In Massachusetts, you can go back to Medigap later
Massachusetts law makes Medigap companies accept you from February 1 to March 31 each year. Your age and health do not change the price. Coverage from that window starts on June 1. The companies also sell Medigap during the rest of the year. So you can try Medicare Advantage and go back to Original Medicare with Medigap later.

Massachusetts sets its own Medigap plans: Core and Supplement 1A. Supplement 1 is open only to people who were eligible for Medicare before 2020. These plans are not the plans with letters, such as Plan G and Plan N. This guide has no prices for these plans, so the Original Medicare totals leave out Medigap. A plan with no drug coverage counts drugs at full price, unless its members can add a separate drug plan. A plan name with a link opens a page where you can change the care level and your drugs.
