Medicare Advantage (also called "Part C") and Medicare Cost plans are ways to get a single combined plan including Parts A, B, and D through a private company. With Medicare Advantage plans, you may have less flexibility, but your costs could be lower. With Medicare Cost plans, you have more flexibility, because you can still use Original Medicare to pay for out-of-network providers.
As an alternative to obtaining Original Medicare coverage directly from the government, you may want to consider Medicare Advantage (sometimes referred to as Medicare Part C) in Minnesota.
