The Zapata County medicare supplement market
Zapata County posts one of the highest Medicare Advantage adoption rates in Texas — roughly 75% of its 2,177 beneficiaries chose an MA plan over Original Medicare. That level of uptake usually means carriers compete hard locally, so the extra benefits (dental, OTC allowance, transportation, gym) tend to be richer than the Texas average. Only 14% of Zapata 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 11 Medicare Advantage plans are available in Zapata County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).

What makes Zapata County different: Zapata County has no hospital within its borders; residents rely on the Gateway Community Health Center clinic in the town of Zapata for primary care and travel to the critical-access Starr County Memorial Hospital in Rio Grande City or to acute-care hospitals in Laredo for inpatient and emergency services. The county skews younger than Texas overall (about 13.7% of residents are 65+), yet sits in a South Texas border region with very high Medicare Advantage uptake: per CMS, roughly 69% of Zapata County's ~2,100 Medicare beneficiaries are enrolled in Medicare Advantage in 2024, and neighboring Starr County reaches 81% MA enrollment, one of only three U.S. counties above 80% (KFF, 2024).
