What is Medicare Insurance?
Medicare is a government health insurance programme that is available to anyone 65 years of age or older, as well as some relatively young individuals with disabilities and those who have End-Stage Renal Disease (permanent kidney failure requiring dialysis or a heart transplant, sometimes called ESRD).
Eligibility:
Most U.S. citizens and legal residents who have earned their entitlement to Medicare by working and paying taxes for a specific period of time are eligible for it.
