I realize this is an old post and I don't have too much new info, but will gladly tell you the little bit I do know.
According to Dr. Bowers, Kaiser tries to push all of their customers to Dr. Meltzer for this procedure and refuses to find for anyone else because they are out of network. I myself am hoping to work around this by getting a referral from my doctor who just so happens to be on the board for Kaiser in the state of CO.
I will have to let you know what else I learn after my appointment on 7/21.
