California law (Health and Safety Code §127405): if you are uninsured or have high medical costs and your family income is at or below 400% of the federal poverty level, a hospital may not expect you to pay more than it would expect from Medicare or Medi-Cal, whichever is greater. That can be less than the cash prices below; ask the hospital for its discount payment policy. A separate physician fee may still apply. Other states' laws.
