Medicare does not cover all healthcare expenses. For example, if you stay in the hospital or a skilled nursing facility for an extended period of time, those costs may not be covered by your Medicare plan. In addition, there are other costs and medical expenses Medicare does not cover. This is where Medicare Supplement insurance, or Medigap, can be a good option.

What is Medicare Supplement Insurance (Medigap)

Medicare Supplement insurance (Medigap) is provided by private insurance companies to pay for healthcare costs that Medicare does not cover.

What Medicare Supplement Insurance Provides

These plans help cover costs that are not covered by Medicare, including:

  • Deductibles
  • Copayments
  • Coinsurance
  • Care received while traveling outside the U.S.

Medicare Supplement Insurance Eligibility

For you to be eligible for Medicare Supplement insurance, you must:

  • Be a permanent resident of and reside in the plan’s state for at least six months of each calendar year
  • Be age 65 or older
  • Be enrolled in both Medicare Part A and Part B
  • Continue to pay your Part B premium

How Do I Enroll?

You can enroll in Medicare Supplement insurance offered by any private insurance company in your state. You can apply directly with the insurance company or through your insurance agent. If you are eligible to purchase Medicare supplement insurance, there is a 6-month enrollment period that begins when you are 65 years old and enrolled in Medicare Parts A and B. Once enrolled, the policy is guaranteed renewable. So, as long as you pay your premium, it is automatically renewed each year, regardless of your health status.

If you apply after the open enrollment period has ended, an insurance company is allowed to use medical underwriting to approve coverage and to determine the price of the policy. So there is a possibility you will be denied coverage or offered only limited coverage.
