In my town there is a fixed $500 medical transport fee. What care you receive enroute doesn’t change the fee. Insurance might or might not cover it. Medicare does, I know that.
$500. - that’s higher than ours I think. The city has both private and fire dept. ambulance services. I think they charge about the same - except the fire dept mostly gets stiffed when it comes to payment, unless it’s someone with medicare or medicaid. Or very good insurance. We were very fortunate to have been able to retain our very good insurance.
Anyway, very often the fire dept. ambulance gets a call from a “sick” person who insists on needing to go to the ER, only once there - they hop up and say they feel fine now! Then they wander off to carry on their day/evening. THOSE people never pay the ambulance bill. They use the ambulance for a taxi service.
