Medicare Supplement Insurance Eligibility

4 things to know about Medigap eligibility:

  1. To buy a policy, you must be enrolled in Medicare Parts A & B and be over 65.
  2. You can buy a policy outside of your Medigap open enrollment period, but your health history could affect your eligibility and premium.
  3. You cannot buy a Medigap policy if you have a Medicare Advantage Plan.
  4. If you’re under 65 and enrolled in Medicare, you may be able to buy a policy if you’re disabled.

To be eligible for Medicare Supplement insurance, you must be:

  1. Enrolled in Medicare Parts A & B (Original Medicare)
  2. 65 or older, or have a disability

You can also buy a policy if you are 65 or older, have Part A, and are enrolling in Part B.

You cannot buy a Medicare Supplement policy if you have a Medicare Advantage Plan. These two types of coverage are incompatible. If you want to switch from a Medicare Advantage Plan to a Medicare Supplement policy, you must first disenroll from the Medicare Advantage policy.

There is another thing that could affect your ability to buy coverage: Your health history.

How your health history can affect your eligibility

No matter what, it’s always best to apply for a policy during the open enrollment period. That’s because, during this period, insurers are not allowed to deny you a policy or raise your rates because of past health problems.

If you buy outside of the open enrollment period, this protection may not be there. In this situation, insurers may raise your rates or choose to not offer you a policy because of your past health problems.
