Medicaid and CHIP

Medicaid and the Children’s Health Insurance Program (CHIP) currently serve more than 72 million children, pregnant women, adults, and people with disabilities. Administered by the state under federal requirements and jointly funded by both levels of government, these programs form the backbone of the safety net system in the United States.
As state-administered programs, Medicaid and CHIP serve as incubators for system transformation and are testing new ways to deliver and pay for care, particularly for individuals with chronic illnesses and disabilities, with mental health and substance abuse needs, or who are dually eligible for Medicaid and Medicare. Mathematica works closely with states and federal agencies, foundations, and private-sector stakeholders—such as Managed Care Organizations—to help design and evaluate new initiatives, provide implementation technical assistance, measure quality, support advanced data analytics, and otherwise improve Medicaid and CHIP. Well-versed in program history and goals, our teams bring decades of experience to understand and translate complex state and national findings, to chart the path to progress.
