Medicare Advantage, also known as Medicare Part C, is an alternative to Original Medicare (Parts A and B) offered by private insurance companies approved by Medicare. Medicare Advantage plans combine the benefits of Part A and Part B, and often include additional coverage such as prescription drugs (Part D), dental, vision, and wellness programs. These plans usually have network restrictions, requiring enrollees to use specific healthcare providers to get full benefits. Medicare Advantage typically requires enrollees to pay a monthly premium in addition to the Part B premium. Medicare Advantage plans vary widely, so beneficiaries can choose a plan that best suits their healthcare needs, budget, and provider preferences.
