St. Joseph Mercy Hospital System, Ypsilanti MI Prices quoted for procedures on telephone less than actual, Internet

I was shocked to see an overcharge on my bill for a common procedure that is performed in many clinics.  I had a couple of friends call them.  The quotes over the telephone were much less than what they charged me.  It turned out that they made a "mistake" by using the wrong billing code.  They did not apologize but wanted me to feel sorry for them for making the mistake.  I can't say more detail because this is a small town and I have to get along with these people whom I see every day.  Just make sure that you get all quotes in writing and all procedures preauthorized as to cost by your insurance company.  The insurance company also said I was overbilled.
