I agree and have run into that myself. The plan names were distinguished only by a suffix. But the corporate site did include both and they were clearly described as exchange vs.non-exchange (This was ghc.org; Washington State). It also correctly stated that the exchange version can be purchased only directly from the exchange.
One of the things I’m finding interesting is the way so-called private exchanges are developing. By trying to create this giant risk pool that lumps all the bad risks together with those low risk patients that can be coerced into signing up, the feds have created an opportunity for employers (who collectively have a pool of individuals in relatively good health simply because they wouldn’t be working if they weren’t able to) to form their own risk pool based on that health status of that group, then go shop for coverage at rates less than the exchange policies. Essentially, they’re cherry-picking some of the good risks from the exchanges. We’ll see what the impact of that is...
