Daniel Tsai, Deputy Administrator and Director


Daniel Tsai is the Deputy Administrator and Director of the Center for Medicaid and CHIP Services (CMCS). Daniel comes from the Commonwealth of Massachusetts where he served as the Assistant Secretary for MassHealth and Medicaid Director. His tenure has focused on building a robust and sustainable Medicaid program that ensures equitable coverage and reshapes how health care is delivered for two million individuals and families in the state.

Daniel has helped lead Massachusetts Medicaid through its most significant restructuring since the 1990s through its landmark 2016 Medicaid 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. In addition, during his tenure, the agency has made critical investments in strengthening community health centers, behavioral health, and home and community-based services.

Having worked closely with organizations across almost every aspect of health care, including a diverse range of Medicaid programs and provider organizations, Daniel brings extensive experience across Medicaid, Medicare, and working with stakeholders to design and implement innovative models for health care coverage, delivery and payment.

Daniel earned a Bachelor of Arts in Applied Mathematics and Economics from Harvard University, summa cum laude.
