Illinois law (Hospital Uninsured Patient Discount Act, 210 ILCS 89): an uninsured Illinois resident with family income up to 600% of the federal poverty level (300% at rural and critical access hospitals) can apply for a discount that brings the bill down to about 135% of the hospital's cost; up to 200% (125% at rural hospitals) medically necessary care is free. A hospital may collect no more than 25% of family income in 12 months. Ask the billing office for the application. 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
