First, a Medicare Supplement or Medigap plan is not a Medicare Advantage plan. Medicare Advantage plans provide a way to get all of your Medicare benefits (plus other things Medicare doesn’t cover). A Medigap plan supplements your Original Medicare benefits but doesn’t replace them with a different kind of coverage.
The purpose of a Medigap plan is to help pay for out-of-pocket costs which Original Medicare doesn’t cover…things like co-payments, coinsurance and deductibles.
Medicare Supplement plans allow you to see any doctor who accepts Medicare assignment. This means they agree to accept direct payment from Medicare and will not bill you more than the Medicare deductible and coinsurance.
Medicare Supplement plans may also offer a Select plan, which offers additional cost savings. These plans will require you to use a provider network.
The advantages of Medigap plans include:
Eight different Medigap plans are available (A, B, D, G, K, L, M and N) as of January 1, 2020. These plans are mostly standardized across the United States.
