Who has Medicare in Sumter County
Sumter County sits in a metro area, which the USDA defines as counties in metro areas of fewer than 250,000 population. That usually means more doctors, more hospitals and more plan choices in the area.
CMS counts 24,407 Medicare beneficiaries in Sumter County (2023). Their average age is 73, about the same as the South Carolina average of 73. About 10% are “dual eligible,” meaning they have both Medicare and Medicaid, higher than the state figure of 7%. 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 Sumter County, CMS reported about 575 emergency room visits and 227 inpatient hospital stays per 1,000 beneficiaries in 2023, which is close to the state average for emergency visits (563) and higher than it for hospital stays (202). About 10% received home health care. These figures describe how people use care under Original Medicare; they do not show what any plan covers or costs.
