Senators Thom Tillis (R-Cornelius, NC) Catherine Cortez Masto (D-NV), Ron Wyden (D-OR), and Mike Crapo (R-ID) recently introduced bipartisan legislation to ensure seniors with Medicare get the best possible deal on their prescription drug coverage. The Medicare PBM Accountability Act would require pharmacy benefit managers to disclose behind-the-scenes practices that drive up prices and costs for the nearly 50 million Americans enrolled in Medicare Part D drug plans.
