There are 10 standardized Medicare Supplement plans available in most states. They are lettered from Plan A to Plan N, though some plans are no longer available to new beneficiaries. Regardless of the insurance company, each plan should offer the same basic benefits.
People who became eligible on January 1, 2020, or after are not able to purchase a Medigap plan that helps with Part B deductibles, such as Medicare Supplement Plan C and Plan F. However, people who already have the plans are allowed to hold the policy.
Medigap plans cover some out-of-pocket costs for Medicare Part A, such as copayments, coinsurance, and extended hospital stays. All Medicare Supplement plans also cover some Part B costs such as copayments, coinsurance, deductibles, and excess charges.
