What Is Medicare?
Medicare is federal health insurance for people 65+ and some younger people with disabilities. Here's how Parts A, B, C, and D fit together — and where to start.
Medicare vs Medicaid
Medicare is age-based federal insurance; Medicaid is income-based. Some people qualify for both. Here's how they differ and what 'dual-eligible' unlocks.
Medicare Eligibility
Most people qualify for Medicare at 65; some younger people with disabilities qualify earlier. Here's exactly how to know when you're eligible and whether you can delay.

Getting-started questions
Is Medicare free?
Not entirely. Part A is usually premium-free if you or your spouse paid Medicare taxes for 10+ years. Part B has a standard monthly premium set each year, and Part D and Medicare Advantage premiums vary by plan — some Advantage plans are $0 premium, but $0 premium is not the same as free, because you still have copays and deductibles.
Is Medicare the same as Medicaid?
No. Medicare is federal health insurance based mainly on turning 65 (or disability), regardless of income. Medicaid is a joint state-federal program based on limited income and resources. Some people qualify for both and are called 'dual-eligible,' which often unlocks extra help.
When should I start learning about Medicare?
About 6 months before you turn 65. That gives you time to understand your options before your Initial Enrollment Period opens (the 7 months around your birthday) so coverage is ready the day you're eligible.
Do I need Part D if I don't take any medications?
Usually yes, to avoid a permanent late-enrollment penalty later. A low-cost Part D plan now is almost always cheaper than the penalty you'd owe for life if you sign up after going without creditable coverage.
