Important: If you have a Medigap policy and you are switching from Original Medicare to a Medicare Advantage Plan, you don’t need and can’t use the Medigap policy to cover deductibles, copayments, or coinsurance under the Medicare Advantage Plan. You may choose to drop your Medigap policy, but you should talk to your State Health Insurance Assistance Program (see pages 49–50) and your current Medigap insurance company before you do because you may not be able to get it back. If you already have a Medicare Advantage Plan, it is illegal for anyone to sell you a Medigap policy unless you are switching back to Original Medicare.
