Glad the info helped. Since it looks like you might go the out-of-network route, I just wanted to follow up with the fact that I've had some difficulties with that process...
They say they can accept no other method of submission other than paper forms through the mail. And then when I followed up with a phone call, they said it takes 2-3 weeks just to get the forms in the system so you can check on the status. I'm still very hopeful, because I like my opthamologist and he is out-of-network. But it looks like it could take a while. Just FYI.
