I understand, breast cancer and a new hip aren't a financial walk in the park either. If they had acted 15 years ago, how many thousands of people would have been saved from devastation while UHC alone paid out a $billion+ to execs?
I would try to figure any way possible to leave those holding the bills holding the bag, maybe the Dr. being the exception. Every time I think it's over, they bill me for something they forgot. I disputed $5 Tylenols and $$ blood pressure pills, which I never took and they dropped it. If you're on a co-pay ask for a copy of the insurance co. bill and payment, you may get it, you may not, but they will listen to you more attentively from that point on. I also got a signed advance estimate and confronted them when the bill to me was more than twice the estimate. I'm sure you've already learned some ins and outs that I haven't yet. Good Luck, I wish you well.
