From what I have seen you'll be one of those people the Democrats used to feature in their advertisements about how anybody could go bankrupt as a result of an illness or injury.
It is hard to get detailed policy documents, but the materials I have seen say that you'll be covered for urgent care or an emergency room visit. But not for any further care. As far as I can tell that means you are out of luck if you need to be admitted to a hospital, or see specialists.
From what I've gathered, the exchange policies in my state are going to cover only true emergent care when out of area or at a non-network provider, basically similar to EMTALA requirements. No urgent care or "soft" emergencies.
