With Original Medicare, your benefits are administered by the federal government, unlike Medicare Advantage where the benefits are managed through a private insurance company. Medicare pays the Medicare Advantage carrier to administer your benefits.
Original Medicare has no network limitations. Medicare Advantage has limited doctor networks and when you need to see a specialist with a small network, access to care can be more challenging.
Most Medicare Advantage plans offer benefits beyond what Original Medicare covers like gym membership, over the counter (OTC) allowance, dental, hearing, vision, and transportation to doctor visits.
