Colorado's Hospital Discounted Care law (HB21-1198): for qualifying patients with household income at or below 250% of the federal poverty level, hospitals and the clinicians who work in them may charge no more than the greater of the Medicare rate or the Medicaid base rate, and monthly payments are capped. That can be less than the cash prices below; ask the hospital to screen you for discounted care. 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
