the plans you see on the site today are those offering insurance for 2014 in your state. it's possible that the following year you'll see new options during open enrollment but for next year you'll need to select from those currently on the site. you are supposed to be able to see the provider networks when you shop but it's always a good idea to call your doctors directly to confirm if they are participating with the plan you want to buy.
right now almost all plan options in indiana are hmos. can we expect other plan type options? . if so when will these be communicated? will the providers in each plan be available on the healthcare. gov site or elsewhere?
