I paid up front and in full for a surgery i had two years ago. I had a very clear conversation with the billing about the "up front" and "in full" and paid them prior to my surgery. To my amazment, a few months after the surgery i recieved a bill larger than the ammount i paid whoch depicted my bill as a "down payment." They even fradulently tacked on an insurance discount. I do not have insurance. If you can avoid this despicable and immoral institution get your surgeries done elsewhere. They will screw you.
