Known limitations

  • Hospital identity is name + address string — no NPI or CCN. Cross-referencing to NPPES or Care Compare requires fuzzy matching.
  • CMP dollar amounts are not published in this dataset; only the existence of a CMP Notice is attested.
  • A hospital may have multiple Case_IDs across separate review cycles; compliance status must be inferred from the action sequence.
  • Federal enforcement only — state-level enforcement actions are not included.
  • Does not contain the hospitals' actual charge files (MRFs) or pricing data.

Frequently asked questions

What fields are included in the CMS Hospital Price Transparency enforcement dataset?
The CMS export includes 7 fields: Case_ID, Hosp_Name, Hosp_Address, State, Action, Action_Date, and Closure_Reason. No NPI or CCN field is present in the raw CMS data.
How often is the price transparency enforcement data updated?
CMS updates the dataset monthly. Fonteum re-pulls on the 1st of each month via the data-api/v1 endpoint and attests each pull with SHA-256.
Does this dataset include the actual hospital prices or charge files?
No. This dataset records CMS enforcement actions only — it does not contain the hospitals' machine-readable files (MRFs) or the price data itself. For actual hospital charge data, see the hospitals' published MRFs under 45 CFR Part 180.
What is a Civil Monetary Penalty under the price transparency rule?
A Civil Monetary Penalty (CMP) is the most severe enforcement action available to CMS under 45 CFR § 180.90. Penalties can reach $300/day for hospitals with fewer than 30 beds and $5,500/day for larger facilities. As of March 2026, 28 CMPs have been issued.
