So, I contacted my insurance company today about the $23,000 helicopter bill. They said that the helicopter company had not filed a pre-certification so they denied their claim. They said I am not responsible for the bill. After I meet my $5000 deductible (I've apparently already met that), they will pay the rest. But the helicopter company would have to file the correct paperwork and resubmit. If they try to bill me directly, I should send it to them. This is different than what they told my husband the first time he called (that there was a $1000 limit on transport). I think the medically necessary part must trump that. Anyway, I AM RELIEVED! We haven't gotten all the bills yet. Don't know how long that will take and if there will be any more surprises. But $5000 sounds a lot better than $5000 plus $23,000.
