Sorry to hear!
I wouldn't go through insurance for this. You'll still have to pay the deductable and your rates could go up.
Depending how it's cracked, it could be repairable. I've actually seen a shop repair a crack (not sure how they did it) but you couldn't tell it was ever cracked even on the inside. All I know is that it wasn't a filler, it was some kind of plastic weld.
Better to pay out of pocket, as much as that sucks
