The Santa Rosa County medicare supplement market
About 46% of Santa Rosa County's 44,620 Medicare beneficiaries are in Medicare Advantage — right around the national norm — so you'll find a genuine mix of competitive MA plans and Medigap options here rather than a one-sided market. Humana currently leads the county by enrollment, but the lowest total-cost plan for your specific drugs and doctors is often a smaller carrier — which is why we run all of them side by side instead of pushing the biggest name. Right now roughly 23 Medicare Advantage plans are available in Santa Rosa County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).

What makes Santa Rosa County different: Santa Rosa County is anchored by Naval Air Station Whiting Field near Milton, one of the Navy's two primary fixed- and rotary-wing pilot-training bases, giving the county a large active-duty, veteran and military-retiree population. It is one of Florida's faster-growing counties, with the Navarre area its largest community; its 65-plus share (about 17.5%) sits well below Florida's 21.8% because of the working-age military presence.
