the hospital for treatment? What for and how much did it cost, regardless if you had to pay for it or your insurance did? I had to go to the ER last March for kidney stones. I took the ambulance and was in the ER for about 5 hours with waiting and treatment. I had one ct scan taken, blood work and was given a muscle relaxant. Total cost with ambulance, tests, meds, hospital and doctors fees was around $6000.
