On pre-existing conditions:
As I understand it that's not an outright "given". I read something about a panel of, I believe it was 26 people, only ONE of whom is required to be a practicing doctor, would make the final decision on a pre-x.
What struck me about that was this "panel" would have to over see so many cases it would be all but impossible for them to do so? I would imagine they would only see the cases that are involved in a law suit or are high profile. Who would make the day to day decisions in reality for the bulk of the people remains unanswered.
Edit:
Found the article I was referring to above, here's the link to Tommy De Seno's take on it.
