> Health insurance companies cannot refuse coverage or charge you more just because you have a “pre-existing condition” — that is, a health problem you had before the date that new health coverage starts.

>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, as well as pregnancy.

>They cannot limit benefits for that condition either. Once you have insurance, they can't refuse to cover treatment for your pre-existing condition.

This has been in effect since 2014 due to the Affordable Care Act.
