Medicare Insurance is a federal health insurance program primarily designed for people aged 65 or older, but it also covers certain younger individuals with disabilities or chronic conditions. Medicare helps cover hospital care (Part A), medical services and preventive care (Part B), prescription drugs (Part D), and offers additional options through Medicare Advantage (Part C).

This insurance is vital for retirees who need affordable healthcare coverage in their later years. It reduces out-of-pocket expenses, provides preventive screenings, and ensures access to essential medical services. Many seniors also choose supplemental "Medigap" policies to fill coverage gaps.
