Medicare is a federal health insurance program for people 65 and older, certain younger individuals with disabilities, and those with specific medical conditions. Eligibility generally begins at age 65.
Original Medicare includes Part A (hospital) and Part B (medical) coverage. Medicare Advantage (Part C) is offered by private companies and combines Parts A, B, and usually Part D (prescription drugs), often with extra benefits like dental or vision.
Medigap, or Medicare Supplement insurance, helps cover costs not included in Original Medicare, such as copays, coinsurance, and deductibles. It’s optional but can provide predictable out-of-pocket expenses and nationwide coverage.
