What's in this guide
Once you have Part A and Part B, many people compare two approaches: receiving benefits through Medicare Advantage, or keeping Original Medicare and adding a Medigap policy and usually a standalone Part D plan. Eligibility, enrollment timing, underwriting, plan availability, and personal needs all matter.
The two paths, in one minute
Medicare Advantage (Part C) is another way to receive your Part A and Part B benefits through a private plan. Many plans include Part D drug coverage and may include extra benefits such as dental, vision, or hearing. Plans may use provider networks and can charge deductibles, copays, or coinsurance. You must keep paying your Part B premium.
Medigap (Medicare Supplement) works alongside Original Medicare and pays much of what Medicare leaves behind, deductibles, copays, coinsurance. You can see any doctor in the country that accepts Medicare, with no networks. In exchange, you pay a monthly premium, and you add a separate Part D plan for prescriptions.
Side by side: cost, doctors, travel, drugs, extras
- Monthly premium: Advantage is usually lower (often $0). Medigap has a real monthly premium.
- Costs when you use care: Advantage plans may charge deductibles, copays, or coinsurance. Medigap policies cover some or most Original Medicare cost sharing, depending on the policy.
- Choice of doctors: Many Advantage plans use provider networks, with rules that vary by plan type. Medigap lets you see any provider nationwide that accepts Medicare.
- Travel / snowbirds: Medigap works with providers nationwide that accept Medicare. Advantage travel and out-of-network rules vary by plan.
- Prescriptions: Advantage usually includes Part D. Medigap does not, you add a standalone Part D plan.
- Extras (dental, vision, hearing, OTC): Often built into Advantage; generally not part of Medigap.
Medicare Advantage and Medigap handle provider access, monthly premiums, and cost sharing differently. Compare the specific options against how you use care.

Who each one tends to fit
Medicare Advantage may fit people who prefer a lower monthly plan premium, value bundled benefits, and are comfortable with the plan's provider and service-area rules.
Medigap often fits people who want predictable, stable costs, want to keep specific doctors or specialists without network worries, travel or spend part of the year out of state, and don't mind a monthly premium for that peace of mind.
The switching catch most people miss
When you're 65 or older, your six-month Medigap Open Enrollment Period starts the first month you have Part B. During that period, an insurer can't use medical underwriting to deny you or charge more because of your health history. Outside that period, underwriting may apply unless you have a federal or Florida guaranteed-issue right. Some people also have a Medicare Advantage trial right. Check your exact situation before dropping any coverage.
A few Florida notes
- Compare for your address. Plan availability, networks, and costs vary by county and ZIP code.
- Snowbirds should check travel rules. Compare how each option handles routine, urgent, and emergency care away from home.
- Check your doctors first. Before choosing Advantage, confirm your Gulf Coast providers are in the plan's network.
- Florida has additional Medigap protections. State rules include an enrollment opportunity after certain employer group coverage ends and rights for eligible people under 65. Confirm the timing before applying.
Quick questions, quick answers
Neither is universally better. Medicare Advantage plans vary in premiums, networks, cost sharing, prior authorization, drug coverage, and additional benefits. Medigap works with Original Medicare, has a separate premium, and helps pay specified deductibles and coinsurance; it doesn't include drug coverage. Eligibility, timing, doctors, prescriptions, travel, and total costs all matter.
Sometimes. Outside your Medigap Open Enrollment Period, medical underwriting may apply unless you have a federal or Florida guaranteed-issue right, such as certain trial rights or protections after other coverage ends. Check your eligibility before dropping coverage.
No. A Medigap (Medicare Supplement) policy does not include prescription drug coverage, so most people pair it with a standalone Part D drug plan. Medicare Advantage plans, by contrast, usually build prescription coverage in.
Medicare Advantage usually has a lower (sometimes $0) monthly premium, with costs coming as copays when you use care. Medigap has a higher monthly premium but more predictable out-of-pocket costs. 'Cheaper' depends on how much care you use and how much certainty you want, which is exactly what a side-by-side comparison sorts out.
