WASHINGTON (May 22, 2026) - Orice W. Brown, Acting Comptroller General of the United States and head of the U.S. Government Accountability Office (GAO), today announced the appointment of the Chair, Vice Chair, and two new members to the Medicare Payment Advisory Commission (MedPAC). She also reappointed two current members. MedPAC advises Congress on payments to providers in Medicare's traditional fee-for-service program and to health plans participating in the Medicare Advantage program.

"For nearly three decades, MedPAC has served as an independent, nonpartisan advisory body for Congress covering the full range of critical issues facing the Medicare program," Brown said. "I am confident that the new leadership, in collaboration with commission members and staff, will continue to support congressional deliberations with robust, evidence-based information and recommendations."

Congress established MedPAC in 1997 to analyze access to care, cost and quality of care, and other key issues affecting Medicare. The Comptroller General is responsible for naming the Chair, Vice Chair, and new commission members. GAO takes a deliberate approach to appointments to health care advisory bodies, including extensive vetting of candidates, candidate interviews, and outreach to cognizant congressional committees to understand their priorities and needs. Appointments reflect the broad range of expertise and perspectives as required by law.

Brown is appointing Amol Navathe, MD, PhD, as the Chair of MedPAC. His term will expire in April 2029. She is also appointing Gregory Poulsen, MBA, Senior Vice President for Intermountain Health, as Vice Chair. Poulsen's term as Vice Chair will expire in 2028.

The newly appointed members are Benedic Ippolito, PhD, and Danielle Pierotti, PhD, RN. Their terms will expire in April 2029. The reappointed members are Tamara Konetzka, PhD, and Brian Miller, MD, MBA, MPH. Their terms will expire in April 2029.
