Medicare is a federal health insurance program primarily for people aged 65 and older, as well as certain younger individuals with disabilities. Eligibility typically depends on age, disability status, or specific medical conditions.

Initial enrollment typically begins three months before your 65th birthday and ends three months after the month of your 65th birthday. There are also special enrollment periods for certain circumstances.

Medicare has four main parts: Part A (hospital insurance), Part B (medical insurance), Part C (Medicare Advantage), and Part D (prescription drug coverage).

Medicare Advantage plans offer comprehensive coverage through private insurance companies, while Medicare Supplement plans help fill the gaps in Original Medicare coverage.
