Optimizing Patient Access to Medications: The American Dermatological Association’s Position Statement on Pharmacy Benefit Managers (PBMs) and Patient Access to Affordable and Appropriate Medications
Access to healthcare has been at the forefront of social and political debate for decades. Reliable and equitable access to provider prescribed medications is tantamount to the delivery of appropriate healthcare, and the lifecycle of medication manufacturing, distribution, pricing and procurement has been shrouded in an incomprehensible array of transactions and involved stakeholders. Among the middlemen interspersed between pharmaceutical manufacturers and patients are pharmacy benefit managers (PBM). Initially tasked with administering drug plans for health insurers,1 the role of PBMs has expanded over time. They currently function in a lightly regulated area,2,3 with few requirements for business transparency. Three PBMs, CVS Caremark, Optum RX, and Express Scripts, control distribution of nearly ¾ of the medications in the United States.
