- County seat: Key West — southernmost city in the continental U.S.
- Population: ~74,000
- ACA carriers: Florida Blue, Ambetter
- Florida Keys: 113-mile chain of islands in the Gulf of Mexico and Atlantic
- Healthcare access challenge: no trauma center in the Keys
- High cost of living; significant hospitality and tourism workforce
Monroe County is unlike any other county in Florida — and perhaps unlike any other county in the continental United States. Stretching 110 miles from Card Sound to the Dry Tortugas, the Florida Keys form an arc of coral limestone islands connecting the Gulf of Mexico to the Atlantic Ocean. Key West, the southernmost city in the continental U.S., is the county seat and the cultural capital of a county that has more in common with the Caribbean than with mainland Florida.
The Keys' Gulf side — the Florida Bay and Gulf of Mexico — is a world-class shallow-water fishing destination. Backcountry flats fishing for bonefish, tarpon, and permit in the Gulf waters north of the Keys is considered some of the finest saltwater fly fishing in the world. Charter captains, dive operators, and fishing guides represent a significant self-employed workforce throughout the Keys.
Monroe County's healthcare situation is uniquely challenging. The Florida Keys have no Level I or Level II Trauma Center. The Lower Keys Medical Center in Key West handles emergencies and primary care, but serious trauma, cardiac events, and complex surgeries require transport (by helicopter or air ambulance) to Miami-Dade County. This geographic isolation makes health insurance selection — particularly understanding emergency air transport coverage — critically important for Keys residents.
ACA Marketplace Plans in Monroe County
Monroe County has two ACA marketplace carriers in 2026: Florida Blue and Ambetter. The Keys' geographic isolation limits carrier competition. Compare both at HealthCare.gov using your Key West, Marathon, or Islamorada zip code.
Florida Blue
Blue Cross Blue Shield of Florida — statewide network including Lower Keys Medical Center and Miami-Dade specialty facilities for air transport situations
Ambetter
Ambetter from Sunshine Health — competitive pricing for Keys residents; verify coverage for Miami-Dade air transport situations before enrolling
2026 ACA Subsidy Reference
The following income thresholds govern 2026 ACA subsidy eligibility (using 2025 FPL). Florida has not expanded Medicaid — adults in Monroe County below 100% FPL without dependent children fall into the coverage gap.
| Household Size | 100% FPL | 150% FPL | 200% FPL | 300% FPL | 400% FPL |
|---|
| 1 person | $15,060 | $22,590 | $30,120 | $45,180 | $60,240 |
| 2 people | $20,440 | $30,660 | $40,880 | $61,320 | $81,760 |
| 3 people | $25,820 | $38,730 | $51,640 | $77,460 | $103,280 |
| 4 people | $31,200 | $46,800 | $62,400 | $93,600 | $124,800 |
2026 ACA Cost LimitsOut-of-pocket maximum: $9,200 individual / $18,400 family. Affordability threshold: 8.39% of household income. Subsidies available at any income level if the benchmark Silver plan exceeds this percentage of your income.
Keys Island Living: Healthcare and Coverage Realities
Lower Keys Medical Center (Key West) and Fishermen's Community Hospital (Marathon) are the primary hospitals in Monroe County. Both handle emergency and primary care; neither can manage serious trauma, complex cardiac events, or major surgery. Air transport to Jackson Memorial Hospital, Baptist Hospital, or another Miami-Dade facility is the standard protocol for serious emergencies. Ensure your ACA plan covers air ambulance transport and Miami-Dade hospitals — this is not a theoretical concern in the Keys.
Key West's hospitality economy — restaurants, bars, hotels, charter boats, dive shops — employs thousands of workers who lack employer-sponsored insurance. The cost of living in Key West is among the highest in Florida, meaning many hospitality workers earn enough to be above some subsidy thresholds but not enough to afford full-price premiums comfortably. ACA subsidy calculations are particularly important for this workforce.
The Keys also have a substantial seasonal and part-time population — residents who split time between the Keys and other states or seasonal workers who come for high season. If Florida (specifically Monroe County) is your primary legal residence, you enroll in Florida's ACA marketplace with your Keys zip code. Snowbirds who primarily reside elsewhere should enroll in their primary state's marketplace.
Florida Has Not Expanded MedicaidAdults in Monroe County earning below 100% FPL ($15,060 single adult in 2026) do not qualify for Medicaid without dependent children or disability — and cannot receive ACA marketplace subsidies. This is Florida's Medicaid coverage gap. Call to explore available options.

Frequently Asked Questions
What ACA health insurance plans cover the Florida Keys?
Monroe County ACA marketplace carriers for 2026 include Florida Blue and Ambetter. Use your Key West, Marathon, or Islamorada zip code on HealthCare.gov. Two carriers provide some premium competition. Given the Keys' distance from major medical centers, verify that your plan covers air ambulance transport and Miami-Dade specialty hospitals before enrolling.
If I have a medical emergency in the Florida Keys, where do I go?
Lower Keys Medical Center (Key West) and Fishermen's Community Hospital (Marathon) handle local emergencies. For serious trauma, cardiac emergencies, or complex surgical cases, the standard protocol is helicopter transport to Jackson Memorial Hospital or another Miami-Dade Level I Trauma Center. Ensure your ACA plan covers both the Keys hospitals and Miami-Dade facilities — and understand your air ambulance coverage.
Can hospitality workers in Key West get affordable health insurance?
Yes. Key West hospitality workers who earn between 100% and 400% FPL qualify for ACA premium tax credits. Despite the Keys' high cost of living, ACA subsidies are calculated on income relative to the federal poverty level — not local cost of living. A restaurant worker earning $30,000 in Key West qualifies for the same subsidy as a worker earning $30,000 in rural North Florida. Call for help estimating your subsidy.
I'm a charter captain in the Keys — what health insurance do I need?
Charter captains in the Keys who are self-employed (running their own boat) qualify for ACA marketplace plans. You can deduct 100% of health insurance premiums as a business expense. If your net annual income falls between 100% and 400% FPL, you receive premium tax credits in addition to the tax deduction. Given the Keys' geographic isolation, consider plans with the most comprehensive emergency and out-of-county coverage — Florida Blue's statewide network includes Miami-Dade trauma centers.
