How your money goes farthest

Move 1. Call the cheapest facility first and say “self-pay.” Ask for the all-in self-pay price and whether the doctor’s fee and anesthesia are included, since hospital prices often cover the facility only. Independent surgery and imaging centers usually run far below hospital rates for the same code.
Move 2. If it must be a hospital, use your financial-assistance rights. Nonprofit hospitals are required by federal law to have a financial assistance policy, and you can apply up to 240 days after the first bill. Ask billing for the “financial assistance application” before you pay anything, and bring the lower prices on this page with you.
