Summary: written with AI from the case record.

What it's about
The law regulates how pharmacy benefit managers (PBMs) reimburse pharmacies for prescription drugs, and the Pharmaceutical Care Management Association challenged it.
The case was part of a broader conflict between federal employee-benefit rules and similar pharmacy-reimbursement laws in many states.
Question presented
Whether the Eighth Circuit erred in holding that Arkansas's statute regulating PBMs' drug-reimbursement rates, which is similar to laws enacted by a substantial majority of States, is preempted by ERISA, in contravention of this Court's precedent that ERISA does not preempt rate regulation.
What the Court decided
Holding
Arkansas’ Act 900 is not pre-empted by ERISA. 891 F. 3d 1109, reversed and remanded.

- Reversed
The vote
What's next
