When you become eligible for Medicare, you reach a fork in the road. Down one path is Medicare Advantage (Part C); down the other is Original Medicare paired with a Medicare Supplement — better known as Medigap. Both are legitimate, popular choices. The trouble is that the marketing around them is loud, and the real tradeoffs are quiet. Let's fix that.
The 30-second version
- Medicare Advantage bundles your hospital, medical, and usually drug coverage into one plan from a private insurer — often with a monthly premium that varies by plan and extras like dental and vision. In exchange, you use the plan's provider network and pay copays as you go, up to a yearly out-of-pocket maximum.
- Medigap keeps you on Original Medicare and adds a policy that pays most of the costs Medicare leaves behind. You pay a higher monthly premium, but you can see any doctor in the country who accepts Medicare, with very predictable out-of-pocket costs.
How they compare, side by side
| Medicare Advantage | Original Medicare + Medigap | |
|---|---|---|
| Monthly premium | Varies by plan (plus Part B) | Higher (Medigap + Part B + Part D) |
| Doctor & hospital choice | Plan network | Any provider that accepts Medicare |
| Costs when you use care | Copays until you hit the yearly cap | Very low and predictable |
| Prescription drugs | Usually built in | Add a separate Part D plan |
| Extra benefits | Dental, vision, hearing often included | Generally not included |
| Best for | Lower monthly cost, bundled benefits | Maximum freedom & predictability |
Five questions that usually settle it
Instead of arguing which plan "wins," ask yourself these:
- How attached are you to your doctors? If you have specialists you love or you split time between states, Medigap's go-anywhere freedom is hard to beat. If your doctors are local and in-network, Advantage may serve you well.
- How do you feel about surprise bills? Medigap is built for people who would rather pay a steady premium than face a copay every time they need care. Advantage costs less month to month but asks you to pay as you go.
- Do you travel often? Original Medicare + Medigap travels with you nationwide. Advantage networks are usually regional.
- What's your monthly budget? If a higher fixed premium is tough, Advantage's low premium can be a real advantage — as long as you understand the copays.
- Are you healthy now? This is the sleeper question — see below.
The timing trap most people miss
When you first enroll at 65, you have a one-time Medigap Open Enrollment Period where you can buy any Medigap plan with guaranteed-issue rights — no health questions, no denials. Choose Advantage first and later try to switch to Medigap, and in most states you can face medical underwriting, where your health history affects whether you're approved and what you pay.
Don't forget drug coverage
If you go the Medigap route, you'll add a standalone Part D drug plan. The cheapest Part D plan isn't the one with the lowest premium — it's the one that covers your specific medications for the lowest total annual cost. We run your exact drug list through every plan so your combined cost stays as low as possible.
