The Henderson County medicare supplement market
About 53% of Henderson County's 23,505 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. The county skews older than the Texas average (23% are 65 or older), which means heavy carrier competition and meaningful plan turnover each Annual Enrollment Period — a yearly review almost always pays off. 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 26 Medicare Advantage plans are available in Henderson County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).
