You can still buy your own in the marketplace, but you would not be eligible for any subsidies unless the premiums at work exceeded a certain % of your annual income. I am not sure what that % is for 2015.

How much is it available to you for on the open market? Before or after government subsidies?

without $184 for the bronze.

If it is less than that and you decline it you're not eligible for any subsidies or tax credits.

Otherwise, no.

I always get confused about what bimonthly means.

If it's twice a month, you'll be paying what the Medicare Part B premium would be, which is interesting. And that adds up to about $1300/year, which is decidedly less than 9% of your income.

Sounds like a pretty good deal, given what some companies charge for employee health insurance. Do read the fine print on the policy. While the ACA does require that preventative things be covered, you may be shocked to learn what isn't covered. I once actually read the policy provided through a job, and it was a bit scary.
