State attorneys general in Florida and Louisiana have filed lawsuits against pharmacy benefit managers alleging collusion and price-fixing of reimbursement rates paid to retail and independent pharmacies. These cases represent a growing trend of states pursuing antitrust enforcement actions against PBMs for allegedly coordinating to suppress pharmacy reimbursements.

Florida

On August 27, 2026, the Florida Office of the Attorney General filed a lawsuit against two PBMs for allegedly colluding in December 2019 to fix the price of reimbursement rates provided to Florida retail pharmacies.

(ESI) and Prime Therapeutics LLC engaged in illegal price-fixing resulting in below-cost reimbursements provided by ESI and Prime to independent pharmacies in Florida.
