Biloxi is Mississippi's entertainment capital and one of the Gulf Coast's most militarily significant cities — a combination that creates a health insurance landscape unlike any other in the region. The city's economy revolves around a strip of casino resorts stretching along Highway 90, one of the largest concentrations of gambling properties on the Gulf, and Keesler Air Force Base, home of the 81st Training Wing and the Air Force's primary technical training command. Understanding health insurance in Biloxi means navigating the intersection of hospitality workforce coverage, TRICARE military benefits, Mississippi's failure to expand Medicaid, and a relatively limited ACA marketplace carrier landscape.
This guide covers Harrison County's ACA marketplace options, the casino workforce's coverage situation, Keesler AFB TRICARE for military families, Mississippi's Medicaid coverage gap, and the local hospital systems that define the network landscape for Biloxi residents.
Biloxi's casino economy employs tens of thousands of workers across more than a dozen major properties. The largest resorts — Beau Rivage (operated by MGM Resorts), Hard Rock Hotel and Casino Biloxi, IP Casino Resort Spa, Golden Nugget Biloxi, and Scarlet Pearl Casino Resort — are substantial hospitality employers that offer group health benefits to qualifying full-time employees. A dealer, pit boss, or hotel manager working 40 hours per week at a major Biloxi resort will typically have access to employer-sponsored coverage.
The challenge lies with the large portion of the casino workforce that does not meet full-time thresholds. The ACA defines full-time as 30 or more hours per week on average, but many casino jobs are structured as part-time, split-shift, or on-call roles. Dealers working two or three shifts per week, banquet servers called in for special events, housekeeping staff working part-time during the week, and seasonal entertainment and events workers frequently fall below the threshold that triggers employer coverage obligations.
For these workers, the ACA marketplace is the primary path to coverage — but only for those earning at or above 100% of the federal poverty level. Mississippi's Medicaid non-expansion creates a floor problem for the lowest-wage casino and hospitality workers, discussed in the Medicaid Gap section below.
Keesler Air Force Base occupies a large footprint in Biloxi's east side and serves as the home of the 81st Training Wing, making it one of the Air Force's most important technical training installations. The 81st Medical Group at Keesler provides TRICARE Prime managed care for active duty personnel and their eligible family members. Active duty Keesler families receive comprehensive care through the on-base medical group and do not need ACA marketplace coverage.
The Biloxi VA Medical Center, located adjacent to Keesler, serves veterans throughout South Mississippi. VA healthcare is separate from TRICARE — eligible veterans receive care through the VA system, though they may also maintain other coverage simultaneously.
The civilian contractor community around Keesler is significant. Defense contractors, IT services firms, and specialized technical training companies support the 81st Training Wing's operations with large civilian workforces. Employees at larger defense prime contractors typically receive employer group health benefits. But employees at smaller subcontractors, consultants working on short-term task orders, and contractors in between assignments may need to use the ACA marketplace or COBRA continuation coverage from prior employer plans.
Military retirees under 65 in the Biloxi area typically use TRICARE Select, which functions as a PPO allowing the use of civilian providers with cost-sharing. TRICARE Select retirees should compare the cost and coverage of TRICARE Select against ACA marketplace options if they have a household member who is not TRICARE-eligible — mixing coverage types within a household is common in military retiree families.
Mississippi is one of a small number of states that has not expanded Medicaid under the ACA as of 2026. This policy decision creates a coverage gap that hits Biloxi's casino and hospitality workforce harder than almost any other industry in the state. The gap works as follows:
Coverage Gap Warning: If your household income is below 100% of the federal poverty level and you are a non-elderly adult without qualifying dependent children, you may fall into Mississippi's Medicaid gap. You are not eligible for ACA marketplace subsidies. Community health centers and federally qualified health centers (FQHCs) in Harrison County provide sliding-scale primary care for uninsured individuals in this situation.
The 100% FPL floor is a hard line — earning even one dollar above the poverty level unlocks eligibility for marketplace subsidies, while earning one dollar below excludes you from assistance entirely. For casino workers on hourly wages, tracking income carefully and understanding where you fall relative to the FPL is genuinely consequential.
Harrison County residents shopping on HealthCare.gov for 2026 ACA coverage will find the following carriers available:
Verify current plan availability by entering your Harrison County zip code at HealthCare.gov. Plan counts and carrier participation can shift between enrollment years. Open enrollment in Mississippi runs November 1 through January 15.
The primary civilian hospitals serving Biloxi and Harrison County are Merit Health Biloxi (formerly Biloxi Regional Medical Center), Garden Park Medical Center in Gulfport, and Singing River Hospital in Pascagoula — the latter serving the eastern Harrison County and Jackson County region. Keesler Medical Center on base provides care exclusively to TRICARE-eligible military personnel and is not available to civilian patients.
When comparing ACA marketplace plans, verify that your preferred hospital and primary care physician are in-network. In a market with three major carriers, one carrier may include a hospital that another excludes. Because the Singing River system is based in Pascagoula, its network status may vary by plan and carrier — particularly important for Biloxi residents who have established care relationships with Singing River-affiliated physicians.
