Subsequently, other pharmacy benefit managers followed suit, and today it is a widely accepted management practice. In 2017, clients who adopted our managed formulary approach actually had negative drug price growth; whereas those who had more “open” formularies and opted out of drug removals saw price growth of 2.6 percent. Moreover, those with managed formularies saw improved utilization; drug affordability helped more plan members stay adherent to their prescribed medications.

Not surprisingly, trend for clients with managed formularies was also lower. Through 2018, our managed formulary strategy is expected to deliver $13.4 billion in cumulative savings to pharmacy benefit management clients, through drug removals, inclusion of lower-cost brands and transition to generics.*
As the pharmaceutical market continues to evolve, it’s necessary to evolve formulary management strategies as well. Since 2012, we have also introduced new-to-market drug evaluations, which help to provide control from day one for newly launched medications. We were also the first to evalutate biosimilars for preferred formulary placement when they are the most cost-effective option. More recently, we launched indication-based formularies in which a drug with multiple uses may be preferred for one indication, such as rheumatoid arthritis, but not for another such as psoriasis. Determinations of preferred status are based on clinical effectiveness.
Plans are often very deliberate about their approach to formulary, and rightly so. Formulary is the foundation of a drug cost management strategy and is also a significant determinant of member cost. Formulary changes may be disruptive to some members leading to concerns about therapy drop-offs. For these reasons, CVS Health manages formulary transitions carefully, relying on predictive modeling to identify those members likely to benefit from extra support, and we tailor communication strategies to help them make a smooth transition.
