The Nueces County medicare supplement market
Nueces County posts one of the highest Medicare Advantage adoption rates in Texas — roughly 65% of its 67,437 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. Humana Gold Plus H4007 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 25 Medicare Advantage plans are available in Nueces County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).
