Medicaid and CHIP Projects
Medicaid and the Children's Health Insurance ProgramMathematica works closely with states, federal agencies, and foundations to help design, evaluate, and improve Medicaid and state Children’s Health Insurance Programs (CHIP). The questions we address include:
Mathematica has been at the forefront of evaluating how states have designed and implemented their CHIP programs, identifying lessons from that experience for both states and federal agencies. We have also worked with states and coalitions of public and private partners in a multi-year foundation-supported initiative to find effective ways of enrolling more children and their families in Medicaid and CHIP. As states and the federal government consider the future of Medicaid and CHIP in health care reform, these experiences with the design and implementation of coverage expansions can help inform future decision making.

Mathematica is working with the Centers for Medicare & Medicaid Services (CMS) to evaluate a major initiative―Money Follows the Person (MFP)―aimed at helping state Medicaid programs reduce their reliance on institutional care for people needing long-term care, and expand options for receiving care in the community. Also for CMS, we are identifying ways to improve the identification of Medicaid home- and community-based services in Medicaid Analytic eXtract (MAX) data files so that both states and the federal government can get a better understanding of the nature, scope, and cost of these services. MAX files can also be used for detailed studies of nursing facility residents and their care.

For more than a decade, Mathematica has worked with the Center for Health Care Strategies (CHCS) and individual states to help design, implement, and improve Medicaid managed care programs, with a focus on programs aimed at people with chronic illnesses and disabilities. We have also recently started working with the Medicaid and CHIP Payment and Access Commission (MACPAC) to provide analysis and guidance on developing a research agenda on Medicaid managed care.
Mathematica is committed to conducting research that contributes to quality improvements in the care provided to those with mental health needs and substance abuse problems. We are working with the Office of the Assistant Secretary for Planning and Evaluation at the U.S. Department of Health and Human Services to analyze how to increase the implementation in Medicaid of evidence-based practices in treating schizophrenia and bipolar disorder. We worked with the Substance Abuse and Mental Health Services Administration to reduce recidivism of those with serious mental illnesses by facilitating maintenance of Medicaid eligibility upon release from institutions.

Mathematica is working with CMS and states to evaluate two major federal-state programs aimed at helping workers with disabilities obtain health benefits and supports they need to remain in the workforce and maintain their independence.

Mathematica researchers have been working with CMS since 2002 on state-by-state and national tables and chartbooks that show Medicaid drug use and expenditures by beneficiary characteristics (age, sex, and race), basis of eligibility (children, adults, disabled, aged), and type of drug (brand versus generic, top 10 drug groups, 17 therapeutic categories, and drugs excluded by statute from Medicare Part D). There are separate sets of tables for dual eligibles and nonduals. Tables and chartbooks for 1999 and 2001-2006 are on the CMS or Mathematica websites, and tables and a chartbook for 2007 are being prepared.

For more than two decades, Mathematica researchers and analysts have worked with CMS and states to improve the value and usability of the Medicaid claims and eligibility data that all states are required to submit electronically to CMS through the Medicaid Statistical Information System (MSIS). We help CMS convert these data into MAX files that link demographic and eligibility information for all beneficiaries to summaries of their service use and costs by date of service. These person-level summary files can be linked to more detailed files on beneficiaries’ inpatient hospital, long-term-care, pharmacy, physician, and other service use. Mathematica has used these files in reports, chartbooks, issue briefs, and journal articles to analyze Medicaid enrollment, service use, and costs among Medicaid enrollees receiving prescription drugs, behavioral health services, and long-term care. Mathematica is currently helping CMS expand and enhance the Medicaid data infrastructure to support comparative effectiveness research (CER). Mathematica is also providing technical assistance to states to improve the reporting of states’ separate CHIP data and managed care encounter data.

Mathematica researchers and analysts work on the front lines of health care research, and the results of our work is frequently used to inform public policy decisions. The following reports represent Mathematica’s impact on the health care reform debate and implementation strategy as it relates to Medicaid and CHIP. Related publications:
