The ambulance/hospital bill varies. Also his insurance, (assuming he has one) should cover some of it.
My friend got into a rollover accident where she had to be transported to the hospital and the hospital and ambulance bills came out to thousands of dollarssince she had no insurance. And in the end she came out with bumps and bruises seriously. But just because she got a ride and stayed in the hospital for sometime it racks up. And like I said, she didn't even have surgery didn't even use a bandaid. I think all she did was like an x-ray to check for brokenbones and soemthing to scan for internal injuries.
