Medicare: What Are Medigap Plans?

Medigap is extra health insurance that you buy from a private company to pay health care costs not covered by Original Medicare, such as co-payments, deductibles, and health care if you travel outside the U.S. Medigap policies don't cover long-term care, such as stays in a nursing facility, or dental care, vision care, hearing aids, eyeglasses, and private-duty nursing. Most plans do not cover prescription drugs.

You pay a monthly premium for a Medigap policy. However, if you use health services not covered by Medicare, your Medigap policy may save you money in the long run. You have to decide whether paying for a Medigap policy makes sense for you.

Medigap policies are only available to people who already have Medicare Part A for hospital services and Medicare Part B for doctor services. People who have a Medicare Advantage plan cannot get a Medigap plan (and shouldn't need one.)

To learn about Medigap plans offered in your area, you can use the online Medicare Personal Plan Finder or contact your state's department of insurance.

Standard Medigap plans are labeled A through N and offer different levels of health coverage. Plans E, H, I, and J are no longer available to new subscribers.

Premiums vary among insurance companies, but the benefits of each standard Medigap plan are always the same. For instance, a Medigap Plan C policy should offer set benefits no matter which company you buy it from. However, standard Medigap policies are different in Massachusetts, Minnesota, and Wisconsin.

If you are going to buy a Medigap plan, the open enrollment period is six months from the first day of the month of your 65th birthday -- as long as you are also signed up for Medicare Part B -- or within six months of signing up for Medicare Part B. During this time, you can buy any Medigap policy at the same price a person in good health pays. If you try to buy a Medigap policy after six months, there is no guarantee that you'll be able to get coverage. If you do get covered, your rates might be higher. 

For a Medigap plan, you pay a monthly premium to the insurance company in addition to your Medicare Part B premium. The cost of your Medigap policy depends on the type of plan you buy, the insurance company, your location, and your age. A standardized Medigap policy is guaranteed renewable -- even if you have health problems -- if you pay your premiums on time.

However, you may have to wait up to six months for coverage if you have a pre-existing health condition. The insurer through which you buy your Medigap policy can refuse to cover out-of-pocket costs during that period. After six months, the Medigap policy will cover the pre-existing condition. The exception to this rule is if you buy a Medigap policy during your open enrollment period and have had continuous "creditable coverage," or a health insurance policy for the six months before buying a policy. The Medigap insurance company cannot withhold coverage for a pre-existing condition in that case.
