Medicare Advantage Plans in Nassau County Florida — Fernandina Beach and Yulee 2026

By the Florida Plan Finder Team · Licensed Florida Health Insurance Producer · NPN #21249133 · Last Updated: May 2026

Key Takeaways

Nassau County has a limited Medicare Advantage carrier market — primarily Florida Blue, with Humana and UnitedHealthcare in limited availability.
The narrow carrier field makes comparing Medicare Advantage against Medigap especially important for Fernandina Beach and Yulee seniors.
Baptist Health Nassau University Medical Center is the county's primary hospital; Jacksonville provides advanced specialty care access.
Proximity to Jacksonville gives Nassau County seniors access to major health systems — but HMO plans may not cover those facilities in-network.
PPO plans or Original Medicare + Medigap are strongly recommended for part-year residents and those who regularly use Jacksonville providers.
Most Florida Blue plans include dental, vision, OTC allowances, and transportation benefits even at $0 premium.

Nassau County is one of Florida's fastest-growing suburban counties — a Jacksonville bedroom community and resort destination wrapped in one. Fernandina Beach, on Amelia Island, draws affluent retirees who value the area's historic character, natural beauty, and proximity to Jacksonville. Yulee and the U.S. 17 corridor serve the county's rapidly growing suburban population of families and retirees moving outward from Duval County. What Nassau County lacks — especially compared to Duval — is a robust Medicare Advantage carrier market. Understanding your Medicare options here means recognizing both what is available locally and how proximity to Jacksonville can expand your practical access to care.

Nassau County Hospital and Jacksonville Specialty Care Access

Baptist Health Nassau University Medical Center (formerly Baptist Medical Center Nassau) is Nassau County's primary hospital, located in Fernandina Beach. The facility offers emergency services, general medical and surgical care, and a growing range of outpatient services. It operates within the Baptist Health system, which provides a critical benefit for Nassau County residents: seamless referral pathways to Baptist Health's major Jacksonville campuses for specialty care.

For complex or advanced medical needs — cardiac surgery, oncology, neurology, transplant medicine — Nassau County seniors reliably access Jacksonville's larger health systems. The major options include:

Baptist Health Jacksonville: The flagship Baptist Health campus, with a full range of specialty services, including the Baptist Heart Specialists programs and the Baptist MD Anderson Cancer Center.
UF Health Jacksonville: The University of Florida's academic medical center in Jacksonville, offering subspecialty care, research programs, and Level I Trauma services.
Mayo Clinic Florida (Jacksonville): Located in Duval County, Mayo Clinic provides subspecialty and second-opinion services. Some Medicare Advantage plans in Nassau County include Mayo Clinic in their networks — others do not.

This Jacksonville dependency is central to the Medicare Advantage plan selection question for Nassau County seniors. If your specialists practice in Duval County, your plan must include those Jacksonville providers in-network for you to use them without out-of-pocket cost-sharing.

Mayo Clinic Network Access Mayo Clinic Florida in Jacksonville does not contract with all Medicare Advantage plans. If you use or plan to use Mayo Clinic for care, verify that your specific plan includes Mayo Clinic in its network before enrolling. Original Medicare is accepted at Mayo Clinic Florida and covers your care with standard cost-sharing.

2026 Medicare Advantage Carriers in Nassau County

Nassau County's Medicare Advantage market is noticeably thinner than neighboring Duval County's. For 2026, the available carriers are:

Florida Blue (HMO and PPO): Florida Blue is the clear dominant carrier in Nassau County, typically offering a $0-premium HMO and a PPO option. Network coverage extends into Jacksonville through Florida Blue's statewide network. Dental, vision, OTC, and transportation benefits included.
Humana (HMO — limited availability): Humana offers an HMO option in Nassau County with limited plan availability and network depth. Supplemental benefits including SilverSneakers and OTC allowances are included. Confirm specific plan availability for your Nassau County zip code.
UnitedHealthcare (PPO — limited availability): UHC offers a PPO in Nassau County with access to its national network, which is particularly valuable for part-year residents and those who use Jacksonville or out-of-state providers. Limited local network depth compared to Florida Blue.

With three carriers — and only one operating at full competition — Nassau County is among Florida's more constrained Medicare Advantage markets. This market structure is a real consideration: limited competition can mean less aggressive pricing and fewer plan options to compare.

2026 Plan Comparison — Nassau County

Carrier	Plan Types	Typical Monthly Premium	Key Benefits	Best For
Florida Blue	HMO, PPO	$0–$60	Dental, vision, OTC, hearing, transportation	Most Nassau County seniors — broadest local network
Humana	HMO (limited)	$0–$45	SilverSneakers, OTC, dental, vision	Active seniors; confirm zip code availability
UnitedHealthcare	PPO (limited)	$30–$90	National network, AARP, Renew Active	Travelers, Jacksonville specialist users
Medigap Plan G + Part D	Supplement	$130–$210+	Nationwide access, any Medicare provider	Complex needs, Mayo Clinic, out-of-state travel

When Medigap Makes More Sense in Nassau County

Nassau County's limited carrier market means that Medicare Advantage may not offer enough plan variety to find the right fit for every senior. Here are the situations where Original Medicare plus a Medigap supplement is likely the better choice:

You regularly use Jacksonville specialists. If your cardiologist, oncologist, or neurologist is at a Jacksonville hospital or clinic, an HMO plan centered on Nassau County may not include them in-network. Medigap + Original Medicare accepts any Medicare provider — in Nassau County, Jacksonville, or anywhere in the country.
You want Mayo Clinic access. Mayo Clinic Florida does not participate in all Medicare Advantage networks. If Mayo Clinic is your preferred provider for subspecialty care, Original Medicare is the most reliable path.
You are a part-year resident or frequent traveler. Medigap Plan G provides true nationwide access — no network to navigate, no prior authorization for routine care when you are up north. An HMO plan covers only emergencies outside its service area.
You have complex or chronic conditions. Medigap Plan G covers virtually all Medicare cost-sharing after the Part B deductible. For high utilizers, cost predictability often outweighs the supplemental benefits of Medicare Advantage.

The primary trade-offs with Medigap: the monthly premium (typically $130–$210+), plus a separate Part D premium for drug coverage, plus separate dental and vision policies if you want those benefits. For many Nassau County seniors, the freedom and predictability are worth the additional premium outlay.

Florida Blue PPO as a Middle Ground If you are not ready to commit to Medigap but want more flexibility than an HMO provides, Florida Blue's PPO in Nassau County is a practical middle path. You retain supplemental benefits (dental, vision, OTC) while gaining access to out-of-network Jacksonville providers at a higher cost share — a meaningful improvement over HMO coverage for seniors who routinely cross the Duval County line for care.

Key Benefits Available in Nassau County MA Plans

Even within Nassau County's limited carrier field, Florida Blue and Humana offer meaningful supplemental benefits not covered by Original Medicare:

OTC Allowance: Most Florida Blue plans include a quarterly OTC credit ($50–$125/quarter) for eligible health products at CVS, Walgreens, or by mail-order. Humana typically offers a similar allowance.
Dental: Preventive dental (cleanings, X-rays, exams) is included at no extra cost on most Florida Blue and Humana plans in Nassau County. Enhanced dental coverage for fillings and major restorative care may require a higher-tier plan.
Vision: Routine annual eye exams and a glasses or contact lens allowance ($100–$200/year) are standard on the leading plans.
Hearing: Most Florida Blue plans in Nassau County include annual hearing exams and a hearing aid benefit. Coverage amounts vary by specific plan — check the Evidence of Coverage.
Transportation: Non-emergency medical transportation is included on many plans. For Fernandina Beach and Yulee seniors without a car or who cannot drive to medical appointments, this benefit can reduce real logistical barriers to care.
Fitness: SilverSneakers (Humana) and Silver&Fit (Florida Blue) provide gym access at participating fitness centers. Locations in Nassau County and accessible Jacksonville gyms are eligible.

PPO Plans and Snowbird Considerations for Nassau County

Amelia Island and the Fernandina Beach area attract a resort-retirement community — including a meaningful number of part-year residents who split time between Nassau County and a northern home state. For these snowbirds and frequent travelers, the Medicare Advantage plan type decision has real financial consequences.

A Florida Blue HMO in Nassau County provides no coverage for non-emergency care when you are in Georgia, New York, or Maine. An emergency is always covered nationally, but a non-emergency doctor visit or specialist appointment outside the service area is not. For part-year residents, the practical solutions are:

Florida Blue PPO: The most accessible out-of-state option within the Medicare Advantage framework for Nassau County seniors. You pay more when seeing out-of-network providers, but care is covered. You retain dental, vision, and OTC benefits.
UnitedHealthcare PPO (limited availability): UHC's national PPO network is broad and may offer better out-of-state access than Florida Blue's PPO depending on the specific states you frequent. Confirm availability for your Nassau County zip code.
Original Medicare + Medigap Plan G or N: The gold standard for nationwide access. Accepted at any Medicare provider in the country, including all licensed hospitals and physicians. Add a Part D plan for drugs. No dental/vision supplemental — those require separate policies.

Frequently Asked Questions

What Medicare Advantage plans are available in Nassau County Florida?

In 2026, Nassau County seniors can access Florida Blue (HMO and PPO), Humana (HMO — limited availability), and UnitedHealthcare (PPO — limited availability). Florida Blue is by far the dominant carrier in Nassau County. Given the limited competition, comparing Medicare Advantage against a Medigap supplement is especially important for Fernandina Beach and Yulee residents.

Can Nassau County Medicare Advantage members access Jacksonville hospitals?

Many Medicare Advantage plans in Nassau County include major Jacksonville hospitals in their networks — particularly Baptist Health facilities and UF Health Jacksonville. However, network access varies by plan, and some locally focused HMO plans may not include all Jacksonville providers. Always verify your specific plan's provider directory before enrolling if you plan to use Jacksonville facilities regularly.

Is Medigap a better option than Medicare Advantage in Nassau County?

For many Nassau County seniors, yes — especially those who regularly access Jacksonville for specialist care or who travel frequently. Original Medicare with a Medigap Plan G or Plan N is accepted at any Medicare provider nationwide, including all Jacksonville hospitals and UF Health. You pay a monthly Medigap premium (typically $130–$200+ depending on age) but gain true nationwide access and no prior authorization requirements. Add a separate Part D drug plan to complete your coverage.

Which hospital is in Nassau County for Medicare patients?

Baptist Health Nassau University Medical Center (formerly Baptist Medical Center Nassau) is Nassau County's primary hospital, located in Fernandina Beach. It provides emergency care, general surgery, and outpatient services. For advanced specialty care — cardiology, oncology, complex surgery — most Nassau County seniors use Baptist Health's Jacksonville campuses or UF Health Jacksonville.

Are there PPO Medicare Advantage plans available in Nassau County?

Yes. Florida Blue offers a PPO option in Nassau County, and UnitedHealthcare has a PPO with limited availability. PPO plans are strongly recommended for Nassau County seniors who regularly access Jacksonville providers or who spend time outside Florida. A PPO allows you to see out-of-network providers at a higher cost share, giving you more flexibility than an HMO without fully switching to Original Medicare.
