Centers for Medicare & Medicaid Services (CMS) · Tier-2 · profile-enrichment (renders on matched profiles)
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.
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.
Research and data questions this source supports.
- Map per-state hospital price-transparency enforcement density to see where CMS has concentrated its 45 CFR § 180 actions.
- Identify hospitals that received a civil monetary penalty (CMP) under the Hospital Price Transparency rule, and which later reached 'Met Requirements'.
- Track the compliance trend across the full enforcement arc — warning, corrective action plan, CMP, resolution — since the rule took effect January 1, 2021.
- Reproduce the /research/hospital-price-transparency-compliance-2026 study with the underlying enforcement records and source provenance.
- Support hospital M&A or compliance diligence with a hospital's documented CMS enforcement history.

Research-only — never on profiles
7 fieldsWhat 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.

Common questions about CMS Price Transparency.
- What is the CMS Hospital Price Transparency Enforcement dataset?
- It is the federal record of every enforcement action CMS has taken under 45 CFR § 180, the Hospital Price Transparency rule effective January 1, 2021. It covers general acute care, critical access, and specialty hospitals subject to the rule and tracks the full arc from initial warning through corrective action plans, civil monetary penalties, and final resolution.
- How many enforcement actions are in the dataset?
- As of the 2026 snapshot, the dataset spans 11,440 enforcement actions across 4,988 unique hospital review cases. A single hospital with multiple review cycles appears multiple times with distinct CMS case IDs.
- Does this dataset contain hospital prices?
- No. The dataset records CMS enforcement actions — not the hospitals' machine-readable files (MRFs) or the price data itself. An enforcement action is a CMS determination of regulatory compliance; it does not reflect clinical quality, financial health, or patient outcomes.
- Does an enforcement action mean a hospital is non-compliant today?
- Not necessarily. Hospitals that completed corrective actions appear with a 'Met Requirements' action, and the same hospital may show both a 'Warning Notice' and a 'Met Requirements' record in the same snapshot. Fonteum does not editorially rank hospitals based on enforcement history.
- Where does the data come from and how often is it updated?
- CMS publishes the enforcement dataset at data.cms.gov as U.S. government public-domain data (17 U.S.C. § 105); no API key is required. Fonteum re-pulls on the 1st of each month and attests each snapshot with a SHA-256 hash.
