Pharmacy benefit managers; revise provisions related to.

HB 1119 (the "Representative Andy Stepp Pharmacy Benefit Prompt Pay Act") requires pharmacy benefit managers (PBMs) to reimburse pharmacies at least the National Average Drug Acquisition Cost (NADAC) for drugs plus a standard dispensing fee, ensuring pharmacies are paid fairly for medications. It prohibits PBMs from charging patients more than the amount retained by the pharmacy and bans PBMs from penalizing patients for choosing specific pharmacies or favoring certain pharmacies in networks. The bill also mandates clear appeal processes for pharmacies disputing low reimbursements and prohibits PBMs from retaliating against pharmacies for exercising rights under the law. These provisions directly affect PBMs, pharmacies, and patients in Mississippi by setting fair reimbursement standards and protecting patient choice.
