You are probably stuck with the bill if you have appealed numerous times unfortunatly. You may want to consult an attorney, that's "usually" free.

If you do infact have to pay this, send 10.00 a month. that's a show of good faith in paying, I have included that I am unable to make a payment of more than X dollars, if they cash your check in "most all" cases they are agreeing to the payback. You do need to resolve this somehow as this bill is something that can allow them to garnish your wages.

Depending on the distance to ambulance has to travel its can be an enormous amount of money.

Sorry this has happened to you.
