Dodaro, Comptroller General of the United States and head of the U.S. Government Accountability Office (GAO), today announced the appointment of two new members to the Medicare Payment Advisory Commission (MedPAC), as well as the reappointment of four current members.

“Congress turns to MedPAC for insights and recommendations on Medicare policy issues,” Dodaro said. “I want to thank the many highly qualified candidates who expressed an interest in serving on the Commission this year. Today’s appointees bring impressive professional qualifications and experiences to the work of MedPAC.” 

The newly appointed members are Stacie B. Dusetzina, PhD, Associate Professor of Health Policy and an Ingram Associate Professor of Cancer Research at Vanderbilt University Medical Center in Nashville, TN, and Lynn Barr, MPH, Founder and Executive Chairwoman of Caravan Health in Kansas City, MO. Their terms began in May 2021 and will expire in April 2024.

The reappointed members, whose terms will also expire in April 2024, are Marjorie Ginsburg, MPH, Sacramento, CA; Jonathan Jaffery, MD, Professor of Medicine at the University of Wisconsin School of Medicine and Public Health in Madison, WI; Jonathan Perlin, MD, PhD, President of Clinical Services and Chief Medical Officer of HCA in Nashville, TN; and Jaewon Ryu, MD, President and Chief Executive Officer for Geisinger Health System in Danville, PA.

Congress established MedPAC in 1997 to analyze access to care, cost and quality of care, and other key issues affecting Medicare. MedPAC advises Congress on payments to providers in Medicare’s traditional fee-for-service programs and to health plans participating in the Medicare Advantage program. The Comptroller General is responsible for naming new Commission members.
