90 Percent and the Power of US Pharmacy Benefit Managers

You stand at the pharmacy counter, facing a price tag that seems to defy logic. Between the manufacturer's laboratory and your medicine cabinet lies a complex financial architecture that few patients ever see. In this investigation, Economics Made Weird explores the rise of US pharmacy benefit managers—the specialized intermediaries hired by health plans to control costs, who now sit at the center of a multi-billion dollar friction point. The Federal Trade Commission recently reported that the six largest PBMs now handle more than 90 percent of all prescriptions in the United States. This concentration has transformed these entities from simple administrative clerks into the ultimate gatekeepers of the American healthcare system. Through the control of formularies, the negotiation of secretive rebates, and the practice of spread pricing, PBMs influence which medicines are accessible and how much they cost. We trace the evolution of the PBM from a 1960s paperwork solution to a vertically integrated powerhouse. Why do health plans continue to rely on them? How does a rebate actually affect the list price of life-saving medication? And what happens to independent pharmacies when their primary reimbursement source is also their direct competitor? While the Government Accountability Office documents the essential cost-control functions these intermediaries perform, the FTC’s interim staff report raises critical questions about market power and misaligned incentives. It is important to note, as the FTC does, that these findings include staff analysis and qualified language; this market structure does not mean every PBM contract increases every patient's price. However, the systemic influence of these middlemen is undeniable. We examine the mechanics of a system where the entity hired to lower costs may have a financial interest in the complexity of the price.
