Not in the US, but I've a close friend of mine who got rejected for an health insurance cause he's slightly overweight (and other people for preexisting conditions)
I'm not sure how that is in the US, but the abuse can come from anywhere and the result is likely to be worst that what they claim to be helping preventing.
> Health insurers can no longer charge more or deny coverage to you or your child because of a pre-existing health condition like asthma, diabetes, or cancer. They cannot limit benefits for that condition either. Once you have insurance, they can't refuse to cover treatment for your pre-existing condition.
I'm happy to see that is not the case in the US, but my was a general comment non necessary related to the US. But the fact that they're till law in the US presuppone that insurance company were behaving they way before.
