Most people who are eligible for Medicare start receiving benefits at age 65, according to AARP. Some individuals, such as those who have been on disability for a length of time or have some specific medical issues, are eligible at a younger age.
Lou Gehrig's disease and kidney failure are two medical problems that make individuals eligible for Medicare before the age of 65, WebMD explains. Not all who are 65 are eligible. People must have paid relevant taxes for a period of 10 years and be a citizen or legal permanent resident in addition to being 65 years old to receive traditional Medicare.
