How Medicare Actually Works

Medicare has four parts, dozens of plan types, and enrollment windows that can cost you money if you miss them. We break it all down — in plain English, with no agenda.

🏥

Original Medicare (Parts A & B)

Hospital insurance and medical insurance — the foundation everything else is built on. What it covers, what it doesn’t, and what you’ll pay.

Medicare Supplement (Medigap)

How the Parts Fit Together

Medicare isn’t one thing — it’s a system with four parts and two coverage paths. Here’s the 30-second version:

  • Original Medicare (Parts A + B) is your baseline — hospital and medical coverage from the government
  • Path 1: Add a Medigap supplement + standalone Part D drug plan (maximum freedom, predictable costs)
  • Path 2: Replace with Medicare Advantage (Part C) that bundles everything into one plan (lower premiums, but with networks)
  • Both paths are legitimate. Neither is universally “better.” Your health, medications, doctors, and budget determine which is right for you.

That’s what our workshop and advisors help you figure out.
