Medicare Advantage is a Medicare-approved plan from a private company that offers an alternative to Original Medicare for your health and drug coverage. These “bundled” plans include Part A, Part B, and usually Part D. In most cases, you can only use doctors who are in the plan's network.

Medicare Advantage Plans, sometimes called “Part C” or “MA Plans,” are offered by private companies approved by Medicare. If you join a Medicare Advantage Plan, the plan will provide all of your Part A (Hospital Insurance) and Part B (Medical Insurance) coverage.

Many Medicare Advantage plans include prescription drug coverage. This means you don't have to purchase a separate Part D plan and pay a separate premium. With MA, you can enjoy the ease and convenience of having your hospital, medical, and prescription drug coverage rolled up into a single plan.
