As of January 1, 2020, Medicare Supplement plans that cover the Part B deductible are not allowed to be sold to those newly eligible for Medicare. As a result, Medicare Supplement Plans C and F are no longer available to those newly eligible for Medicare beginning January 1, 2020. If you are already enrolled in either of these two plans (or the high deductible version of Plan F), you’ll be able to keep your plan. If you were eligible for Medicare before January 1, 2020, but not yet enrolled, you may be able to buy one of these plans. Even if you are eligible to enroll in a Plan F, It is essential to talk to your independent agent first as there are a few cost concerns to consider.
