Medicare Part C, also known as Medicare Advantage, is a private health plan option that is approved by Medicare and offered by private insurance companies that includes Part A, Part B, and usually part D.

Medicare Advantage plans are required to provide benefits at least equal to Original Medicare (Parts A & B), but they can also offer extra benefits such as vision, hearing, and dental coverage.

Medicare Advantage plans may have lower out-of-pocket costs than Original Medicare. They also include a maximum out-of-pocket, which Original Medicare does not have.
