North Dakota has a strong MAC-transparency and PBM-licensure regime but not a reimbursement floor. Under N.D.C.C. § 19-02.1-14.2, a PBM may not set MAC prices below its own pricing sources and may not fold dispensing fees into the MAC calculation, and it must answer a MAC appeal within 7 business days, applied to all similarly situated network pharmacies. The MAC rules do not apply to the state Medicaid program.
The 2025 PBM licensure overhaul (HB 1584), enacted as an emergency measure, adds licensing and enforcement but does not create an acquisition-cost or NADAC floor.
