Price-transparency record
No action in CMS's price-transparency enforcement list (July 2026) matches this hospital's exact name, city and state. That can mean CMS has not reviewed it, or that it is listed under a different name.
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.
