Minnesota law (Minn. Stat. §144.589): a hospital may not charge an uninsured patient whose household income is under $125,000 more than the lowest amount it would be paid for the same service by a private insurer, counting the insured patient's share. If the cash price below is higher, ask the billing office to apply this limit. Each hospital's page here shows the range of insurer rates in its own file (the "Insurers pay" column), a starting point when you ask. Other states' laws.

Hospital The hospital that published the price, its city and the line exactly as written in its price file.
Cash price The hospital's own price for a patient paying without insurance (“discounted cash” in its price file). Hospitals must publish it under federal law, 45 CFR 180.50. Call to confirm it before booking. More
List price The hospital's full chargemaster price (“gross charge”) before any discount. Almost nobody pays it; the gap to the cash price shows what the self-pay discount is worth. More
File date When the hospital last updated its price file, as the file says itself. A dash means the file gives no date.
No cash discount This line's cash price equals the hospital's full list price. Many hospitals still reduce bills for uninsured patients: ask the billing office for its self-pay discount in writing. More
