Medicare Supplement Insurance

Medicare Supplement Insurance (also called Medigap) is a type of private insurance plan that can work alongside your Original Medicare coverage to help cover some out-of-pocket Medicare costs such as copayments, coinsurance and deductibles.

You can compare different types of Medicare plans, including Medicare Supplement Insurance, to find the type of coverage that's the best fit for your needs.

How does Medicare Supplement Insurance work?

After you enroll in Original Medicare (Medicare Part A and Part B), you may incur some out-of-pocket Medicare costs when you use your coverage.

For example, you have to meet the Medicare Part B deductible ($198 in 2020) before Part B will start covering some of the costs of your care. And once it does, you are still typically responsible for a 20 percent Part B coinsurance for approved services.

A Medicare Supplement Insurance plan can help provide coverage for some of these out-of-pocket Medicare costs.

You typically pay a monthly premium to belong to a Medigap plan.

What does Medicare Supplement Insurance cost?

Medicare Supplement Insurance is sold by private insurance companies, so the cost of a plan can differ between one carrier or location and another.

There are a few other things that may affect the cost of a Medigap plan:

  • The amount of coverage offered by the plan
  • Whether or not medical underwriting is used as part of the application process
  • The age at which you join the plan
  • Eligibility for any discounts offered by the carrier
  • Gender (women often pay less for a plan than men)

Medigap eligibility

In order to be eligible for a Medicare Supplement Insurance plan, you must be at least 65 years old, enrolled in Medicare Part A and Part B and reside in the area that is serviced by the plan.

Some states – but not all – allow Medicare Supplement Insurance enrollment for Medicare beneficiaries under the age of 65.

Enrolling in a Medigap plan

Your six-month Medigap Open Enrollment Period begins when you are 65 years old and enrolled in Part A and Part B.

During your Medigap Open Enrollment Period, insurance companies are not allowed to use medical underwriting to determine your premium rates when you apply for a policy. This means that if you apply for a plan during this period, you cannot be charged more due to your age or health history.

Once your six-month open enrollment window ends, you may be subject to underwriting and may pay higher plan premiums. Insurance companies also reserve the right to deny you a policy based on the results of the underwriting. That’s why it’s highly advisable to take advantage of your Medigap open enrollment period.

Frequently asked questions about Medicare Supplement Insurance

What is the difference between Medicare Supplement and Medicare Advantage?

Medicare Supplement plans and Medicare Advantage plans work very differently, and you can't have both at the same time.

Medicare Supplement plans work alongside your Original Medicare coverage to help cover out-of-pocket Medicare costs like deductibles and coinsurance.

Medicare Advantage plans replace your Original Medicare coverage. Many plans also offer other benefits such as prescription drug coverage or dental care, which Original Medicare doesn't typically cover.

Why is Plan F popular?

Medigap Plan F covers more out-of-pocket Medicare costs than any other standardized type of Medigap plan. In exchange for their monthly premium, Plan F beneficiaries know that all of their Medicare deductibles, coinsurance, copays and other out-of-pocket costs will be covered.

For many Medicare Supplement beneficiaries, this piece of mind and ease of use are the reasons they chose to enroll in Plan F.

How are Medicare Supplement plans changing in 2020?

New Medicare beneficiaries who first became eligible for Medicare on or after January 1, 2020 will no longer be able to enroll in Medigap Plan F or Plan C.

If you already had Plan F or Plan C, you can keep your plan. If you became eligible for Medicare before Jan. 1, 2020, you can apply for Plan F or Plan C after this date if either plan is available where you live.

Also new in 2020 is high-deductible Plan G, which offers comparatively lower monthly premiums in exchange for having to meet an annual deductible before Plan G benefits kick in.
