A primary aim of the Patient Protection and Affordable Care Act (ACA) is to expand insurance coverage, especially among households with lower incomes. The Congressional Budget Office (CBO) projects that about one-third of the additional insurance coverage expected to occur because of the law will come from expansion of the existing, unreformed Medicaid program. The rest of the coverage expansion will come from enrolling millions of people into subsidized insurance offerings on the ACA exchanges — offerings that have strong similarities to Medicaid insurance.
