If you've had health insurance through work most of your life, you probably take it for granted that you'll be covered whether you go to the doctor, pharmacy, dentist or eye doctor.

With Original Medicare, that's not the case. You get medical and hospital coverage from the government. You get prescription coverage from private companies. And dental and vision care isn't covered at all.

If you're looking for health insurance that's similar to what you're used to with your group coverage, a Medicare Advantage plan might be right for you.

Most Medicare Advantage plans offer medical, hospital and Part D prescription drug coverage on one card. Many of these plans also offer dental and vision coverage.

Medicare Advantage plans have an out-of-pocket maximum, which means there's a cap on how much you spend for health care each year. Plus, all your care is run through one company. You don't need to coordinate between the government and a separate Part D prescription drug plan.
