Price-transparency record
CMS's enforcement list records these actions for a hospital named Marian Regional Medical Center in Santa Maria, CA, under the federal hospital price-transparency rule (45 CFR part 180), which requires hospitals to post their standard charges online:
- Met Requirements — 2024-02-01 (CMS case 93)
- Met Requirements — 2025-06-10 (CMS case 5007)
A warning notice or corrective-action request is not a finding of wrongdoing; "Met Requirements" and closure notices record that CMS's review ended. Matched to this hospital by exact name, city and state.
Charges are the hospital's list prices averaged over its 2024 Medicare cases; payments are what those cases actually brought in. Neither is what you will pay. For a planned procedure, ask the hospital for its price estimate or, if you are uninsured or self-paying, a good-faith estimate.
