Tsai is the deputy administrator and director of Center for Medicaid and CHIP Services (CMCS) at the Centers for Medicare & Medicaid Services (CMS). He leads CMCS in addressing disparities in health equity and serving the needs of individuals and families who rely on these essential programs.
He previously was assistant secretary for MassHealth and Medicaid director for the Commonwealth of Massachusetts. His tenure focused on building a robust and sustainable Medicaid program to ensure equitable coverage and improve how health care is delivered for 2 million people.
Tsai also helped lead Massachusetts’ Medicaid program through its most significant restructuring since the 1990s and its landmark 2016 Medicaid Section 1115 waiver. Under these reforms, MassHealth implemented one of the most at-scale shifts to value-based care in the nation. Through the waiver, MassHealth also launched a unique program committing significant investments for nutritional and housing supports to address the social determinants of health for high-cost, at-risk individuals.
Having worked closely with organizations across almost every aspect of health care, Tsai brings extensive experience across Medicaid and Medicare. He has worked with stakeholders to design and implement innovative models for health care coverage, delivery, and payment. Tsai holds a bachelor’s degree, summa cum laude, in applied mathematics and economics from Harvard University.
