Please call. I case was pending with my insurance until I called and found out there were things 'missing' (like a particularly worded sentence from my doc in her letter of recommendation and that my insurance wants three nutrition visits over 90+ days - mine were over a period of 71 leaving me short) from my file causing my surgery date to be pushed back. You don't want to get your ducks in (take off from work, help with kids, etc) only to be short changed in the end.
