Stuart is the county seat of Martin County and the cultural and commercial center of Florida's Treasure Coast. Known nationally as the "Sailfish Capital of the World," Stuart blends a charming historic downtown with a waterfront lifestyle that attracts both permanent residents and seasonal visitors. The city's population of approximately 17,000 is part of a broader Martin County community of about 165,000, and the health insurance landscape here reflects the Treasure Coast's mix of retirees, small-business owners, and working families.
For Stuart residents without employer-sponsored health insurance — whether retired early, self-employed, or between jobs — the ACA marketplace provides the primary pathway to comprehensive coverage. Martin County's rating area includes competitive carrier options, and the presence of Cleveland Clinic Martin Health gives Stuart residents access to a nationally recognized healthcare system. Understanding how to navigate plan selection, subsidy eligibility, and provider networks can save Stuart residents thousands of dollars annually.

Stuart's healthcare landscape is anchored by Cleveland Clinic Martin Health, a system that joined the Cleveland Clinic network and now operates as a regional affiliate of one of the nation's top-ranked hospital systems. Cleveland Clinic Martin North Hospital, located in Stuart, provides emergency services, surgical care, cardiac services, and a range of specialty programs. Cleveland Clinic Martin South Hospital serves the southern portion of Martin County.
The Cleveland Clinic affiliation is significant for ACA plan selection. Stuart residents should verify that Cleveland Clinic Martin Health is included in any marketplace plan they consider. Both Florida Blue and Ambetter plans serving Martin County generally include Martin Health facilities, but individual physician participation can differ between carriers. A licensed agent can confirm network status for your specific doctors before you enroll.
Health insurance in Stuart
Martin County's ACA marketplace in 2026 includes Florida Blue and Ambetter from Sunshine Health as the primary carriers. Florida Blue offers both PPO and HMO plan types. PPO plans provide greater flexibility — the ability to see specialists without referrals and to access out-of-network providers at a higher cost share — which is valuable for Stuart residents who travel seasonally or who prefer maximum choice. Ambetter HMO plans are typically more affordable on monthly premium and can be an excellent value for residents who receive all their care locally within Martin County.
For Stuart's retiree population, Florida Blue PPO plans are often the preferred choice because of their broader network access and out-of-network provisions. For younger families and working adults focused on minimizing monthly costs, Ambetter's lower-premium HMO options may be more appropriate — especially when combined with substantial ACA subsidies that bring net costs down significantly.
ACA premium tax credits are available to Stuart residents based on modified adjusted gross income (MAGI) and household size. A single adult earning between $15,960 and $60,240 (100% to 400% of the federal poverty level) qualifies for premium tax credits that reduce monthly costs. The most generous subsidies apply below 200% FPL ($31,920 for a single adult), where monthly Silver plan premiums can drop to $0 to $80 per month and Cost-Sharing Reductions dramatically reduce deductibles and out-of-pocket maximums.
Even above 400% FPL, the American Rescue Plan's 8.5% income cap rule ensures that no household pays more than 8.5% of MAGI toward the benchmark Silver plan premium. For Stuart retirees managing investment income and retirement account withdrawals, strategic income timing can optimize subsidy eligibility while maintaining the lifestyle they expect on the Treasure Coast.
Martin County's ACA premiums reflect Treasure Coast market rates. A benchmark Silver plan for a 40-year-old in Stuart runs approximately $470 to $510 per month before subsidies in 2026.

| $45,181 – $60,240 | 300–400% | Moderate subsidy | $185 – $315/month |
| Above $60,240 | 400%+ | May qualify if premium > 8.5% of income | Varies — 8.5% income cap applies |
