Medicare Advantage and Medigap both fill the gaps that Original Medicare leaves behind — but they go about it in nearly opposite ways. Neither one is “better.” The right choice depends on your doctors, your travel, your budget, and your health.
The starting point is the same
Before we compare, one thing is true no matter which path you pick: you still pay the Part B premium of $202.90 a month in 2026. Both options sit on top of Original Medicare, not instead of it. From there, the two roads split.
Medicare Advantage (Part C) is an all-in-one plan from a private insurer that bundles your coverage together. Medigap (also called Medicare Supplement) is a policy that pairs with Original Medicare to pay down its gaps, and you add a separate drug plan alongside it.
Side-by-side
| Medicare Advantage | Medigap (Supplement) | |
|---|---|---|
| Monthly premium | Often $0 or low | Higher, but fixed |
| Doctors & hospitals | Network (HMO or PPO) | Any provider that takes Medicare |
| Travel coverage | Best near home | Nationwide |
| Drug coverage | Usually built in | Add a standalone Part D plan |
| Dental, vision, hearing | Often included | Not included |
| Out-of-pocket protection | Annual maximum | Predictable, very low costs |
| How costs work | Copays as you use care | Pay premium, little else |
| Stability | Plan can change yearly | Coverage stays steady |
Where Medicare Advantage shines
Medicare Advantage is appealing if you like the idea of one card and a low premium. Many plans cost $0 a month on top of your Part B premium, and they usually fold in Part D drug coverage plus extras like dental, vision, and hearing that Original Medicare doesn’t touch.
Every Medicare Advantage plan also has an annual out-of-pocket maximum — a ceiling on what you’ll spend in a year for covered medical care. That’s real protection Original Medicare alone doesn’t offer.
The trade-offs are networks and change. Most plans are HMOs or PPOs, so you generally stay with in-network doctors and hospitals, and you may need referrals or prior approval for some services. Plans are also rebuilt each year — premiums, copays, drug lists, and networks can all shift, so it pays to review your plan every fall. If you travel a lot or split time between states, a network built around home can feel tight.
Where Medigap shines
Medigap trades a higher monthly premium for predictable costs and freedom of choice. There are no networks: you can see any doctor or hospital in the country that accepts Medicare, which suits frequent travelers and snowbirds well. Once you’ve paid your premium, most of what Original Medicare would have billed you simply gets covered.
The two most popular standardized plans are:
- Plan G — covers nearly all the gaps after you pay the $283 Part B deductible for the year. After that, your covered costs are largely handled.
- Plan N — a lower premium than G; you pay the Part B deductible plus small copays (up to $20 for office visits and $50 for the ER), and any “excess charges” if a provider doesn’t accept Medicare’s rate.
Remember that Medigap doesn’t include drugs, so you’ll add a standalone Part D plan to cover prescriptions. The upside is steadiness: your coverage doesn’t get redrawn every January, and your year-to-year costs are easy to plan around.
So which one fits you?
It really comes down to a few honest questions:
- Your doctors: Are the specialists you trust in a plan’s network, or do you want the freedom to see anyone?
- Travel: Do you spend long stretches out of state?
- Budget style: Would you rather pay less each month and more as you go (Advantage), or more each month for very few surprises (Medigap)?
- Health: Do you expect a lot of care this year, or are you mostly healthy?
There’s no universal winner here — there’s only the plan that matches your life. If you’d like to see which direction leans your way, the Medicare Plan Quiz walks you through it in a few minutes, and the Cost Estimator helps you compare what each path might actually run for your situation.
One more thing worth saying: your first choice carries weight. When you’re new to Medicare, you have a one-time window to buy Medigap without health questions. Switch later and an insurer can often look at your health first. That’s not a reason to rush — it’s a reason to think it through before you decide.
