ERISA broadly preempts state laws that “relate to” ERISA-governed employee benefit plans to ensure a uniform federal regulatory scheme and to relieve ERISA plans from the burdens of satisfying a patchwork of state laws. Recently, however, several states have enacted legislation designed to regulate the prices that pharmacy benefit managers, as third-party administrators for ERISA-governed plans, agree to reimburse pharmacies for dispensing prescription drugs to ERISA plan members. These regulations run afoul of ERISA, as the US Court of Appeals for the Eighth Circuit has twice held.
