Why New Jersey prices look low: under state law (P.L.2008, c.60), a hospital may not charge an uninsured New Jersey resident whose family income is below 500% of the federal poverty level more than 115% of what Medicare pays for the same service. If that is you, ask the hospital's billing office to apply this limit; a separate physician fee may still apply. 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
