Who is eligible for Medicare?

Medicare is a federal health insurance program that primarily provides coverage for individuals who are 65 years old or older. However, it also covers certain people with disabilities who are under 65, specifically those who have been receiving disability benefits from Social Security or the Railroad Retirement Board for at least 24 months. Additionally, individuals of any age with end-stage renal disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS, also known as Lou Gehrig's disease) are eligible for Medicare. Medicare has three main parts - Part A (hospital insurance), Part B (medical insurance), and Part D (prescription drug coverage), and beneficiaries can enroll during specific enrollment periods. Understanding one's eligibility and enrollment options is crucial to access the benefits provided by the Medicare program.
