So instead of going to Simon med I had my obgyn send the orders for my ultra sound to east valley diagnostic center (Evdi) and I didn't have a co pay! And Simon med wanted me to pay an upfront cost of 55 bucks and EVDI only charged me 28 bucks! Talk about how Simon med over estimates charges and hey would've owed me back. Who would've known how much time it would take me to get my cash back. While they collect the interest on e money hey owe me. If you want to go to a imaging center that doesn't have a crappy pay first policy go to Evdi and there is no wait!
