Medicare is the United States' health insurance program that helps to cover the cost of healthcare for people age 65 or older. Upon turning 65, U.S. citizens can enroll in Original Medicare, consisting of Part A and Part B.
Medicare Part A is the portion of Medicare that covers inpatient care in hospitals and limited stays at skilled nursing facilities. Medicare Part A may also cover certain home health and hospice care services.
Unlike Part B, Medicare Part A is free of cost for most beneficiaries who have worked and paid taxes throughout their adult lives.
