Express Scripts’ New 340B Rules Will Have Big Impact on Contract Pharmacy and Drug Reimbursement, Providers and Consultants Say

340B covered entities say they are deeply concerned about pharmacy benefit manager Express Scripts’ (ESI) requirements, effective Monday, governing what pharmacies in the PBM’s network must do when they identify that a previously submitted claim is 340B-eligible. Last night, ESI told 340B Report that the change is minor and that adequate notice has been provided to covered entities and their pharmacies. A number of covered entities disagree, however.
