The Brewster County medicare advantage market

At roughly 39% MA penetration, most of Brewster County's 2,368 Medicare beneficiaries stay on Original Medicare, frequently paired with a Medigap policy. That pattern usually signals retirees here prize provider choice and predictable out-of-pocket costs over the lower premiums of MA. The county skews older than the Texas average (25% are 65 or older), which means heavy carrier competition and meaningful plan turnover each Annual Enrollment Period — a yearly review almost always pays off. UnitedHealth Group, Inc. 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 6 Medicare Advantage plans are available in Brewster County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).
