Mercy Medical Center Inc

301 Saint Paul Place, Baltimore, MD 21202 · (410) 332-9237

Charges close to what care is actually paid for

For every $1 of care Medicare actually paid for here, Mercy Medical Center Inc billed $1.15 in list charges. That gap does not change a Medicare patient's bill — but it is where an uninsured or out-of-network bill starts.

How this grade was reached

Each component is scored against every other U.S. hospital in the same federal files, so the grade is a position in the country, not a pass mark we invented.

Inpatient charge markup 33.3/35

Better than 95% of U.S. hospitals.

Outpatient charge markup 12.5/25

Not published for this hospital — scored at 50% of the component rather than zero, because an absent figure is not a bad one.

Price level vs national median 28.5/30

Better than 95% of U.S. hospitals.

Price consistency 9.1/10

Better than 91% of U.S. hospitals.

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.
