Protecting uninsured patients from high hospital charges: lessons from California.

Key findings. (1) In 1997, the amount California hospitals billed uninsured patients was more than twice the amount hospitals received from Medicare for the same services. By 2010, billed charges had grown to be five times what Medicare paid, which trans­lated into a gap of more than $10,000 per day in the hospital. (2) Five years after the passage of the state's Hospital Fair Pricing Act, most California hospitals had financial assistance policies in place to make care more affordable for the state's uninsured population. (3) As of 2011, 81 percent of California hospitals reported charging low-income uninsured patients prices that were at or below Medicare rates. (4) While not required by the law, nearly all California hospitals reported offering free care to uninsured patients with incomes at or below 100 percent of poverty.
