CMS Price Transparency

CMS Hospital Price Transparency Enforcement

Centers for Medicare & Medicaid Services (CMS) · Tier-2 · profile-enrichment (renders on matched profiles)

Live
Source:CMS Price Transparency·Checked May 2026Open official source ↗

The CMS Hospital Price Transparency Enforcement dataset records every enforcement action taken under 45 CFR § 180 (the Hospital Price Transparency rule, effective January 1, 2021). It covers all hospitals subject to the rule — general acute care, critical access, and specialty hospitals — and tracks the full enforcement arc from initial warning through corrective action plans, civil monetary penalties (CMPs), and final resolution. As of 2026, the dataset spans 11,440 enforcement actions across 4,988 unique hospital review cases.

What Fonteum uses it for

How this source shows up on Fonteum.

Powers the /research/hospital-price-transparency-compliance-2026 flagship study and the /data/price-transparency dataset page. Enables per-state enforcement density analysis, CMP recipient identification, and compliance trend mapping.

What this source does NOT mean

This dataset records CMS enforcement actions — it does not contain the hospitals' actual machine-readable files (MRFs) or the price data itself. An action does not represent a finding of ongoing non-compliance; hospitals that completed corrective actions appear as 'Met Requirements'. Fonteum does not editorially rank hospitals based on enforcement history.

Fields used

Limitations

What we can’t infer from this source.

  • Snapshot-based: the dataset reflects enforcement actions as published at each monthly CMS release; actions finalized after the snapshot date do not appear until the next pull.
  • Hospital identity is name + address string — no NPI or CCN in the raw CMS export. Cross-referencing to NPPES or Care Compare requires fuzzy matching.
  • A hospital with multiple review cycles appears multiple times with distinct Case_IDs; the same hospital may show both 'Warning Notice' and 'Met Requirements' actions in the same snapshot.
  • Enforcement actions are CMS determinations of regulatory compliance under 45 CFR § 180; they do not reflect clinical quality, financial health, or patient outcomes.
