Medicare is a national health insurance program in the United States. It began in 1965 under the Social Security Administration (SSA) by Lyndon B. Johnson and now administered by the Centers for Medicare and Medicaid Services (CMS). It gives health care insurance for Americans aged 65 and older, people with End-Stage Renal Disease and also for some younger people with disability.[1][2] Medicare consists of three parts:
Medicare Part A (Hospital Insurance): Covers inpatient hospital care, skilled nursing facility care, hospice, and some home health care.
Medicare Part B (Medical Insurance): Covers doctor office visits and services, outpatient care, medical supplies, and preventative care and services.
Medicare Part D (prescription drug coverage): Covers the cost of prescription drugs, flu shots, and vaccines.
