Not a single MA plan offered in my county so the choice is easy. But I do have to decide between high deductible and regular Medigap Plan.
Plus, Plan F will not be offered after 2019. Those in Plan F will be able to continue the plan for the rest of their lives, but because there will be no new enrollees after 2019, the population of that plan will be older and sicker as the years go by.
