Medicare has four parts: Part A, B, C and D and one additional type of plan called Medicare Supplement (Medigap). Part C, also known as Medicare Advantage plans are provided through private insurance companies, but contracted with and approved by Medicare. They are required to offer at least all of the same benefits provided by Medicare Parts A & B and can provide additional coverage for prescription drugs, dental vision, hearing and gym memberships. It is important to note that not all Medicare Advantage plans offer the same benefits and not all are available in every state and county. There is competition between the carrier’s plans that are offered and consequently you can seek plans to meet your unique needs.
