The Austin County medicare supplement market
About 45% of Austin County's 7,864 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 18 Medicare Advantage plans are available in Austin County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).

What makes Austin County different: Austin County is a retiree-leaning rural county about 50 miles west-northwest of Houston where Bellville is the county seat (named for colonist Thomas B. Bell) and Sealy is the largest city. Its sole hospital, Mid Coast Medical Center-Bellville, traces to a small facility born of the 1920s Raccoon Bend oil boom and is now a locally operated acute-care hospital.
