There is no telling what this number would be without PBMs. PBMs seek to control that spending while providing the most effective care to their members. These negotiation skills have the potential to provide significant value. There is nothing more a CEO from a drugmaker would love than to remove PBMs from the negotiating table. Point-of-sale rebates, for example, might reduce member cost share but any lost revenue, by non-fiduciary PBMs or health plans, will be shifted elsewhere. A CBO (Congressional Budget Office) report happens to agree. Reducing PBM purchasing power (negotiating rebates) would allow pharmaceutical companies to offer discounts 15% smaller than their current rebates. There are a few additional ways in which PBMs can help their clients (see figure 1):

1) Administer and process claims
2) Provide pharmacy networks
3) Provide mail order services
4) Negotiate with manufacturers
5) Optimize plan performance of clients
6) Ensure safe, cost-effective, appropriate medication utilization
