Price-transparency record

CMS's enforcement list records these actions for a hospital named City of Hope Helford Clinical Research Hospital in Duarte, CA, under the federal hospital price-transparency rule (45 CFR part 180), which requires hospitals to post their standard charges online:

Warning Notice — 2024-11-05 (CMS case 2858)
Closure Notice — 2025-02-14 (CMS case 2858)

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.
