Florida's Medicare Advantage Landscape: 600 Plans, 22 Carriers, and What It Means for 2027

Florida is the most important Medicare Advantage market in the country. Not the biggest by enrollment — California holds that title — but the most contested. Twenty-two parent organizations are fighting over 67 counties, deploying 600 plans in a state where the over-65 population grows by roughly 1,000 people per day. The carriers know what that demographic curve looks like. The question is whether beneficiaries know what the carriers are doing.

I've pulled every data point I could find from the CMS Medicare Plan Finder landscape files and CMS Medicare Advantage enrollment data. Here's what Florida's Medicare Advantage battlefield actually looks like.

Who Controls the Florida Market?

Not a surprise to anyone who follows the industry: the Big Five dominate. But the concentration is more extreme than most people realize.

Two things jump out. First: Humana, UnitedHealth, and Guidewell (Florida Blue's parent) are the only three organizations serving all 68 service areas. Everyone else cherry-picks. Devoted Health, despite having 76 plans, only operates in 27 counties — all of them metro or suburban. Athena Healthcare has 24 plans in just 10 counties.

Second: look at the premium spread. Elevance averages 0.47 dollars per month. Guidewell averages 23.87 dollars. That's not a typo. Elevance is running near-zero-premium plans to capture market share, while Florida Blue is charging real money for its PPO-heavy portfolio. If you're a senior in a rural county where only Guidewell and Humana show up, your "choice" comes with a price tag.

What Types of Plans Dominate?

Florida's plan mix tells you where the money is. HMO plans dominate the standard Medicare Advantage space, but the Special Needs Plan (SNP) market is massive — and it's where carriers are making their biggest bets heading into 2027.

The D-SNP number is the one to watch: 141 plans from 13 organizations across 66 of Florida's 67 counties. These are Dual-Eligible Special Needs Plans, designed for people on both Medicare and Medicaid. Carriers love D-SNPs because they get paid from both programs — Medicare Advantage payments plus Medicaid managed care payments. The population is sicker and more expensive, but the double revenue stream makes the math work.

With 99 C-SNP plans (Chronic Condition Special Needs Plans) from 9 organizations, Florida's chronic disease market is also heavily targeted. These plans serve beneficiaries with conditions like diabetes, heart failure, and chronic lung disease. The average premium is just 0.36 dollars per month — functionally free. Carriers are using zero-premium C-SNPs as a competitive weapon to lock in high-acuity members.

Where Are the Beneficiaries? Follow the Enrollment.

Florida's Medicare Advantage enrollment is concentrated in the same places everything in Florida is concentrated: the I-4 corridor and South Florida's coastal metros. The top 10 counties account for the vast majority of enrollment.

Miami-Dade's 469,876 enrollees is a staggering number. That's more people on Medicare Advantage in a single county than the entire Medicare populations of Wyoming, Vermont, and Alaska combined. It's also why every carrier wants a presence in South Florida — and why the competition for brokers, providers, and marketing airtime in Miami is the most intense in the nation.

But now look at the other end of the spectrum.

The Rural Counties Carriers Don't Want to Talk About

While Miami-Dade enjoys 1,586 plan-county options, the story in Florida's rural counties is dramatically different.

Lafayette County has 1,188 Medicare Advantage enrollees and roughly 1,018 plan-county combinations. That sounds like a lot of options until you realize that most of those are statewide PDPs, Regional PPOs, and PPOs that technically cover the county but have zero local provider network. The actual number of HMO plans — the ones with the richest benefits and lowest premiums — available to a Lafayette County resident is a fraction of what's available in Palm Beach.

This is the two-Florida problem. A Medicare beneficiary in Palm Beach has 1,677 plan options, a dozen carriers actively competing for their enrollment, and a provider network that includes some of the best-funded health systems in the state. A beneficiary in Lafayette County has a handful of statewide plans, one or two carriers who actually maintain a local network, and a hospital drive that might be 45 minutes each way.

Hospital Access: The Other Half of the Equation

A Medicare Advantage plan is only as good as the providers in its network. Florida has a mix of major health systems, but the distribution is as uneven as the plan landscape.

Among the 25 hospitals reviewed in CMS Provider Data, the quality ratings tell an interesting story. Baptist Hospital of Miami earned a 4-star CMS rating. Lee Memorial Hospital in Fort Myers and AdventHealth New Smyrna Beach also earned 4 stars. But Jackson Health System — the largest safety-net hospital in South Florida — has a 1-star rating. Parrish Medical Center in Titusville and North Shore Medical Center in Miami also carry 1-star ratings.

For Medicare Advantage enrollees, hospital star ratings matter because many MA plans use narrow networks. If your plan's only in-network hospital has a 1-star quality rating, your "free premium" is extracting a different kind of cost.

What Does CMS's 2.48% Rate Increase Mean for Florida Specifically?

CMS finalized a 2.48% net average payment increase for Medicare Advantage in 2027 — over 13 billion dollars nationally, as we covered in our rate announcement analysis. For Florida, this matters more than for most states because of the sheer volume of enrollment.

With total MA enrollment across Florida's 67 counties exceeding 4.5 million beneficiaries (by our count from CMS county-level enrollment data), even a small percentage increase in per-member payments translates to hundreds of millions in additional carrier revenue flowing into the state. The question — as always — is whether that revenue will flow through to beneficiary benefits or pool in carrier margins.

History suggests the latter. Mizuho analyst Ann Hynes stated the rate increase "should allow industry to expand margins when coupled with benefit cuts." Florida beneficiaries should watch their September Annual Notice of Change documents carefully. Plan premiums, copay structures, and supplemental benefits (dental, vision, hearing, fitness) are all on the table for adjustment.

What Should Florida Beneficiaries Watch For in 2027?

1. Network changes in rural counties. With the CMS rate increase favoring larger carriers who can spread risk, smaller regional plans in Florida's Panhandle may face pressure to narrow networks or exit markets. Watch for provider directory changes in counties with fewer than 1,100 plan options.

2. D-SNP enrollment coordination. Florida has 141 D-SNP plans, and the proposed Medicaid work requirements (covered in our companion analysis) could disrupt Medicaid eligibility for the dual-eligible population these plans serve. If Medicaid administrative churn increases, D-SNP enrollment stability will suffer.

3. Premium compression in HMOs. The average HMO premium in Florida is 1.92 dollars per month. Many plans carry zero-dollar premiums. This is not sustainable if benefit costs continue to rise. Expect some zero-premium HMOs to introduce nominal premiums or reduce supplemental benefits in 2027.

4. Guidewell's pricing gap. Florida Blue's parent company, Guidewell, averages 23.87 dollars per month — nearly five times the next most expensive statewide carrier. That pricing reflects a heavier PPO portfolio, but it also creates vulnerability. If Humana or UnitedHealth introduce competitive PPO products in Guidewell's strongest counties, the incumbent could lose significant market share.

5. The Annual Election Period (October 15 - December 7, 2026). Every data point in this article will matter most during AEP, when Florida's 4.5 million+ MA beneficiaries choose their 2027 plans. Carriers will spend hundreds of millions on TV ads, mailers, and agent commissions. The ones who read this analysis will make better decisions.
