Medicare Advantage vs. Medicare Supplement: Which Is Right for You?
Medicare Advantage vs. Medicare Supplement: Which Is Right for You?
If you’re approaching 65 — or helping a parent navigate Medicare for the first time — you’ve likely encountered the same overwhelming question: Should I choose Medicare Advantage or a Medicare Supplement plan?
It’s one of the most important financial decisions you’ll make in retirement, and unfortunately, one of the most misunderstood. I’ve helped hundreds of clients in Oregon and across the country work through this exact choice, and the honest answer is: there is no universally “better” option. There’s only the option that’s right for you, based on your health, your finances, and how you use healthcare.
Let me break it down clearly.
What Is Original Medicare — And Why Does It Matter?
Before comparing the two paths, it helps to understand what you’re working with.
Original Medicare (Parts A and B) is the federal program that covers hospital care (Part A) and outpatient/doctor services (Part B). In 2026, Part B costs $202.90/month in standard premiums, and you’re responsible for a $257 annual deductible plus 20% of most outpatient costs — with no cap on what you can owe in a given year.
That unlimited exposure is exactly why most people add either a Medicare Advantage plan or a Medicare Supplement policy on top of Original Medicare.
Medicare Advantage (Part C): The All-in-One Option
Medicare Advantage plans are offered by private insurance companies — think Aetna, Humana, UnitedHealthcare, Cigna, and Anthem/BCBS — that contract with Medicare to deliver your benefits.
Instead of using Original Medicare directly, your coverage runs entirely through the private plan.
What You Get With Medicare Advantage
- Low or $0 monthly premiums — many plans in Oregon cost $0/month beyond your Part B premium
- Built-in prescription drug coverage (Part D) in most plans
- Extra benefits Original Medicare doesn’t cover: dental, vision, hearing, fitness memberships (like SilverSneakers), and sometimes over-the-counter allowances
- An annual out-of-pocket maximum — in 2026, the cap is $9,250 for in-network services, after which the plan pays 100%
The Trade-Offs
- Network restrictions: Most MA plans are HMOs or PPOs. You may need referrals to see specialists, and out-of-network care can be costly or uncovered entirely.
- Prior authorization requirements: Certain procedures, tests, or specialist visits may require advance approval from the plan.
- Benefits can change annually: What the plan covers, costs, and which providers are in-network can shift every January 1st.
- Geographic limitations: If you travel frequently or spend time in multiple states, network restrictions can become a real problem.
Medicare Advantage is often a good fit for: Healthier individuals who want to minimize monthly premiums, don’t mind a managed-care network, and value the extra benefits like dental and vision.
Medicare Supplement (Medigap): The Predictability Option
Medicare Supplement plans — often called “Medigap” — work differently. You keep Original Medicare as your primary coverage, and the Medigap policy pays some or all of the gaps: deductibles, copays, and that unlimited 20% coinsurance exposure.
The Most Popular Plans in 2026
| Plan | What It Covers | Typical Monthly Premium (Oregon) |
|---|---|---|
| Plan G | Everything except Part B deductible | $220–$270/month |
| Plan N | Most gaps; small copays for office/ER visits | $135–$170/month |
| Plan HDG | High-deductible version of Plan G | $55–$85/month |
(Note: Plan F is no longer available to those new to Medicare after January 1, 2020.)
What You Get With Medicare Supplement
- Freedom to see any doctor or specialist nationwide who accepts Medicare — no referrals, no networks
- Predictable costs: Once you pay your premium, your out-of-pocket exposure is minimal or zero (depending on the plan)
- Guaranteed renewable: The insurer cannot cancel your policy as long as you pay premiums
- Nationwide coverage: Ideal for retirees who travel, snowbird, or have family in multiple states
The Trade-Offs
- Higher monthly premiums compared to most MA plans
- No prescription drug coverage included — you’ll need a separate Part D plan (~$20–$50/month)
- No extra benefits like dental or vision — those require separate policies
- Medical underwriting may apply if you enroll outside your initial open enrollment window
Medicare Supplement is often a good fit for: Those who want maximum flexibility, have ongoing health conditions requiring specialist care, travel frequently, or simply value knowing exactly what their healthcare will cost each month.
A Side-by-Side Comparison
| Feature | Medicare Advantage | Medicare Supplement |
|---|---|---|
| Monthly Premium | Often $0 | $55–$270/month |
| Out-of-Pocket Max | Up to $9,250/year | Near $0 (Plan G) |
| Network Restrictions | Yes (HMO/PPO) | None — any Medicare provider |
| Prescription Drugs | Usually included | Separate Part D needed |
| Dental/Vision | Often included | Separate policies needed |
| Nationwide Coverage | Limited | Yes |
| Prior Authorization | Often required | Not required |
| Annual Plan Changes | Yes | Premiums adjust; benefits stable |
The Question Most People Don’t Ask — But Should
Here’s something I tell every client: Don’t just compare the premiums. Compare the worst-case scenarios.
With Medicare Advantage, if you have a serious illness or hospitalization, your costs could reach $9,250 in a single year. With Plan G, your annual exposure is essentially just the Part B deductible ($257 in 2026) — and after that, the plan covers the rest.
For someone who is generally healthy and rarely uses medical services, Medicare Advantage may save thousands in premiums over the years. For someone managing a chronic condition, seeing multiple specialists, or facing a major health event, a Medicare Supplement plan could save far more.
Why Working With an Independent Broker Changes Everything
Here’s what the television commercials won’t tell you: the Medicare agent calling you after your 65th birthday is almost certainly captive to one or two carriers. They can only sell you what they have — not what’s best for you.
As an independent broker, I work with 20+ Medicare carriers across Advantage plans, Supplements, Part D drug plans, and ancillary products like dental, vision, and hospital indemnity. My job isn’t to push a product — it’s to find the plan that fits your health history, your doctors, your prescriptions, and your budget.
And because Medicare plan premiums are regulated, you pay the same price whether you buy through me or directly from the carrier. The difference is that you get an experienced advisor in your corner — at no extra cost.
