If your rates went up, but your previous coverage was never actually put to the test in a serious way you might want to consider the very real possibility that the old plan never would have paid out [1].

"Since insurance companies now won’t be allowed to collect premiums while you’re healthy only to yank coverage when you get sick, they have no choice but to pre-emptively cancel plans that wouldn’t be financially beneficial to actually pay out."
