Saying Known issues are covered is meaningless.
The only response to this is to either sue them or switch coverage because they have failed to provide the services you have paid for.
The sentiment "American Healthcare isn't as bad as people say it is!" has become a defense mechanism.
As in, its purpose is not to ensure that a discussion is reasonable, but to make the speaker feel both superior to, and insulated from, the problems killing fellow human beings.
Pretty sad.
As a different anecdote, Anthem paid all of my cost for an ER visit last year (minus deductible). It was a first time thing. That's why your parent was asking you to avoid hyperbole.
Yes, if you are actually having a heart attack or a bone is sticking out then sure they cover you. The problem is in situations where you don't know and need medical experts to chose if this is an actual emergency. And no this is not hyperbole, that's the exact situation people in these states are dealing with.
This is not call them up on the phone and they say you can go to the ER, this is you go to the ER they preform tests and then the insurance company uses those results to deny clams.
Keeping heated discussions honest is important, regardless of which side you are on (and I'm on your side).
B) What time was this because it's a recent change?
Based on the article I suspect your experience has little barring on this situation.
