The Role of Pharmacy Benefit Managers in Access to Biologics for Dermatologic Conditions

In this commentary, we discuss the role of pharmacy benefit managers (PBMs) on access to biologics for patients with psoriasis. We highlight structural and system level barriers to biologics access, as well as how PBMs work as intermediaries between insurers, pharmacies, and drug manufactures to influence prescription formularies and generate health savings. We also discuss how controversial PBM practices such as step therapy, prior authorizations, and spread pricing may limit access to biologics and potentially increase cost for patients. Finally, we highlight how dermatologists and national organizations such as the National Psoriasis Foundation can collaborate and advocate for legislative reforms to increase transparency among PBMs.
