Researching whether ACA Exchange policies will cover complications

I am pursuing surgery in Mexico mid November 2013 (next month). I have to buy a new individual health insurance policy on my state's exchange as soon as possible to start on January 1, 2014. My state is not going to cover bariatric surgery with exchange policies, but I did find out that our exchange policies will cover revisions to weight loss surgery if they are needed to correct a life-threatening condition.

A big boasting point of the various "exchange" policies and ACA in general is that pre-existing conditions can no longer be excluded from insurance coverage. I thought it stood to reason that if they HAVE to take me starting January 1 and if I JUST HAPPENED to have had VSG right before they take me on, then if I have a complication they can't refuse to take care of me.

A fellow sleever shared a spread sheet with all of the states' intended policies back in June 2013. I can't get the url to post right now but if you search Obamacare in the forums it will come up.

I welcome any research along these lines that anyone wants to share -- I am dying to buy a policy and get it in hand to look over because I know you can send them back after a few days and get a different one if you don't like the details. (I have tried to sign up for an exchange policy every day since October 1st... some days I have gotten further in to the process but I've always ended up with a "sign-up process failed -- try again" message so far. I figure it will work soon/eventually --so I will keep up with my daiily Quest , lol.)
