Need an ambulance? Depending on the state, it will cost you

Although the U.S. outlawed most surprise medical bills starting this year, people who face a health emergency could still find themselves on the hook for hundreds of dollars — or more — in out-of-network fees.

For patients with health insurance, an ambulance ride can set someone back between $500 and $1,000, according to a report from the Public Interest Research Group released Tuesday.

"Ground ambulances are the highest out-of-network biller of all of our health care services," Patricia Kelmar, PIRG's senior director of health care campaigns, told CBS MoneyWatch.
