Medicare Advantage, also known as Medicare Part C, is a type of health insurance plan that is an alternative to Original Medicare (Medicare Part A and Part B). Medicare Advantage plans are offered by private insurance companies and provide the same benefits as Original Medicare, but they often include additional benefits such as vision, hearing, and dental coverage. They may also have lower out-of-pocket costs, and may require you to see doctors within the plan’s network. Some Medicare Advantage plans also include prescription drug coverage. It is important to note that if you enroll in a Medicare Advantage plan, you give up your right to enroll in a stand-alone Medicare Part D plan for prescription drug coverage.
