Clay County is Jacksonville's southern suburban collar — a sprawling community of planned neighborhoods, waterfront communities along Fleming Island, rural homesteads near Middleburg, and the county seat of Green Cove Springs on the St. Johns River. The county has grown steadily for decades, attracting families priced out of Duval County who want suburban square footage within commuting distance of Jacksonville's job centers.
Naval Air Station Jacksonville's proximity has given Clay County a significant military and veteran population. Active duty service members and their dependents typically use TRICARE rather than ACA marketplace plans. But the military community also generates a substantial population of veterans, separated servicemembers, military spouses, and civilian contractors whose coverage situations are more varied — and who may need to navigate the ACA marketplace at various life transitions.
ACA Marketplace Carriers in Clay County
Clay County is part of the Jacksonville metro ACA rating area, giving residents access to a competitive set of carriers compared to rural North Florida counties.

Orange Park Medical Center (HCA Florida Orange Park Hospital) is Clay County's primary acute care facility. For specialist care, oncology, cardiac surgery, and pediatric services, Clay County residents use the full Jacksonville hospital system — UF Health Jacksonville, Mayo Clinic Florida, Baptist Medical Center, and Ascension St. Vincent's. When evaluating ACA plans, confirm in-network coverage at both Orange Park Medical Center and the Jacksonville facilities you're most likely to need.
Military Families and ACA Coverage in Clay County
The military dimension of Clay County's demographic profile creates specific health insurance questions. Active duty members and their enrolled dependents use TRICARE, which is considered qualifying coverage under the ACA. Veterans with VA healthcare coverage are also considered covered. These populations generally do not need ACA marketplace plans.
However, Clay County has a significant population of veterans who are not enrolled in VA healthcare, military spouses who work and may have separate coverage needs, and former service members who have transitioned out of the military and lost TRICARE eligibility. For all of these residents, the ACA marketplace is an important option. Transitions out of TRICARE typically trigger a Special Enrollment Period — meaning you don't have to wait for the November open enrollment window.
Florida's Coverage Gap — No Medicaid Expansion
Florida has not expanded Medicaid. Adults earning below 100% FPL ($15,960 single in 2026) do not qualify for Florida Medicaid or ACA subsidies. Clay County's suburban demographics mean most residents earn above this threshold, but lower-wage workers in retail, food service, and construction may still fall in the gap. If your income is at or below the FPL line, a licensed agent can help you understand all available options including community health centers.

Do military families at NAS Jacksonville use ACA marketplace plans?
Active duty members and their dependents use TRICARE, not ACA plans. Veterans with VA coverage are also considered covered. But separated servicemembers, military spouses without TRICARE, and veterans not enrolled in VA healthcare may use the ACA marketplace. Losing TRICARE coverage triggers a 60-day Special Enrollment Period.
Where do Clay County ACA plan members access hospital care?

What is the coverage gap and does it affect Clay County residents?
Florida has not expanded Medicaid. Adults below $15,960/year (single, 2026) fall in the coverage gap with no Medicaid and no ACA subsidy. Clay County's suburban profile means fewer residents are in this situation than in rural counties, but service and retail workers may still be affected.
