The Shelby County medicare supplement market
About 54% of Shelby County's 5,417 Medicare beneficiaries are in Medicare Advantage — right around the national norm — so you'll find a genuine mix of competitive MA plans and Medigap options here rather than a one-sided market. 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 11 Medicare Advantage plans are available in Shelby County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).

What makes Shelby County different: Shelby County has had no acute-care inpatient hospital within its borders since the 54-bed Shelby Regional Medical Center in Center closed in 2013 after CMS terminated its Medicare/Medicaid certification; residents now rely on a freestanding 24/7 ER in Center (opened 2014, operated by Nacogdoches Medical Center) and must drive roughly 30 miles to Nacogdoches for hospital admission. Despite this rural setting, Medicare Advantage penetration is unusually high at about 52% of beneficiaries (2,761 of 5,364 in 2024), well above the rate of many comparable East Texas timber-and-poultry counties.
