Medigap plans help cover some of the out-of-pocket expenses that Original Medicare (Part A and Part B) doesn't cover.
These costs can include things like Medicare deductibles, coinsurance, copayments and more.
A Medicare Supplement Insurance plan fills in some of the gaps left by Original Medicare, hence the nickname “Medigap.”
Insurance companies must offer the same standardized benefits for each plan option.
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.
Plan F is the only Medigap plan that covers all 9 benefits. Plan A, on the other hand, covers only the 4 basic benefits.

The average Medigap plan premium in 2023 was $130.58 per month.1
The average cost of a Medicare Supplement Insurance plan can vary based on your age, gender, smoking status, health and where you live, as well as the benefits that are offered by the plan.

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.
