Pharmacy benefit managers and pharmacy services administrative organizations; provide certain regulations for.

HB 1123 prohibits "spread pricing" by pharmacy benefit managers (PBMs) and pharmacy services administrative organizations (PSAOs) in Mississippi, meaning they cannot charge more than the actual drug cost plus dispensing fees. It requires drug manufacturers to report wholesale acquisition costs to the Mississippi Board of Pharmacy quarterly and mandates PBMs/PSAOs to submit detailed pricing reports, ownership information, and anti-retaliation protections for pharmacists. The bill also authorizes the Board to publish pricing data online, conduct investigations, and impose monetary penalties for violations. This directly affects drug manufacturers, PBMs, PSAOs, and pharmacies by increasing transparency in drug pricing and limiting certain revenue practices.
