Eligibility for Medicare based on age typically begins at 65 for U.S. citizens and permanent residents with sufficient work credits. Those already receiving Social Security benefits are automatically enrolled. Individuals under 65 may also qualify if they have a disability or specific medical conditions, such as End-Stage Renal Disease. Understanding the age-based requirements helps ensure timely enrollment and access to essential healthcare coverage.
