Pharmacy Benefit Managers

Pharmacy benefit managers (PBMs) in the US manage prescription drug programs for various health plans, including Medicare and Medicaid. PBMs negotiate prices with drug manufacturers and pharmacies, process claims, and provide mail-order services, but have been criticized for unfair business practices and lack of transparency in their pricing methods. The three largest PBMs control around 80% of the market share, and their consolidation has led to lawsuits and bipartisan criticism, with several states creating regulations to address these issues.learn more on wikipedia
