I guess if 90k was the max you could pay, it might not make sense. After all, you are paying more than 90k over 3 years. You could just save the money and have savings if you didn't get ill. I bet it could be a lot higher than that though.
That $90k ran up much faster than that, even with shitty insurance paying at least some of it, and medical needs continued to accelerate for a while afterwards. Savings wouldn't have done a bit of good; it was rapidly exhausted. (That's not part of the $90k, either! It's on top!)

If the hospital is in-network, you're good.
