Insurance companies must offer the same standardized benefits for each plan option. This means Medigap plan types with the same letter provide the exact same basic benefits, no matter which company you buy from. Plans with different letters provide different benefits.
For example, one insurer's Plan C will have the exact same benefits as another insurer's Plan C. The only difference is price.
There are 9 different standardized benefits that Medigap policies can cover — 4 basic benefits that each plan must cover, plus 5 additional benefits. Each plan has a different combination.
It's important to note that Massachusetts, Minnesota, and Wisconsin have different types of plan options.
You can use the 2026 Medigap plan chart below to compare the benefits that are offered by each type of plan. Use the scroll bar at the bottom of the chart to view all plans and information. You can also read our list of medicare supplement plans for additional information.

Plan G is by far the most popular. 43% of all Medigap beneficiaries are enrolled in Plan G.2
The next most popular plan is Plan F. 33% of all Medigap beneficiaries are enrolled in Plan F.
Plan F is the only Medicare Supplement insurance plan that includes coverage for all 9 Medigap benefits. Plan F and Plan C, another plan that includes most Medigap benefits, are no longer available to new Medicare beneficiaries who first became eligible for Medicare on or after Jan. 1, 2020.
If you had Plan C or Plan F before 2020, you can keep your plan. And if you became eligible for Medicare before 2020, you may still be able to apply for Plan F or Plan C if they're available where you live.

Medicare Supplement Insurance plans are not the same thing as Medicare Advantage (Medicare Part C) plans. You cannot have a Medicare Advantage plan and Medicare Supplement Insurance at the same time.
Most Medicare Advantage plans also provide prescription drug coverage, which Original Medicare typically doesn't cover.
Some Medicare Advantage plans may also include coverage for services like:
Medigap plans do not provide prescription drug coverage. If you have Medicare Supplement Insurance and want to get Medicare prescription drug coverage, you can consider purchasing a Medicare Part D prescription drug plan.
