    What does Medicare Supplement, or Medigap, mean?

    Medicare Supplement Insurance, also known as Medigap, is private health insurance that adds on to Original Medicare (Part A and B). It helps pay about 20%1 of the Medicare expenses that Original Medicare doesn't cover.

    Do you need a Medicare Supplement (Medigap) plan if you have Original Medicare?

    While Medicare covers many types of medical bills, there are still additional costs that you may be left to pay on your own. Medicare covers around 80% of health care costs. For large medical bills, this can leave customers with a lot to pay on their own.

    Medicare Supplement Insurance can help pay for some costs that Original Medicare does not cover.

    What does Medicare Supplement Insurance cover?

    Medicare Supplement Insurance helps cover some costs not paid by Original Medicare Part A and B, including:

    • Copays
    • Coinsurance
    • Deductibles

    Medigap can also help pay for additional out-of-pocket costs, such as:

    • Hospitalization
    • Doctor’s services
    • Home health care
    • Lab costs
    • Durable medical equipment

    Original Medicare will pay its share of the Medicare-approved amount for covered health costs. Then, your Medicare Supplement Insurance plan will pay its share of the costs it covers.

    There are a wide range of Medicare Supplement plans that differ in coverage and costs, from basic to extensive. Compare Cigna HealthcareSM Medicare Supplement plans

    What does Medicare Supplement Insurance not cover?

    Medicare Supplement policies do not include:

    But you can buy those plans separately. Cigna Healthcare2 offers both prescription and dental plans, many with lower cost monthly premiums.

    How does Medicare Supplement Insurance work with Original Medicare?

    To purchase a Medigap policy, you must already be enrolled in both Original Medicare Part A and Part B. Medicare Supplement Insurance provides additional coverage to your Original Medicare benefits.

    If you choose to buy a standalone Part D Prescription Drug plan, Medicare Supplement works with that, too.

    Medicare Supplement Insurance is different from Medicare Advantage. You can have either a Medicare Advantage Plan or a Medicare Supplement Plan, but not both at the same time.

    Who is eligible for Medicare Supplement Insurance?

    If you are age 65 or older and enrolled in Original Medicare Part A and Part B, you may be eligible to apply for Medicare Supplement Insurance. Medicare Supplement plans are also available to you if you’re younger than age 65 and eligible for Medicare due to disability.**

    When can you enroll in Medicare Supplement plans?

    You can apply for a Medicare Supplement plan at any time throughout the calendar year, but during your 6-month open enrollment period3, you can buy any policy offered in your state and you are guaranteed coverage even if you have pre-existing health conditions.

    • If you are retiring at 65 and applying for Medicare Part B, your open enrollment period lasts for six months starting the first day your Part B coverage begins.
    • If you are not retiring until later and still getting medical coverage under your employer’s insurance, then your open enrollment starts when you do retire and sign up for Part B coverage.

    What are the types of Medicare Supplement plans?

    There are up to 10 Medicare Supplement plans offered in each state. The different types of Medigap plans are named alphabetically, Plan A through Plan N. (Note, that they are not the same as other parts of Medicare, which are also named alphabetically.)

    The types of plans that are offered may differ depending on which state you live in, but no matter where you live, each policy is standardized and offers the same basic benefits.

    Medicare Supplement plans range from those that offer basic coverage, to those offering a much higher level of coverage. Understanding your health care needs, as well as your financial situation, can help when choosing a Medicare Supplement plan.

    How much does Medicare Supplement Insurance cost?

    When you purchase a Medigap policy, you’ll pay your insurance company a monthly premium. The cost of your Medicare Supplement premium will depend on which health insurance company you choose as well as which type of Medigap plan you select.

    However, remember that core Medicare Supplement Plan benefits are the same no matter which insurer you choose (for example, Plan G with Company A is exactly the same as Plan G with Company B). Be sure to shop and compare Medicare Supplement Insurance options to find the best fit for your budget.
