Medicare can be a valuable source of health insurance coverage for seniors and those with certain disabilities or illnesses. However, it's important to review the coverage and costs of each plan to determine which plan is best for your individual needs.

To be eligible for Medicare, you must be a U.S. citizen or permanent legal resident who has lived in the country for at least five years. You are automatically enrolled in Medicare Part A and Part B if you are receiving Social Security benefits when you turn 65. If you are not receiving Social Security benefits, you will need to enroll in Medicare during your initial enrollment period.
