Medicare Advantage vs Medicare Supplement: Which Is Right for You in 2026?
Medicare Advantage vs Medicare Supplement: Which Is Right for You in 2026?
By Rod Cummings, RSSA® | Legacy Wealth Services | Happy Valley, Oregon
You’re turning 65. Medicare is kicking in. And suddenly you’re staring at a stack of mail — or a screen full of tabs — trying to decode the difference between Medicare Advantage and Medicare Supplement (Medigap). Both promise to help with your healthcare costs. Both are sold by legitimate insurance companies. But they work in fundamentally different ways, and choosing the wrong one could cost you thousands of dollars or lock you out of your preferred doctors.
Here’s the good news: you don’t have to figure this out alone. As an independent Medicare specialist serving Oregonians, I’ve helped hundreds of families navigate this exact decision — and I’m going to lay it out clearly so you can walk away with real clarity.
Let’s break it all down for 2026.
What Is Original Medicare — and Why Do You Need More?
Before comparing your options, it helps to understand what Original Medicare (Parts A & B) actually covers — and what it leaves exposed.
Medicare Part A covers hospital stays, skilled nursing facility care, and some home health services. Medicare Part B covers outpatient care, doctor visits, preventive services, and medical equipment. In 2026, the standard Part B premium is $202.90/month, with a $240 annual deductible.
Here’s the problem: Original Medicare alone has no annual out-of-pocket maximum. If you have a serious illness or hospitalization, your costs can spiral — with 20% coinsurance on all Part B services adding up fast. That’s where Medicare Supplement and Medicare Advantage plans come in.
Medicare Supplement (Medigap): The “Fill the Gaps” Approach
A Medicare Supplement plan — commonly called Medigap — works alongside Original Medicare. You keep your Medicare coverage, and your Medigap plan picks up costs that Medicare doesn’t pay: deductibles, copayments, and coinsurance.
Plan G is the most popular Medigap plan for new enrollees in 2026. It covers virtually everything except the Part B deductible ($240/year). In exchange, you pay a monthly premium.
2026 Average Medigap Premiums (Age 65, National Average):
- Plan G: ~$165.85/month
- Plan N: ~$122.98/month
- High-Deductible Plan G: ~$45–65/month (you pay the first $2,950 in costs)
Note: Oregon premiums may vary by carrier and zip code. Rod can pull live quotes specific to your area.
The key benefit: With Plan G, your healthcare costs become highly predictable. You pay your monthly premium plus the $240 Part B deductible — and that’s essentially it. No surprise bills, no network restrictions, no referrals needed.
Medicare Advantage (Part C): The “All-in-One” Alternative
Medicare Advantage plans are offered by private insurance companies approved by Medicare. Instead of using Original Medicare directly, you receive your Medicare benefits through the plan. Most plans bundle in Part D drug coverage, and many include extras like dental, vision, and hearing benefits.
2026 Medicare Advantage Key Stats:
- Average monthly premium: $0–$30/month (plus your required Part B premium of $202.90)
- Median in-network out-of-pocket maximum: $5,900/year
- Maximum allowed out-of-pocket limit: $9,350/year (up from $9,250 in 2025)
- Most plans use HMO or PPO networks — your doctors must be in-network
The appeal is clear: low or no monthly premium, extra benefits, and an annual cap on costs. But the tradeoff is that you’re trading flexibility for those savings.
Side-by-Side Comparison: Medicare Advantage vs Medicare Supplement 2026
| Feature | Medicare Supplement (Plan G) | Medicare Advantage (Part C) |
|---|---|---|
| Monthly Premium | ~$165.85/mo (avg, age 65) | $0–$30/mo (+ $202.90 Part B) |
| Annual Out-of-Pocket Max | Effectively ~$240 (Part B deductible only) | Up to $9,350 in-network (2026) |
| Doctor/Hospital Choice | Any provider accepting Medicare — nationwide | Restricted to in-network providers (HMO/PPO) |
| Referrals Required | No — see any specialist directly | Often yes (HMO plans) |
| Prescription Drug Coverage | Requires separate Part D plan | Usually included (MAPD) |
| Extra Benefits (Dental/Vision/Hearing) | Not included | Often included |
| Predictability of Costs | Very high — costs are capped and consistent | Moderate — low premium, but variable cost-sharing |
| Travel/Nationwide Coverage | Full coverage anywhere Medicare is accepted | Limited to plan service area (emergency only) |
| Medical Underwriting (in most states) | Yes — health questions may apply after OEP | No — guaranteed issue year-round |
| Oregon Enrollment Flexibility | ✅ Year-round enrollment (see below) | Year-round with qualifying events |
Oregon’s Unique Advantage: Year-Round Medigap Enrollment
Most states only allow you to enroll in a Medigap plan without medical underwriting during your 6-month Medigap Open Enrollment Period — the window that begins when you turn 65 and enroll in Part B. Miss that window in most states, and insurers can charge you more or deny coverage based on your health history.
Oregon is different.
Under Oregon state law, residents have continuous open enrollment rights for Medigap plans. This means that as an Oregonian, you can apply for a Medicare Supplement plan at any time of year with guaranteed issue protections that go beyond federal law. Oregon’s SHIBA (Senior Health Insurance Benefits Assistance) program confirms these robust consumer protections in their 2026 Oregon Guide to Medicare Insurance Plans.
What this means for you: If you tried a Medicare Advantage plan and it isn’t working — wrong network, unexpected costs, moving out of the service area — you have more flexibility to switch to a Medigap plan than residents in most other states. This is a significant advantage that many Oregonians don’t know about.
The Real Cost Comparison: Two Scenarios
Numbers tell the story better than anything. Let’s look at two hypothetical Oregonians, both age 65.
Scenario A: Relatively Healthy Year
| Medicare Supplement (Plan G) | Medicare Advantage | |
|---|---|---|
| Monthly Premium | $165.85 | $0 |
| Part B Premium | $202.90 | $202.90 |
| Annual Out-of-Pocket | $240 (Part B deductible) | $500–$1,500 (copays/coinsurance) |
| Estimated Annual Total | ~$4,538 | ~$2,735–$3,735 |
Medicare Advantage wins in a low-utilization year.
Scenario B: Major Health Event (Surgery + Recovery)
| Medicare Supplement (Plan G) | Medicare Advantage | |
|---|---|---|
| Monthly Premium | $165.85 | $0 |
| Part B Premium | $202.90 | $202.90 |
| Annual Out-of-Pocket | $240 (Part B deductible) | $5,900–$9,350 (hitting OOP max) |
| Estimated Annual Total | ~$4,538 | ~$8,335–$11,785 |
Medicare Supplement wins — often by thousands — when serious care is needed.
The takeaway: Medicare Advantage can save you money in healthy years. Medicare Supplement protects you financially when it matters most. The right choice depends on your health, risk tolerance, and financial situation.
Which Plan Is Right for You? A 5-Question Framework
Work through these questions honestly:
1. How often do you use healthcare? If you rarely see doctors beyond annual checkups, Medicare Advantage’s low premiums may make sense. If you have ongoing conditions requiring regular specialist visits, Medigap’s predictability is worth the premium.
2. Do you travel frequently or spend time in multiple states? Medicare Supplement plans work with any Medicare-accepting provider in the country — no network restrictions. If you snowbird in Arizona or travel extensively, this matters enormously. Medicare Advantage plans typically only cover out-of-area emergencies.
3. Do you have preferred doctors or specialists you want to keep? Medigap lets you see any doctor who accepts Medicare — period. Medicare Advantage requires you to verify your doctors are in-network every year (networks change annually).
4. How would a $5,000–$9,000 unexpected medical bill affect you? If a large out-of-pocket expense would cause real financial stress, the predictability of a Medigap plan may be worth the higher monthly premium.
5. Do you want extra benefits like dental, vision, and hearing? Medicare Advantage plans frequently include these extras. With Medigap, you’d need to purchase standalone dental and vision coverage — though these are often available at low cost.
The Bottom Line: There Is No Universal “Best” Plan
The honest answer is that both plan types serve real needs — and the right choice is deeply personal. What works for your neighbor may be the wrong fit for you.
What I can tell you is this: the decision you make at 65 has long-term consequences. Switching from Medicare Advantage back to Medigap later in life can be difficult (though in Oregon, you have more flexibility than most). Choosing a plan based only on the lowest monthly premium can leave you exposed when you need care most.
This is why working with an independent Medicare specialist — rather than calling a 1-800 number or buying online — makes such a difference. An independent broker represents multiple carriers and has no incentive to steer you toward any particular plan. Their job is to find what’s right for you.

Frequently Asked Questions
Can I have both Medicare Advantage and Medicare Supplement? No. You cannot use a Medigap plan alongside Medicare Advantage. Medigap is designed to supplement Original Medicare (Parts A & B) only.
When is the best time to enroll in a Medicare Supplement plan in Oregon? The ideal time is during your 6-month Medigap Open Enrollment Period when you first enroll in Part B at 65 — this guarantees acceptance regardless of health. However, Oregon’s continuous open enrollment protections give you more flexibility than most states to enroll or switch later.
Will my Medicare Advantage plan cover me if I travel out of state? Most Medicare Advantage plans only cover out-of-area care in emergencies. For routine care while traveling, you would typically need to pay out-of-pocket or wait until you return to your plan’s service area.
Can Medicare Advantage plans change their benefits year to year? Yes — and this is important. Medicare Advantage plans can change their premiums, cost-sharing, networks, and covered drugs every January 1. Always review your Annual Notice of Change (ANOC) each fall during the Annual Enrollment Period (Oct. 15 – Dec. 7).
