The San Patricio County medicare supplement market
San Patricio County posts one of the highest Medicare Advantage adoption rates in Texas — roughly 68% of its 14,672 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. UnitedHealthcare / AARP 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 15 Medicare Advantage plans are available in San Patricio County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).

What makes San Patricio County different: San Patricio County sits across Corpus Christi Bay in the Coastal Bend and has one of the highest Medicare Advantage penetration rates in Texas, around 64% of beneficiaries. Its economy is driven by petrochemical, steel and energy projects around Gregory-Portland (including the Steel Dynamics Sinton mill), and the county has lacked a full-service hospital since CARE Regional Medical Center in Aransas Pass closed after Hurricane Harvey.
