Hospital Price Transparency Enforcement: 11,440 CMS Actions Since 2021

Key findings

Five years of federal enforcement

The Hospital Price Transparency rule (45 CFR Part 180) took effect on January 1, 2021, requiring every hospital operating in the United States to post a machine-readable file (MRF) of their standard charges and a shoppable services list. CMS has the authority to issue Warning Notices, request Corrective Action Plans (CAPs), and — for the most egregious or repeat violations — issue Civil Monetary Penalties of up to $300 per day for hospitals with fewer than 30 beds and up to $5,500 per day for larger facilities.

This analysis covers every enforcement action in the public CMS dataset from the rule’s effective date through March 31, 2026: 11,440 actions across 4,988 unique review cases.

The enforcement arc has three phases:

• Phase 1 (2021–2022): Voluntary compliance emphasis. CMS issued relatively few formal enforcement actions while hospitals scrambled to understand technical MRF requirements. The agency signaled it preferred correction over sanction.
• Phase 2 (2023–2024): Escalation begins. As the compliance deadline extended and repeat violators emerged, CMS began issuing CAP requests and the first CMPs. Warning Notice volume grew substantially.
• Phase 3 (2025): Peak enforcement. With 5,432 actions in calendar year 2025 — more than the prior three years combined — CMS made clear that the voluntary compliance window had closed.

Enforcement action breakdown

CMS uses a sequential enforcement framework. A hospital typically receives a Warning Notice first, then a CAP Request if it does not correct the violation, and ultimately a CMP if it fails to comply with the corrective action plan.

State-level enforcement — top 20

Enforcement volume is driven by hospital market size, CMS review capacity, and compliance posture. Texas leads with 1,175 total enforcement actions and 5 CMP notices — the highest of any state. Louisiana, ranking 6th by total actions, has issued the second-most CMPs (3) relative to its enforcement volume.

Civil Monetary Penalties: the 28 cases

CMPs are CMS’s most powerful enforcement tool under 45 CFR § 180.90. As of the March 2026 snapshot, 28 CMP notices have been issued since the rule took effect — a number that may seem modest but carries significant financial consequences: penalties up to $5,500 per day for large hospitals compound quickly.

CMS does not publish penalty dollar amounts in this dataset; the enforcement action record indicates only that a CMP Notice was issued. The statutory maximum of $5,500/day means a hospital in violation for 180 days faces a potential penalty of $990,000.

The 28 CMP recipients are concentrated in states where Warning Notices were not sufficient to compel action: Texas (5), Louisiana (3), Alabama (2), Arkansas (2), Florida (2), Georgia (2), and one each in California, Illinois, Indiana, New Jersey, New York, North Carolina, Pennsylvania, and Virginia account for 15 of the 28 CMPs.

What this dataset does not capture

• No actual price data. This dataset records the enforcement action, not the hospital’s pricing.
• No NPI or CCN. The CMS export does not include National Provider Identifiers or CMS Certification Numbers; cross-referencing requires fuzzy matching.
• No financial penalty amounts. CMP notices appear in the dataset, but the dollar figure assessed is not published in this file.
• Federal enforcement only. Several states have enacted their own hospital price transparency laws; state enforcement actions do not appear in this dataset.
• Single-snapshot action records. Understanding a hospital’s full resolution arc requires grouping by Case_ID and ordering by date.

Frequently asked questions

What is the Hospital Price Transparency rule?

The Hospital Price Transparency rule (45 CFR Part 180) requires U.S. hospitals to publish a machine-readable file of their standard charges for all items and services. It took effect January 1, 2021. CMS enforces compliance through Warning Notices, Corrective Action Plans, and Civil Monetary Penalties.

How many hospitals have received a Civil Monetary Penalty under the Price Transparency rule?

As of the March 2026 CMS snapshot, 28 CMP notices have been issued since January 2021. Texas hospitals received the most CMPs (5), followed by Louisiana (3). CMP penalties can reach $5,500 per day for large hospitals.

Which states have the most hospital price transparency enforcement actions?

Texas leads with 1,175 total enforcement actions, followed by California (970), Florida (686), Ohio (414), and Pennsylvania (409). High totals generally reflect large hospital markets; however, CMP concentration in states like Louisiana and Alabama suggests some smaller-market states have disproportionate non-compliance rates.

Does a CMS enforcement action mean a hospital is currently out of compliance?

Not necessarily. The dataset records every action taken — including 'Met Requirements' determinations that indicate the hospital came into compliance. Researchers should group by Case_ID to see the full enforcement arc: a hospital may appear in both a 'Warning Notice' row and a subsequent 'Met Requirements' row.

Why did enforcement actions spike in 2025?

CMS announced expanded enforcement capacity in late 2024 and clarified technical MRF requirements. The 2025 surge (5,432 actions) processed a significant backlog of outstanding cases while also initiating new reviews. The corresponding increase in 'Met Requirements' determinations in 2025 confirms CMS was resolving existing cases, not only opening new ones.

Methodology

Data source: CMS Hospital Price Transparency Enforcement Activities and Outcomes dataset (dataset ID: 6a3aa708-3c9d-411a-a1a4-e046d3ade7ef). Published at data.cms.gov. Coverage: all hospitals subject to 45 CFR Part 180, effective January 1, 2021.

Snapshot date: 2026-03-31. Monthly updates; Fonteum re-pulls on the 1st of each month via the data-api/v1 endpoint.

Aggregation: Total and per-action-type counts were computed by grouping on the State and Action fields across all 11,440 rows. Year-over-year totals were derived from the Action_Date year component.

Methodology version: price-transparency/v1

Limitations

• Snapshot-based: enforcement actions added after the monthly snapshot do not appear until the next pull.
• Hospital identity in the CMS export is name + address string — no NPI or CCN, limiting automated cross-referencing to provider registries.
• CMP dollar amounts are not published in this dataset; only the existence of a CMP Notice is attested.
• A hospital may appear with multiple Case_IDs across separate review cycles; the dataset records enforcement actions, not current compliance status.
• Federal enforcement only; state-level price transparency enforcement actions are outside the scope of this dataset.
• The 'Appealed' action type does not indicate outcome — the dataset does not record appeal results.
