The Guadalupe County medicare supplement market
About 47% of Guadalupe County's 35,216 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. UnitedHealthcare / AARP Medicare Advantage 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 28 Medicare Advantage plans are available in Guadalupe County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).
