In a case being followed closely by many in the pharmacy industry, Rutledge v. Pharmaceutical Care Management Association, the Justices issued a decision in Arkansas law that prohibits PBMs from reimbursing pharmacies at a lower rate than what the pharmacies pay to fill prescriptions. This confirms that that law, and by extension several similar laws being passed nationwide, is not preempted by the Employee Retirement Income Security Act,or ERISA, of 1974.
