Carey Appold

Vice President, Federal Medicaid Practice

Carey Appold has more than 17 years of experience working with health care and disability programs and policies, including Medicaid, the Basic Health Program (BHP), and the Ticket to Work program.

She came to Mathematica in 2014 from the Centers for Medicare & Medicaid Services (CMS), where she led the policy development, program design, implementation, and start-up for community-based long-term care initiatives, including the $400 million Ticket to Work program and $1.75 billion de-institutionalization initiative known as Money Follows the Person. In addition, she directed efforts to reform and structure Medicaid data to improve CMS’s capacity to manage the Medicaid and the Children’s Health Insurance Program. Most recently, Appold served as a technical expert on the BHP and as a long-term services and supports subject matter expert for CMS. Her work included developing regulations for eligibility, administration, and benefit design, and collaborating with states and stakeholders on design and implementation features.

Before joining CMS, Appold was a social science research analyst for the U.S. Health Care Financing Administration, a research associate for the Georgia Health Policy Center, and a policy assistant for the U.S. Senate Special Committee on Aging. She holds an M.P.H. in health policy and management from Emory University.
