In Rutledge v. Pharmaceutical Care Mgt. Assoc., — U.S. –, 2020 WL 7250098 (Dec. 10, 2020), the Supreme Court held that ERISA’s broad express preemption will not reach a state law that focuses on the price of prescription drug benefits that a plan chooses to provide.
The particular question in Rutledge was whether ERISA preempted an Arkansas law regulating the price at which pharmacy benefit managers (PBMs) reimburse pharmacies for the cost of drugs covered by ERISA prescription drug plans. The Court described PBMs as
a little-known but important part of the process by which many Americans get their prescription drugs. Generally speaking, PBMs serve as intermediaries between prescription-drug plans and the pharmacies that beneficiaries use. When a beneficiary of a prescription-drug plan goes to a pharmacy to fill a prescription, the pharmacy checks with a PBM to determine that person’s coverage and copayment information. After the beneficiary leaves with his or her prescription, the PBM reimburses the pharmacy for the prescription, less the amount of the beneficiary’s copayment. The prescription-drug plan, in turn, reimburses the PBM.
