This publication provides an overview of how the Medicaid program is financed. It explains how the federal and state shares of funding are determined, briefly describes disproportionate share hospital payments and how those are affected by the Patient Protection and Affordable Care Act of 2010, and outlines financing mechanisms states have used to maximize federal Medicaid matching funds.
