What Is a Medicare Supplement Plan?

Also known as Medigap, a Medicare Supplement plan helps pay the out-of-pocket costs that Original Medicare doesn’t cover—like deductibles, copays, and coinsurance. These plans are offered by private insurance companies and work alongside your Original Medicare coverage.


If you want predictable costs and freedom to see any doctor who accepts Medicare, a Supplement plan may be the right fit.

Why Choose a Medigap Plan?

With this plan, you get:
  • More financial predictability with fewer surprise bills.

  • Freedom of choice to visit any provider nationwide that accepts Medicare.

  • No referrals required to see specialists.

  • Coverage that travels with you anywhere in the U.S.

FAQs

  • What’s the difference between a Supplement plan and a Medicare Advantage plan?

    Supplement (Medigap) plans work with Original Medicare to help pay out-of-pocket costs. Medicare Advantage plans replace Original Medicare with bundled private coverage. We’ll help you decide which is best for you.

  • Do Supplement plans cover prescriptions?

    No, you’ll need a separate Part D prescription drug plan. We can help you choose both together.

  • When can I enroll in a Medigap plan?

    The best time is during your 6-month Medigap Open Enrollment Period when you first enroll in Part B. In Missouri, you may also switch plans each year during your Medigap anniversary window.
