Summary
Pharmacy Benefit Managers (PBMs) are third-party administrators of prescription drug programs in the United States, serving a wide range of health plans and government programs. They act as crucial intermediaries in the pharmaceutical supply chain, managing formularies, maintaining pharmacy networks, processing claims, and negotiating prices and rebates between pharmacies, drug manufacturers, wholesalers, and health insurance companies. As of 2023, PBMs managed benefits for 275 million Americans, with the three largest PBMs—CVS Caremark, Cigna Express Scripts, and UnitedHealth Group’s Optum Rx—dominating approximately 80% of the market share, which was valued at nearly $600 billion in 2024. This significant market concentration has led to widespread criticism and lawsuits, with sources like The New York Times, the Federal Trade Commission, and state attorneys general accusing PBMs of unfair business practices and unfairly raising drug prices in 2024. In response, several states have implemented regulations, and their role is a key point of discussion in efforts to lower drug prices, including in the context of executive orders on pharma benefits and the competitive landscape with China's pharmaceutical industry.

The role of pharmacy benefit managers includes managing formularies, maintaining a pharmacy network, setting up rebate payments to pharmacies, processing prescription drug claims, providing mail order services, and managing drug use. PBMs play a role as the middlemen between pharmacies, drug manufacturers, wholesalers, and health insurance plan companies.
