Expanding Medicaid benefits can be a difficult intervention to achieve because of its potential high costs and the opposition of politicians and interest groups. Minimum Medicaid benefits are mandated by the federal government, but state agencies and legislatures have the ability to offer more generous benefits. The political climate and economic stability of a state have great impact on the ability of a state to expand its benefit offerings. However, generally, the infrastructure to offer these benefits and enroll individuals in the expanded benefits already exists in states.
