GAO Makes PTAC Appointments

WASHINGTON, DC (October 18, 2021) – Gene L. Dodaro, Comptroller General of the United States and head of the U.S. Government Accountability Office (GAO), today announced the appointment of three new members to the Physician-Focused Payment Model Technical Advisory Committee (PTAC).

“Congress directed the Department of Health and Human Services to shift Medicare from a program that pays based on volume to one that pays based on value. As part of this effort, PTAC can play an important role,” Dodaro said. “After reviewing this latest round of extremely well-qualified candidates, I am pleased to share our 2021 selections for the committee.”

The newly appointed members are Lawrence R. Kosinski, MD, MBA, AGAF, FACG; and Soujanya (Chinni) Pulluru, MD. Their terms will expire in 2024. In addition, Walter Lin, MD, MS, MBA was newly appointed to serve out the remaining term of the recently resigned Carrie Colla, PhD, which will expire in 2023. Current members Angelo Sinopoli, MD and Jennifer L. Wiler, MD, MBA have been reappointed, and their terms will expire in 2024.

Congress established PTAC in 2015 to provide comments and recommendations to the Secretary of Health and Human Services on physician payment models. The Comptroller General is responsible for appointing members to the committee.
