You may want to find out if you qualify for Medicaid, if your income and assets are low enough. Medicaid helps many low-income people on Medicare with their Medicare premiums and cost-sharing requirements, and may also cover some benefits that are not covered by Medicare, such as dental services and long-term services and supports.

Medicare supplement insurance policies, or Medigap policies, help to pay the copayments, coinsurance, and deductibles for Medicare-covered benefits under traditional Medicare (Part A and Part B services). Some Medigap policies also cover services that traditional Medicare does not cover, such as medical care when you travel outside the country.
