Original Medicare includes Hospital Insurance (Part A) and Medical Insurance (Part B). You pay for services as you get them. When you get services, you’ll pay a deductible at the start of each year, and you usually pay 20% of the cost of the Medicare-approved service, called coinsurance. If you want drug coverage, you can add a separate drug plan (Part D).

Medicare Advantage is 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. Plans may offer some extra benefits that Original Medicare doesn’t cover — like vision, hearing, and dental services.
