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.

How does Medicare Supplement Insurance work?

If you have 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 ($185 in 2019) 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.
