Charges close to what care is actually paid for

What this page cannot tell you

  • It is not your bill. These are averages across Medicare patients. What you pay depends on your insurance, your plan's negotiated rate and your own case.
  • It is not a quality rating. A hospital with a high markup may be excellent, and one with a low markup may not be. We checked: across every U.S. hospital, markup and the CMS quality star rating barely move together.
  • A charge is not a cost. Hospitals do not collect their list charges from insured patients. The number matters because it is the opening figure on an uninsured or out-of-network bill.
  • Ask for the real number. Every U.S. hospital must publish a machine-readable price file and give you a written good-faith estimate on request.
