Kaiser Commission on Medicaid and the Uninsured: “As care delivery and financing models in Medicaid have multiplied, so has the terminology used to refer to them. This glossary seeks to clarify and define the terms that are widely used to describe the diverse approaches that states are taking to reform the way they organize and pay for care for Medicaid beneficiaries. Although some terms are also used in other contexts, including private insurance and Medicare, this glossary confines itself to how they tend to be applied in the context of Medicaid.”
