I would start with the Massachusetts Health Care Exchange site (which is having technical problems right now), however their plans usually have in network restrictions to keep costs lower. It is my understanding that you must go through the exchange to get the federal subsidy. If the Massachusetts Exchange site doesn't pan out, I would check into Massachusetts Blue Cross Blue Shield. Make sure it's a PPO with national coverage. HMO's restrict care to network hospitals and doctors and if you go outside their network, you pay a much higher out of pocket. Another national company you could check with is United Health Care. Warning: It won't be cheap.
