I happened to have an appointment schedule. I went into the clinic and, since it was my first time there, I filled out a stack of paperwork. And then they told me my insurance was inactive.
So I figured, whatever, I'll pay it out of pocket and file for reimbursement. I asked how much the specific service I was requesting would cost. And they had no idea. They refused to tell me, other than to say "well, we charge a hundred dollars up front and then you pay the rest of the bill after you are done".
I ask to see their cash price list, because every sane facility I've ever been to has a cash price list with prices that are 1/2 to 1/4 of the insurance price. And they don't have one.
So I ended up leaving. It's amazing just how perverse health insurance has become, that it can so affect the delivery of medical care that the facility cant/wont give an up front estimate.
I wasnt even there for anything complex - just a standard glucose diabetes test. They probably do ten a day.
