This bill requires pharmacy benefits managers (PBMs) to notify health carriers and pharmacies of any potential conflict of interest, including but not limited to common ownership or any other relationship between the PBM and any other health carrier or pharmacy with which the PBM contracts (Section 376.387.5, RSMo). The bill specifies that no PBM shall prohibit, penalize, or restrict health carriers or enrollees from obtaining drugs from pharmacies that are not under contract with the PBM (Section 376.388.5).
