The Harris County medicare supplement market
Harris County posts one of the highest Medicare Advantage adoption rates in Texas — roughly 61% of its 639,500 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 12% of Harris 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. 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.
