Protecting Patients Against PBM Abuses Act

This bill regulates pharmacy benefit managers (PBMs) working with Medicare Part D prescription drug plans. It prohibits PBMs from earning income based on drug prices or rebates (requiring flat fees instead), mandates equal reimbursement for all network pharmacies, and requires PBMs to report how much of drug rebates they pass through to Medicare plans. The law also mandates annual compliance certifications and requires the government to publish aggregated transparency data (without revealing specific plan details) starting in 2024. These changes directly affect Medicare Part D plans and the seniors who rely on them for prescription drug coverage.
