to qualify for a tax credit you must buy a health plan through the marketplace. if you are unable to find a plan that your doctor participates with you might consider choosing a ppo policy which allows you to get some coverage for doctors who are outside the plan's network.
i live in mi and my doctor is in oh. will i be able to keep my doctor if i buy a health insurance marketplace plan? . what happens if my doctor doesn't participate in the program listed? if i decide to buy a policy not on the marketplace will i still qualify for tax credits?
