What happened
According to an Associated Press report on June 9, federal officials have sent warning letters or requests for transparency plans to 519 hospitals since April. Texas led with 42 letters, followed by California with 38 and Indiana with 34. Every state except Alaska had at least one hospital on the list. A senior administration official told the AP that enforcement will ramp up and more letters are likely.
Some recipients described their problems as minor. Ascension said 13 of its hospitals received letters over a technical error, and MD Anderson Cancer Center said CMS accepted corrected documentation after it fixed a date field. The American Hospital Association said most members have complied with this year’s requirements and that hospitals will keep working with the administration.
Why the bar is higher this year
The 2026 outpatient payment rule changed what a compliant file looks like, with enforcement beginning April 1. Hospitals must now attest that their standard charge data is complete and accurate, and the file must name the CEO, president or designated senior official responsible for that accuracy. The old estimated allowed amount field is gone. In its place, hospitals report the 10th percentile, median and 90th percentile allowed amounts, with counts, drawn from 12 to 15 months of remittance data. Files must also list the hospital’s Type 2 National Provider Identifiers.
Those changes move price transparency from a web team task into revenue cycle and compliance territory. Percentile calculations depend on clean remittance data, and an attestation signed by a named executive raises the stakes of any error.
The financial exposure
Fines remain uncommon. CMS has fined 28 hospitals since enforcement began, including ten in 2025 and one so far this year. Penalties scale with bed count and can reach $5,500 a day for the largest hospitals. The larger risk is reputational: a public warning list invites press coverage, payer scrutiny and questions from employers who are pressing for lower prices.
What leaders should do this month
- Confirm the named official. Make sure the executive listed in the file knows it and has reviewed the data.
- Test the percentile fields. Ask revenue cycle to reconcile a sample of reported medians against remittance records.
- Check every campus. Multi-hospital systems should verify that each licensed facility has its own current file and NPI list.
- Prepare a response plan. Decide who answers a CMS letter, and how quickly, before one arrives.
