Although the Supreme Court has already weighed in on one case regarding states’ ability to regulate PBMs, the top law enforcement officials in more than 30 states are asking the high court to review another case that they claim will remove lingering uncertainty about the limits of states’ authority.
In PCMA v. Mulready, the current case, the Pharmaceutical Care Management Association is challenging an Oklahoma law — the Patient’s Right to Pharmacy Choice Act — which sets geography-based access standards for pharmacy networks. Among other provisions, it also bans PBMs from using discounts or cost-sharing differences to push plan members to certain in-network pharmacies, particularly those owned by that same PBM’s parent company.
