What is Original Medicare?
The key point: Original Medicare covers a lot, but it doesn’t cover everything. You’ll still face copayments, coinsurance, and deductibles, which can add up.
A Medigap plan, also called Medicare Supplement Insurance, helps fill the gaps left by Original Medicare.
Example: If you’re admitted to a hospital, Original Medicare covers most of your stay under Part A, but you might still owe coinsurance. Medigap can pay that coinsurance for you, reducing unexpected bills.
Original Medicare does not include prescription drugs, which is where Part D comes in:
Example: If your doctor prescribes a brand-name medication, Part D can significantly lower your out-of-pocket costs.
Here’s the flow:
Benefit: You get broad, predictable coverage and protection against high medical costs.
Important Note: You cannot use a Medigap plan with Medicare Advantage (Part C) — Medigap only works with Original Medicare.
Original Medicare + Medigap + Part D is often ideal if:
Considerations: You’ll have multiple premiums (Part B, Medigap, Part D), so budgeting is important.
Combining Original Medicare with Medigap and Part D gives you a solid, flexible healthcare safety net. It’s the classic route for people who want broad coverage, financial protection from high medical costs, and freedom to choose their providers.
Tip: Compare Medigap plans carefully — premiums and coverage can vary by state and insurer, but all plans offer standardized benefits. And always review Part D formularies to ensure your medications are covered.
