The most popular question I receive on a daily basis is " What is the Best Medicare Supplement Plan" for me or my spouse. It really boils down to three choices. Plan F, Plan G or Plan N. I will walk you through, step by step, the three most popular plans offered by Medicare today. Well, those are the top three plans nationwide, but it is important to understand how each plan will work and why one of these plans is likely to best for you. Medicare offers 11 plans nationally, but not all carriers in your market may offer one of these three or any of the other 8 plans in your particular zip code or county. Insurance carriers offer three different ways to make plans available to you depending on whether it is a statewide offering or plans are offered by zip code or on a county-wide basis.
