<prompt> Human: Months ago my son had to be flown to an out of state hospital via air ambulance. The company charged 60,000 and our insurance only covered 20,000, leaving us with a 40,000 bill. We have appealed the claim but havent had any luck. We are planning to meet with the ambulance company to negotiate a payment plan soon. Any advice?  <response>: why not ask your insurance to cover more? what are they saying?
