Picking a Medicare plan in 2026 isn’t about finding the cheapest option, it’s about matching your health needs, provider preferences, and tolerance for surprise costs. I’ve spent years helping people navigate these choices, and the difference between a plan that works and one that leaves you frustrated often comes down to understanding what you’re actually paying for. Let me walk you through the real 2026 numbers so you can make a decision without regret.
| Plan | Monthly Premium | Annual Deductible | Max Out-of-Pocket | Best For |
|---|---|---|---|---|
| Medicare Advantage (Part C) Bundles A, B, usually D, plus dental/vision/hearing extras; network-based | $0-$70 (many plans $0, plus you still pay Part B) | Varies by plan; often $0 medical | $9,350 in-network cap (2026 federal max) | Lower monthly cost and extra benefits, if you stay in-network |
| Medigap (Supplement Plan G) Pays most out-of-pocket costs Original Medicare leaves; any Medicare provider | $130-$170 typical (varies by state and age) | $283 Part B deductible only | Effectively the Part B deductible for covered services | Predictable costs and minimal surprise bills |
| Original Medicare (Part A + B) Any doctor/hospital that accepts Medicare; no networks | $0 Part A (if 40+ work quarters) + ~$206 Part B | $1,676 Part A per benefit period + ~$283 Part B | None (no annual cap) | People who want provider freedom and travel often |
| Part D (Prescription Drug) Standalone drug coverage; formularies and tiers vary by plan | $0-$60 (national base ~$36) | Up to $615 (2026 maximum) | $2,100 true out-of-pocket cap on covered drugs (2026) | Anyone on Original Medicare who takes prescriptions |

How to Read This Comparison
Each plan type you see has fundamentally different cost structures. Original Medicare has no monthly premium for Part A (assuming you have 40+ quarters of work history) but charges around $206 for Part B, plus it leaves you exposed to coinsurance and copays with no annual cap. Medicare Advantage looks cheaper at first glance, often with $0 premiums, but that savings comes with network restrictions and a hard $9,350 out-of-pocket ceiling in 2026. Medigap sits in the middle: you keep Original Medicare and add a supplement (Plan G typically runs $130-$170 per month) that fills the gaps. Part D is standalone drug coverage you add to Original Medicare if you don’t use Advantage.
The key insight: the lowest monthly premium doesn’t mean the lowest total cost. A person with multiple chronic conditions and regular prescriptions could spend less with Original Medicare plus Medigap plus Part D than with a $0-premium Advantage plan if they have one expensive medication or see specialists outside the network.
The Real Cost Difference Between Plans
Let’s put numbers on a realistic scenario. Say you’re a 68-year-old taking three maintenance medications and seeing a cardiologist twice yearly. With Original Medicare plus Medigap Plan G and Part D, you’re looking at roughly $206 (Part B) plus $150 (Medigap) plus $36 (Part D) equals $392 per month, or about $4,700 annually in premiums. You’ll hit the Part D coverage cap at $2,100 out-of-pocket on drugs, but your doctor visits and specialist care have almost no surprise costs because Medigap covers what Original Medicare doesn’t.
Now compare that to a $0-premium Advantage plan. Your monthly costs look great at first, but many Advantage plans charge $20-$40 per specialist visit in-network. If you see your cardiologist twice yearly plus your primary care doctor four times, that’s another $120-$240 annually. Your Part D is bundled but often on a narrower formulary, meaning your preferred medication might be on a higher tier. And if you travel and need urgent care out of network, you could face 50% coinsurance instead of Medigap’s minimal copays.
I’ve seen people save $2,000 a year with Medigap, and I’ve seen others save that much with Advantage. The difference hinges on three variables: your prescription costs, your visit frequency, and your willingness to stay in-network.
Who Should Choose Each Plan Type

Choose Original Medicare plus Medigap if you value choice above all else, if you travel frequently, or if you have established relationships with doctors outside typical networks. The lack of an out-of-pocket cap is scary on paper, but Medigap removes that risk for a predictable monthly cost. This setup costs the most in monthly premiums but the least in surprise bills.
Choose Medicare Advantage if you’re comfortable with a network, if you take few or generic medications, and if you want bundled dental, vision, and hearing benefits (which Original Medicare doesn’t cover and Medigap doesn’t either). Advantage makes sense for healthy people or those willing to shift doctors if needed. The $9,350 in-network cap gives you a psychological safety ceiling.
Choose Original Medicare alone only if you take no regular medications and are very healthy. This is rare, because most 66-year-olds on Medicare will eventually benefit from Part D coverage.
Choose standalone Part D only if you’re already on Original Medicare. The $615 deductible and $2,100 out-of-pocket maximum are strict, but many people never hit them if they take one or two generic drugs. Compare Part D plans side by side on Medicare.gov because premiums vary by $40 per month and formularies differ dramatically.
Common Mistakes I See Every Year
First: enrolling in Advantage because the premium is $0 without understanding that you cannot switch back to Medigap after your initial enrollment period without undergoing medical underwriting. If you develop a condition like diabetes or arthritis while on Advantage, you may be denied Medigap later or charged much more. This is a one-way door for many people.
Second: ignoring the Part D formulary. Two plans might both cost $36 per month, but one covers your blood pressure medication at a $5 copay and the other at a $50 copay. Most people don’t check this and end up paying far more than the premium difference would suggest.
Third: assuming you’ll stay healthy and in-network. Life doesn’t cooperate with assumptions. You travel for a grandchild’s birth and need urgent care in a different state. You develop a condition and want to see a specialist who isn’t contracted. Original Medicare plus Medigap costs more upfront but protects against these scenarios.
Fourth: forgetting to account for the Part B premium increase if your Modified Adjusted Gross Income (MAGI) exceeded $97,000 the prior year. Higher earners pay surcharges on Part B, Medigap costs may increase as you age, and Advantage plan premiums can jump year to year. Nothing is truly fixed.
What I’d Choose for Myself
I’m direct about this: I’d choose Original Medicare plus Medigap Plan G plus Part D. The monthly cost of roughly $390-$400 feels like paying for peace of mind. I can see any doctor, I don’t agonize over formularies, and I never worry about surprise bills. If I lived in a rural area or traveled constantly, I’d feel even more certain. But if I were healthy, took one generic blood pressure pill, and lived in a major city with a strong Advantage network, I’d seriously consider a $0 Advantage plan and pocket the premium difference for out-of-pocket costs, knowing I could always switch later if circumstances changed.
Your answer depends on your health, your financial flexibility, and your emotional tolerance for complexity. Use this data as a starting point, then get specific quotes from plans in your zip code. The $50 or $100 per month you save or spend matters over a decade.
