How long for approval
I have to tell you, I never worried much about insurance approval. I am sure that Liz would've called me had there been a problem. What I understand though, is that they don't put in for approval until 2-4 weeks before surgery because they only have a certain window of time that the insurance allows after approval (the surgery has to be done within a certain amount of time or they have to reapply). If there is a problem, Liz will let you know. You have enough to worry about.
