In the past, Medicare Supplement Plan F was the plan of choice for those seeking the fullest, most flexible coverage. In 2015, Congress passed the Medicare Access and CHIP Reauthorization Act (MACRA). This Act limits the ability of new Medicare beneficiaries to purchase plan F after January 1st, 2020. Medicare beneficiaries already with Plan F can keep that plan.
Medicare Supplement Plan F provides first dollar coverage. More specifically, Medicare Supplement Plan F pays the Medicare Part B annual deductible ($185 in 2019). This meant that when you went to the doctor, in most cases, you did not pay anything out-of-pocket. Congress wants Medicare beneficiaries to have skin in the game. Thus, they have decided to phase out Plan F for new Medicare beneficiaries.
Existing Plan F Medicare Supplements are grandfathered; you may keep your Plan F Medicare Supplement if your Medicare Entitlement date is prior to January 1st, 2020. Plan F is still a good plan, but in some areas Plan G can provide comparable coverage at a lower overall cost. The only difference between the plans is that Plan F covers the Medicare Part B deductible and Plan G does not. In 2019, the Medicare Plan B annual deductible was $185. The premium savings for Plan G generally was greater than the additional $185 benefit that Plan F provides.
