What are the four parts of Medicare?

Part A (hospital insurance), Part B (medical insurance), Part C (Medicare Advantage), and Part D (prescription drug coverage).

Is Medigap one of the four parts of Medicare?

No. It’s a separate, private supplemental option that works alongside Original Medicare, not an official “part” of Medicare itself.

Do I need all four parts of Medicare?

Not necessarily. Most people start with Parts A and B, add Part D for prescriptions, and then choose either Medigap or Medicare Advantage—not both—to fill Original Medicare’s remaining gaps.

What’s the biggest gap Original Medicare leaves open?

Original Medicare has no annual out-of-pocket maximum. A serious illness can generate open-ended costs, which is why many people add Medigap or choose Medicare Advantage.

Can I have both Medigap and Medicare Advantage?

No. They’re mutually exclusive. Medigap supplements Original Medicare, while Medicare Advantage replaces Original Medicare as the method through which you receive Medicare-covered benefits.
