Union County is one of Florida's smallest and most distinctive counties. It sits in North Florida between Gainesville and Jacksonville, along a quiet stretch of US-90 in the Suwannee River region. The county's reported population of approximately 15,000 includes a large incarcerated population housed at Union Correctional Institution and Florida State Prison — two of the largest correctional facilities in Florida's state prison system. The civilian population is closer to 8,000 people.
Understanding health insurance in Union County requires understanding its economy. State correctional employment dominates — and state employees receive government health benefits, not ACA marketplace coverage. But the county's civilian non-state-employee population does use the ACA marketplace, and their options, subsidies, and challenges are the same as any other small rural Florida county.
Correctional officers, support staff, and other state government employees at Union CI and Florida State Prison receive health coverage through the Florida State Group Insurance Program (FSGJP), administered by the Florida Department of Management Services. This is a group benefits program entirely separate from the ACA marketplace — state employees do not enroll through HealthCare.gov and are generally not eligible for ACA marketplace subsidies while enrolled in state coverage.
State employee health plans typically offer a range of options — including HMO-style and PPO-style plans — at premiums significantly subsidized by the State of Florida. State employees who are enrolled in affordable state coverage are not eligible for ACA marketplace subsidies; however, their dependents who are not covered under the state plan may be eligible for marketplace coverage under certain circumstances. A licensed agent can help evaluate these family coverage situations.
Despite the dominance of state employment, a civilian population does rely on the ACA marketplace:
Self-employed contractors and service providers: Individuals who provide transportation, food service, equipment maintenance, construction, or other services to the prison system on a contract basis, rather than as direct state employees, are typically self-employed and must secure their own coverage.
Agricultural operators: Union County has some agricultural land and farming families who are self-employed and need individual coverage through the marketplace.
Retail, service, and small business workers: The small business community in Lake Butler — restaurants, hardware stores, gas stations, and other local businesses — employs workers who may not receive employer coverage and need marketplace plans.
Part-time and non-benefited state workers: Some state facility support roles may not qualify for full state employee benefits, leaving these individuals to find individual coverage.

Union County has no hospital within its borders. The nearest significant hospital is Shands Lake Shore Regional Medical Center in Lake City (Columbia County), approximately 20–25 miles north. For advanced specialty care — oncology, cardiac surgery, complex neurology — residents travel to UF Health Shands in Gainesville (approximately 40 miles south) or to Jacksonville hospitals (approximately 60 miles northeast). Telemedicine is increasingly important for Union County residents to access specialist consultations without extensive travel. Verify that Lake City and Gainesville facilities are in-network for any plan before enrolling.
