Minnie - I am sure that you have called them to talk to them about it - but if you haven't been able to yet, you should. My insurance company denied payment for tests I received for my 1 year F/U saying it was out of network - when they had already paid for my surgery there and all of my other visits and tests. I called them and even though it took a while to straighten it out, it turned out to be their "mistake". Crazy, I know, but a good thing I called and made a stink!
