Help...Insurance Approval

Hello All....I am hoping someone can give me some advice on how to handle the insurance approval process. Mainly what I mean is do you keep calling after the paperwork has been submitted or do you just sit and wait? I really want to expedite this process and was hoping someone could offer some advice? Thanks!

I gave the insurance companay a week and called. Then I started to call every other day. I heard I was denied before the Dr's office. I appealed and won. Good Luck to you. Sharon
