Highest prices compared to Medicare

What this means for your bill

List prices are a starting point, not what insurers pay. But uninsured patients and people paying a deductible are often billed from them. A high multiple is a strong reason to ask for an itemized bill and question the charges.

How this is calculated

For each hospital we compare the gross charges in its federally required price transparency file with what Medicare pays hospitals for the same billing code (the outpatient OPPS rate), then average across procedures. Codes Medicare doesn’t pay that way, such as lab tests and inpatient surgery, are left out. Hospitals need at least 5 priced procedures to be ranked. Full method and grading scale.
