Who has Medicare in Jefferson County
Jefferson County is a smaller-city and town county; the U.S. Department of Agriculture describes it as: urban population of 5,000 to 20,000, adjacent to a metro area. Counties like this often sit between a metro area and rural communities, so some residents use hospitals and specialists in a neighboring county and a plan’s network across the county line matters.
CMS counts 8,054 Medicare beneficiaries in Jefferson County (2023). Their average age is 73, about the same as the Indiana average of 72. About 15% are “dual eligible,” meaning they have both Medicare and Medicaid, close to the state figure of 16%.
