Medicare, a government-funded national insurance program, has four different types.
Basic Medicare coverage is basically provided in Parts A and B. Individuals who do not qualify for Social Security benefits will automatically benefit from Medicare Parts A and B but will have to enroll themselves in Medigap and Part D.
Part A (Hospital Insurance):
Coverage for inpatient hospital stays, care, hospice care, home health care, and skilled nursing facility
Part B (Medical Insurance):
Coverage for doctor visits, ambulance services, preventive services, and some durable medical equipment.
Part C or Medicare Advantage:
Combines Part A and B benefits into a single plan offered by private insurers. It may also include prescription drug coverage (Part D).
Part D or Prescription Drug Coverage:
Offered by private insurers to help provide coverage for prescription drugs. You can get Part D as a separate plan if you have Original Medicare (Part A & B).
