The Hays County medicare advantage market
About 50% of Hays County's 42,361 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. Only 13% of Hays residents are 65 or older, so it's a younger county where fewer agents specialize in Medicare locally — exactly the gap a dedicated Texas agent fills. UnitedHealthcare 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 Hays County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).
