- 62 of 189 hospitals list a cash price equal to their full list price, with no self-pay discount.
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.
Outpatient cash prices, one line per hospital — its lowest listed price for code 84481. Prices for both sides of the body and inpatient prices are not mixed in. Collected Nov 8, 2026. See them on a map
