Closing The Medicaid Coverage Gap: Options For Reform.

Eight years after the US Supreme Court's landmark decision in National Federation of Independent Business v. Sebelius, more than two million of the nation's poorest working-age adults continue to feel its effects. These are the people who, because of the decision, remain without a pathway to affordable health insurance coverage because they live in a state that has not expanded Medicaid under the Affordable Care Act (ACA). Closing the coverage gap created by NFIB v. Sebelius represents the ACA's most pressing piece of unfinished business. Several options, which vary in cost and political complexity, exist for closing the gap in ways that respect the ACA's pluralistic approach to insurance coverage while adhering to constitutional principles. These considerations must be balanced against the urgency of the problem and the fact that, constitutionally speaking, Medicaid alone can no longer guarantee a national remedy to the fundamental issue of health insurance inequality for the poorest Americans.
