What is a Medicare Supplement (Medigap) Policy?

A Medicare Supplement Insurance (Medigap) policy, sold by private companies, can help pay some of the health care costs that Original Medicare doesn’t cover, like copayments, coinsurance, and deductibles.

8 Things to know about Medigap policies

1. You must have Medicare Part A and Part B.
2. If you have a Medicare Advantage Plan, you can apply for a Medigap policy, but make sure you can leave the plan before your Medigap policy begins.
3. You pay the private insurance company a monthly premium for your Medigap policy in addition to the monthly Part B premium that you pay to Medicare.
4. A Medigap policy only covers one person. If you and your spouse both want coverage, you’ll each have to buy separate policies.
5. You can buy a Medigap policy from any insurance company that’s licensed in your state to sell one.
6. Any standardized Medigap policy is guaranteed renewable even if you have health problems. This means the insurance company can’t cancel your policy as long as you pay the premium.
7. Some Medigap policies sold in the past cover prescription drugs, but Medigap policies sold after January 1, 2006 aren’t allowed to include prescription drug coverage. If you want prescription drug coverage, you can join a Medicare Prescription Drug Plan (Part D).
8. It’s illegal for anyone to sell you a Medigap policy if you have a Medicare Medical Savings Account.

Medigap policies don’t cover everything

Medigap policies generally don’t cover long-term care, vision or dental care, hearing aids, eyeglasses, or private-duty nursing.
