The Kaiser Commission on Medicaid and the Uninsured reported that there is significant variation across states in the percentage of dually eligible individuals enrolled in Medicaid. "Dual eligibles" are individuals who are eligible for both Medicaid and Medicare benefits and account for more than 9 million persons enrolled in these programs.
Kaiser found that dual eligibles account for a varying share of Medicaid enrollees by state, ranging from 10 percent up to 26 percent. The report also breaks down data by county, finding significant variation even within a state.
Detailed data on the state and county level is also available in the report.
