Insurance Call

I called the insurance company today and they have no changes. I wonder if I should call my PCP again. They are supposed to be faxing information to the insurance company. I hate to be a pain, but in the past they have shown the need for some follow-up. I am trying to be nice and not pester them. I know these things take time. Where is the line between responsible follow-up and being a pain in the butt?
