Medicare Supplement Insurance Plans

A Medicare Supplement Insurance Plan works with Original Medicare. While Medicare Parts A and B cover a lot of health care costs, they don’t cover all costs. A Medicare Supplement Insurance Plan covers the costs that Original Medicare doesn’t, like:

                            ✔  Coinsurance                             ✔  Copayments                             ✔  Deductibles

Medicare can change these amounts each year, but Medicare Supplement Insurance Plans adjust to always cover them.

Plans are identified by the letters A, B, C, D, F, G, K, L, M and N. Each plan covers a different set of costs. Some plans only cover basic benefits. Other plans cover a wider range of health care costs and benefits.

Medicare Supplement Insurance Plans do not cover hearing, dental or vision care, or prescription drugs. However, prescription drug plans are available. Some Medicare Supplement Insurance Plans cover foreign travel care.

These plans have the same benefits for everyone. Plan G from one company has the same coverage as Plan G from another company. The only differences are premiums and service. You can use any doctor, specialist or hospital that accepts Medicare.

You can enroll in a Medicare Supplement Insurance Plan year-round, but only during the open enrollment period is acceptance guaranteed. This period starts the first month that you are 65 and enrolled in Medicare Part B. After the open enrollment period, you’ll need to meet certain requirements to be accepted and may have to pay more once you’re a member.

Important Things to Remember

You can’t have a Medicare Supplement Insurance Plan and a Medicare Advantage Plan at the same time.

Medicare Advantage Plans are health insurance plans approved by Medicare and offered by private companies. Medicare Advantage Plans are different from Medicare Supplement Insurance Plans. If you enroll in a Medicare Advantage Plan, you cannot purchase a Medicare Supplement Insurance Plan.
