Why Maryland prices look low: Maryland is the only state where a commission (the HSCRC) sets hospital rates for every payer, so its hospitals publish prices far below the rest of the country. A separate physician fee may still apply.
Maryland law (Health-General §19-214.1) requires hospitals to give free medically necessary care to patients with family income at or below 200% of the federal poverty level and to cut the bill by 75% up to 250% and 60% up to 300%. With medical debt above 25% of family income in a year, discounts reach up to 500%. Immigration status does not count. Ask the hospital for its financial assistance application. Other states' laws.
