The Madison County medicare advantage market
About 54% of Madison County's 2,711 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 14 Medicare Advantage plans are available in Madison County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).

What makes Madison County different: Madison County's share of residents age 65+ is only about 15.5%, unusually low for a rural Texas county, because the Texas Department of Criminal Justice's Jim Ferguson Unit prison near Midway (capacity ~2,417 inmates) inflates the county's working-age population; even so, Medicare Advantage penetration is high at roughly 52%, with Humana and UnitedHealthcare the dominant carriers.
