In 2026, more than 33 million Americans are enrolled in Medicare Advantage, representing roughly 49% of all Medicare beneficiaries. That number has doubled in the last decade.
But popularity does not equal the right fit for every dad.
This comparison breaks down what you actually get with each option, what each one costs in the real world, and the specific situations where one beats the other. No fluff, no sales pitch.

Original Medicare (Parts A and B) is a government-run program. You get a Medicare card, and any doctor or hospital that accepts Medicare will see you, anywhere in the country. You pay deductibles and coinsurance with no annual cap. Medicare Advantage (Part C) is private insurance that replaces Original Medicare. A private insurer covers everything Parts A and B cover, usually adds extras like dental and vision, and often has a $0 premium. The tradeoff: you're in a network, and prior authorization requirements apply to many services.Both options require you to still pay your Part B premium ($185/month in 2026).
What You Get With Original Medicare
Original Medicare covers:
- All medically necessary inpatient hospital care (Part A)
- Outpatient services, doctor visits, lab work, durable medical equipment (Part B)
- Preventive services at $0 cost to you
- Mental health services
- Some home health care and hospice
- Part A deductible: $1,632 per benefit period
- Part B deductible: $257 per year
- Part B coinsurance: 20% of Medicare-approved costs, with no annual out-of-pocket maximum
That last point is critical. With Original Medicare alone, a serious cancer diagnosis, a major surgery, or a long hospital stay could cost you $20,000 or $50,000 or more in a single year. There is no ceiling.
This is why most people who stay with Original Medicare add either a Medigap supplement or a standalone Part D drug plan.
Original Medicare does NOT include:- Prescription drug coverage (you need a separate Part D plan)
- Dental
- Vision
- Hearing
- Long-term care
What You Get With Medicare Advantage
Medicare Advantage plans are sold by private insurers. In 2026, there are hundreds of plan options nationwide, varying significantly by county.
By law, every Medicare Advantage plan must cover everything Parts A and B cover. Most plans go further:
- Prescription drug coverage is included in most plans (called MAPD plans)
- Dental, vision, and hearing are commonly included, though coverage limits vary
- Extra benefits in 2026 include things like gym memberships, meal delivery after hospitalization, transportation to medical appointments, and over-the-counter allowances
- Annual out-of-pocket maximum: In 2026, the statutory limit is $9,350 for in-network care. Many plans set lower maximums.
- Many plans have $0 monthly premiums (you still pay Part B)
- Copays per service (typically $10 to $50 for primary care, higher for specialists)
- Deductibles vary by plan
In rural areas, thin networks can be a real problem. In major metro areas, most Medicare Advantage networks are broad enough that the restriction rarely matters.
Adding Medigap to Original Medicare
If you choose Original Medicare, the standard move is to add a Medigap (Medicare Supplement) policy.
Medigap Plan G is the most widely purchased new policy in 2026 since Plan F was discontinued for new enrollees. Plan G covers:
- Part A coinsurance and hospital costs up to 365 extra days
- Part B coinsurance or copayment (the 20%)
- Part A deductible ($1,632)
- Skilled nursing facility coinsurance
- Part B excess charges
- Foreign travel emergency coverage (80% up to plan limits)
With Plan G, your annual maximum out-of-pocket exposure is essentially the Part B deductible of $257. After that, you pay almost nothing for covered services for the rest of the year.
You still need a standalone Part D drug plan, which averages around $43 per month.
Total monthly cost for Original Medicare + Plan G + Part D: roughly $185 (Part B) + $150 (Plan G estimate) + $43 (Part D) = $378 per month.Side-by-Side Comparison
| Factor | Original Medicare + Medigap G + Part D | Medicare Advantage (MAPD) |
|---|---|---|
| Monthly premium | ~$378/month (varies) | ~$185-$220/month (Part B + plan premium) |
| Out-of-pocket maximum | Effectively ~$257/year (after Plan G) | Up to $9,350/year in-network |
| Network restrictions | None (any Medicare provider nationwide) | In-network required for most care |
| Dental/vision/hearing | Not included | Often included (limits vary) |
| Prescription coverage | Separate Part D plan | Usually included in plan |
| Prior authorization | Rarely required | Common for specialists, surgeries, imaging |
| Premium increases | Yes, Medigap rates rise with age | Can change annually |
| Predictability | Very high | Moderate (copay per service) |
Who Is Better Served by Original Medicare + Medigap?
Original Medicare with a Medigap supplement tends to work best for dads who:
Travel frequently or split time between states. Snowbirds and frequent travelers need a plan that works everywhere. Medigap works with any Medicare provider in the country with zero network hassle. Have complex or chronic health needs. If you see multiple specialists, have an ongoing condition, or want the absolute lowest friction when accessing care, Medigap removes nearly every financial barrier and most administrative ones. Value predictability over low premiums. Yes, you'll pay more per month. But once you hit that $257 Part B deductible, your exposure is essentially zero for the rest of the year. If you're someone who doesn't like financial surprises, that peace of mind has real value. Have strong relationships with specific doctors. If your cardiologist, oncologist, or orthopedic surgeon is the one you've trusted for years, you want to make sure they accept your plan. With Medigap, if they accept Medicare, they accept you.Who Is Better Served by Medicare Advantage?
Medicare Advantage tends to work best for dads who:
Are generally healthy and use healthcare moderately. If you're visiting your primary care doctor twice a year and picking up a couple of prescriptions, a $0 premium MAPD plan with $20 copays and included dental is probably saving you $100 to $200 per month versus the Medigap route. Live in an area with strong Medicare Advantage networks. In major metro areas, most Medicare Advantage plans include the major hospital systems and a wide range of specialists. If your preferred doctors are in-network, the constraint barely matters. Want extra benefits without extra cost. Dental, vision, hearing, gym memberships, OTC allowances: these benefits have real value. A dentist visit can cost $300 to $500 out of pocket. If your Medicare Advantage plan covers two cleanings and an exam per year, that's meaningful savings. Are comfortable with some administrative steps. Prior authorizations are more common with Medicare Advantage. For most routine care, this is a minor inconvenience. For complex care, it can occasionally cause delays.The Switching Problem: Think Long-Term
Here is the most important strategic point in this entire comparison, and most dads miss it.
When you first enroll in Medicare at 65, you can switch from Medicare Advantage to Medigap freely during your 6-month Medigap Open Enrollment Period. During that window, insurers cannot deny you coverage or charge higher premiums based on your health.
After that window closes, Medigap insurers in most states can underwrite you. That means if you develop cancer, heart disease, or any number of conditions, you could be denied a Medigap policy or charged substantially higher premiums.This matters because the most common path is this: a dad enrolls in a $0 Medicare Advantage plan at 65 because the low premium is attractive. At 70 or 75, after a serious diagnosis, he tries to switch to Medigap for better coverage and discovers he cannot get Plan G at a reasonable price or at all.
The bottom line: think about what you want your coverage to look like at 75 or 80, not just at 65. If you think you might want Medigap eventually, getting it at 65 during guaranteed issue is almost always the right call.

The Part D Factor: Drugs Matter More Than You Think
If you're on medications, the drug formulary of your plan can easily override everything else in this comparison.
Under Medicare Advantage MAPD plans, your drug coverage is bundled. The plan's formulary (the list of covered drugs) is set by the insurer, and drugs are grouped into tiers with different copay levels.
Under Original Medicare + a standalone Part D plan, you choose the Part D plan separately and can pick the one that covers your specific medications most favorably.
In 2026, the new $2,000 annual cap on Part D out-of-pocket costs applies to both standalone Part D plans and MAPD plans. This is a significant improvement for dads on expensive specialty medications.
Before choosing any plan, run your specific medications through the plan's formulary tool and compare your estimated annual drug cost. This single step can swing the comparison by $1,000 or more per year.
3 Questions to Ask Before You Decide
1. Do my current doctors accept this plan?Call your primary care doctor and any specialists you see regularly. Ask specifically: "Do you accept [Plan Name] from [Insurer]?" Don't assume. Networks change every year.
2. Are my medications covered, and at what tier?Use Medicare.gov's plan comparison tool or the insurer's website. Enter every prescription you take and see your estimated annual drug cost for each plan.
3. What is my realistic total annual cost?Add up premiums times 12, plus estimated copays based on how often you typically use healthcare, plus the deductible. For Medigap, your total is relatively easy to project. For Medicare Advantage, model a scenario where you have a moderate health event, like an inpatient hospital stay or an outpatient surgery.
The Bottom Line
Neither option is universally better. The right choice depends on your health, your location, your medications, your travel habits, and your financial priorities.
What is universally true: the decision you make at 65 can be difficult or expensive to reverse later. Take the time to get it right.
