Medicare Advantage Plans:

A Medicare Advantage Plan is a type of Medicare health plan offered by a private company contracted with Medicare to provide you with all your Part A and Part B benefits. Medicare Advantage Plans include Health Maintenance Organizations, Preferred Provider Organizations, Private Fee-for-Service Plans, Special Needs Plans, and Medicare Medical Savings Account Plans. If you're enrolled in a Medicare Advantage Plan, Medicare services are covered through the plan and are not paid for under Original Medicare. Most Medicare Advantage Plans offer prescription drug coverage.
