatology, chiropractic, or specialty care.

Tier-1 research-only context for /research pages that discuss workforce supply, wage benchmarks, or per-capita density. OEWS data appears in study commentary and methodology footnotes — it does NOT attach to individual provider profiles.

Tier-1 research-only context for /research pages that discuss regional spending, healthcare-services GDP, or per-capita income. BEA data appears in study commentary — it does NOT attach to individual provider profiles.

Per-capita denominators in research studies (e.g. 'X dermatologists per 100,000 residents'). Tier-1 — appears in study tables and methodology, never on individual provider profiles.

Hosting Fonteum's own research deliverables: state-level CMS Care Compare snapshots, healthcare specialty supply studies (dermatology, chiropractor, NPPES specialty factory), and provider-supply benchmarks. Renders on /research and /press; never overwrites federal source attribution on a per-field basis.
