All seniors citizens 65 and over are entitled to Medicare, a federal health care program that covers services for seniors. The federal government divides Medicare into two different parts — Parts A and B — which cover different services. Seniors can also purchase Medicare supplemental plans (Part C).
Individuals under 65 may qualify for Medicare if:
They have been receiving Social Security Disability Insurance (SSDI) for more than two years.
They have amyotrophic lateral sclerosis (ALS).
They are currently experiencing end-stage renal disease and have paid Social Security taxes for a specific length of time.
