State program in California
Hospital Fair Pricing Act (Health and Safety Code 127400 et seq.)
Every licensed general acute care, acute psychiatric, and special hospital in California must have a charity care policy and a discount payment policy. A patient can ask for help if they are uninsured (self-pay) or have high medical costs, and their family income is not more than 400% of the federal poverty level. Hospitals may choose to help people with higher incomes. With a discount, the bill is capped at about what Medicare or Medi-Cal would pay, whichever is greater. You can apply at any time, even after a bill goes to collections. Immigration status does not affect eligibility.
Income levels in the program are discount up to 400% of poverty level.
Applies to each licensed general acute care hospital, acute psychiatric hospital, and special hospital in California.
Apply to the hospital's financial assistance office. Each hospital's policies and applications are posted on its website and on HCAI's Hospital Fair Pricing Policy Lookup (https://hcai.ca.gov/affordability/hospital-fair-billing-program/hospital-fair-pricing-policy-lookup/).

It covers problems on or after January 1, 2022. It does not handle general billing disputes, price transparency, Good Faith Estimates, or bills from emergency room doctors.

Ask the doctor group's billing office for its discount policy. HCAI's complaint program does not handle emergency doctor bills.
Income levels in the program are discount up to 400% of poverty level.
Applies to emergency physicians who provide emergency medical services in a California hospital that provides emergency care.
Ask the emergency physician group named on the bill for its discount payment policy.

Notes
Free care at or below 200% of the poverty level, for both uninsured and insured patients. From 201% to 450% you pay a share of the bill, from 10% up to 60%. Insured patients pay that share of what they owe after insurance. Above 451% uninsured patients still get 30% off with no upper income limit, and insured patients get no discount. Patients below 450% never pay more than Medicare or Medi-Cal would pay. Approval lasts 180 days. The hospital may use an Experian credit screen to approve patients who do not finish an application. Patients in bankruptcy, homeless patients with no income, and patients who died with no estate can be approved without applying. To dispute a decision, write to the CFO within 30 days. You can also call (800) 753-0414 or email Billing@MammothHospital.com. The office is at 85 Sierra Park Road, Mammoth Lakes, open 8 am to 4 pm. The policy does not say whether savings are counted.
