Late but USA, wanted to share a personal experience. While at work I collapsed and had to take an ambulance to the hospital. I got sent the bills for everything. Including the ambulance ride. I stayed in the hospital overnight for observation. They couldn’t figure out what happened and I didn’t have symptoms anymore so I was discharged. Whole event cost maybe $500.
Here’s the kicker, I work(ed) as a paramedic for the ambulance company that transported me. I had insurance that was not from the company so prices were reasonable relative to what one would expect in the country. Had I been insured through work, well, the insurance provided by the company doesn’t cover transport by that company’s ambulance.
