A Medicare Advantage plan, also known as Medicare Part C, is a type of Medicare health plan offered by private insurance companies that contract with Medicare to provide all your Part A and Part B benefits. Medicare Advantage plans typically offer additional benefits such as vision, hearing, and dental coverage. Unlike Original Medicare, a fee-for-service program where you can see any doctor or hospital that accepts Medicare, Medicare Advantage plans usually require you to see providers within the plan’s network. Additionally, Original Medicare does not have an out-of-pocket maximum, while the best Medicare Advantage plans have a cap on out-of-pocket expenses.
