Quick Answer

As of the most recent CMS data, 56.1% of Florida's roughly 5.14 million Medicare beneficiaries are enrolled in Medicare Advantage, above the national average of about 54%. Many Florida counties have 40 or more Medicare Advantage plans to choose from, and a large share are $0-premium plans — which explains the growth, but also why so many people feel overwhelmed at decision time.

Key Takeaways

• 56.1% of Florida Medicare beneficiaries are on Medicare Advantage, vs. ~54% nationally (CMS Medicare Monthly Enrollment, 2024).
• Enrollment varies sharply by county — from 75.1% in Miami-Dade to 47.5% in Palm Beach County — so your local picture may look nothing like the statewide average.
• Medicare Advantage trades lower premiums for provider networks and prior authorization; Original Medicare + a Medigap plan trades higher premiums for nationwide freedom and predictable costs.
• The "right" choice depends on your doctors, prescriptions, travel, and budget — not on which plan advertises the most.
• A free Medicare review compares the specific plans available at your address at no cost.

How Many Floridians Are on Medicare Advantage vs. Original Medicare

Florida has about 5.14 million Medicare beneficiaries, and roughly 2.9 million of them — 56.1% — are enrolled in Medicare Advantage, one of the higher rates in the country (CMS Medicare Monthly Enrollment, 2024). You can see the full state and county breakdown on our Florida Medicare data page.

Enrollment has climbed steadily over the past decade, driven largely by $0-premium plans that bundle extras like dental, vision, and gym memberships. The remaining 43.9% stay on Original Medicare, and most of those pair it with a Medicare Supplement (Medigap) plan plus a Part D drug plan.

That statewide average hides a lot, though. In Palm Beach County, only 47.5% of beneficiaries are on Medicare Advantage — below the state average — while Miami-Dade runs much higher. Where you live changes the math.

What's Driving the Medicare Advantage Growth in Florida

Three things: money, benefits, and marketing.

First, premiums are low. Many Florida Medicare Advantage plans — especially from carriers like Humana, UnitedHealthcare, and Aetna — charge $0 per month beyond your Part B premium. (Everyone still pays the standard Part B premium, $202.90/month in 2026, plus IRMAA for higher earners — see the 2026 cost figures.)

Second, extra benefits matter to people. Most Medicare Advantage plans now include dental cleanings, eyewear allowances, and over-the-counter allowances. Original Medicare covers none of that.

Third, the advertising is relentless. If you watch daytime TV in Florida, you've seen the commercials. They work.

But here's what the ads don't tell you: you're trading lower premiums for network restrictions and prior authorizations. That's not necessarily bad — it's just a trade-off you should make on purpose, not by accident. (Our Medicare Advantage vs. Supplement guide walks through both sides.)

Average Costs: What Florida Seniors Are Actually Paying

Here's the cost picture for 2026.

Medicare Advantage: Many plans run $0–$35/month, with copays for visits and per-day costs for hospital stays. By law, every Medicare Advantage plan caps your annual in-network out-of-pocket spending (a protection Original Medicare doesn't offer), and many Florida plans set their cap below the federal maximum. Always check a specific plan's copays and out-of-pocket limit before enrolling.

Medicare Supplement + Part D: Plan G (the most popular Medigap plan) typically runs about $145–$185/month in South Florida for someone turning 65, depending on age, insurer, and tobacco use. Add roughly $40–$75/month for a standalone Part D drug plan. You pay more per month, but your costs when you actually use care are minimal — just the Part B deductible ($283 in 2026, per CMS) and your drug copays.

Which is better? It depends on your health, your doctors, and whether you travel.

County-by-County Differences: Why Your ZIP Code Matters

Medicare Advantage penetration swings widely across Florida — 75.1% in Miami-Dade, 64.8% in Broward, and 47.5% in Palm Beach County (CMS, 2024). Metro counties also tend to offer the most plans (often 50+), while rural counties offer far fewer.

More options doesn't always mean better options. A lot of my time goes to helping people in West Palm Beach or Boca Raton narrow down plans because the sheer number is paralyzing.

Provider networks shift by county, too — a plan that includes Cleveland Clinic Florida in one county might not contract with your local hospital in another. And if you split time between Florida and another state, it gets trickier: most Medicare Advantage plans only cover emergency and urgent care outside their service area, which is why many snowbirds lean toward Medigap.

The Trade-Off Most People Don't Understand Until It's Too Late

Medicare Advantage plans save you money on premiums. But they manage your access to care through networks, referrals, and prior authorizations.

Need to see a cardiologist? You'll often need a referral first. Want an MRI? The plan may have to approve it. Prefer a specific surgeon? Make sure they're in-network, or you could face large bills.

Original Medicare with a Supplement plan works differently. You can see any doctor in the country who accepts Medicare (most do), with no referrals and no prior approvals. You pay more per month for that freedom, but far fewer surprises.

Neither is universally "right." The decision should match how you actually use healthcare. Timing matters too — review the Medicare enrollment periods so you make changes inside the right window.

Who's Still Choosing Medicare Supplement Plans and Why

Roughly 43.9% of Florida beneficiaries stay on Original Medicare, most paired with a Supplement. Here's who and why:

People with chronic conditions who see multiple specialists. People who winter in Florida but live elsewhere part of the year. People who want predictable costs and dislike insurance approvals. And people who've had a poor experience with a Medicare Advantage network.

Plan G is the go-to for most new enrollees. Plan N costs a bit less (often $115–$145/month in South Florida) but adds small copays. High-deductible Plan G is an option if you're healthy and want catastrophic-only coverage.

One warning: if you try Medicare Advantage first and want to switch to a Supplement later, you may face medical underwriting unless you're within your first year on Medicare or qualify for a guaranteed-issue right. That means an insurer can decline you or charge more based on your health.

The Bottom Line

Florida is a Medicare Advantage stronghold — 56.1% of beneficiaries are enrolled — but "most people" isn't a recommendation. Miami-Dade and Palm Beach County residents face very different plan landscapes, and the right answer turns on your doctors, medications, travel, and budget.

Frequently Asked Questions

Q: Can I switch from Medicare Advantage back to a Medicare Supplement plan? A: Yes, but unless you're in your first 12 months on Medicare Part B or qualify for a special circumstance, insurers can ask health questions and decline you. If you're thinking about trying Medicare Advantage, understand that the door back to Medigap might not stay open.

Q: Do all Medicare Advantage plans in Florida include drug coverage? A: Most do — these are called MAPD plans (Medicare Advantage Prescription Drug plans). A small number don't include drugs, which means you'd need a separate Part D plan. Always confirm before enrolling.

Q: How do I know if my doctor takes a specific Medicare Advantage plan? A: Call your doctor's office and ask which Medicare Advantage plans they're contracted with for the current plan year, then confirm against the plan's provider directory. Networks can change annually, so verify before you enroll and again at renewal. A licensed advisor can check this for you as part of a free review.

Q: Why is Medicare Advantage so much more common in Miami-Dade than Palm Beach County? A: Plan availability, carrier competition, and local provider contracts vary by county, which drives different enrollment patterns — 75.1% in Miami-Dade vs. 47.5% in Palm Beach County (CMS, 2024). It's another reason to compare plans specific to your ZIP code rather than rely on statewide averages.
