At what age is a person generally eligible for Medicare?

Individuals are generally eligible for Medicare when they reach the age of 65. This age is established based on the eligibility criteria set forth by the Centers for Medicare & Medicaid Services (CMS). At 65, individuals can enroll in Medicare Part A (hospital insurance) and Part B (medical insurance), as well as potentially Part C (Medicare Advantage) and Part D (prescription drug coverage).

Enrollment can begin three months before the individual turns 65 and continues for three months after their birthday month, providing a full seven-month window to sign up. This age has been standard since the program's inception in 1965 and reflects a transition point in health care needs, as many people begin to experience age-related health issues around this time.
