Medicaid covers all of the following groups, EXCEPT

a. People with low incomes
b. Single working individuals with above-average incomes
c. Individuals with disabilities
d. Blind people

Single working individuals with above-average incomes

Rationale: Medicaid does not cover single working individuals with above-average incomes. It does cover individuals earning less than a specified yearly income, individuals with disabilities, blind people, and children whose parents receive Medicaid.
