But this weirdness still happens when you have a combined entity like Kaiser. I went for a routine visit, and paid the $30 copay before the visit. After the visit, I get a bill for Ridiculous_Number_X - Ridiculous_Number_Y = $30. The "actual cost" of the visit and the "negotiated discount" are numbers that are obviously pulled out of someone's ass because they magically align so that I have to pay $30. And since everything was handled by Kaiser, how the hell could they not know before my visit that they would want $30 extra and just charge me $60 beforehand and be done with it?
