Medicare supplement insurance is health insurance that fills gaps in Medicare coverage. Because of this, it is commonly referred to as "Medigap" insurance. It can help pay your share (coinsurance, copayments, or deductibles) of the costs of Medicare-covered services. In order to be eligible for Medicare supplement insurance, you must be enrolled in part A and part B of Medicare.
Medicare supplement insurance can also provide coverage for services that Medicare does not cover. An example is medical care when you travel outside the United States.
Medicare supplement insurance is not the same as Medicare advantage insurance. Medical supplement insurance supplements Medicare benefits while Medicare advantage insurance is a way to get Medicare benefits.
It is important to note that Medicare supplement insurance only provides coverage for one person. Spouses must have sepereate policies.
Medicare supplement insurance generally has a guaranteed renewable clause.
Medical supplement insurance, usually, does not cover long-term care, vision care, dental care, hearing aids, eyeglasses, or private-duty nursing.
