Who has Medicare in Jefferson County
The U.S. Department of Agriculture classifies Jefferson County as a metro county (counties in metro areas of 250,000 to 1 million population). Counties like this tend to have a wider choice of hospitals and Medicare plans than rural ones, though networks still differ plan by plan.
CMS counts 46,869 Medicare beneficiaries in Jefferson County (2023). Their average age is 73, about the same as the Texas average of 73. About 14% are “dual eligible,” meaning they have both Medicare and Medicaid, higher than the state figure of 11%. Where many people have both, special plans for dual-eligible members can matter; see our Medicaid and dual eligible guide, since availability varies by plan and area.
Among people in Original Medicare in Jefferson County, CMS reported about 640 emergency room visits and 234 inpatient hospital stays per 1,000 beneficiaries in 2023, which is close to the state average for emergency visits (580) and close to it for hospital stays (226). About 11% received home health care. These figures describe how people use care under Original Medicare; they do not show what any plan covers or costs.
