Minnesota runs two regimes. For commercial plans, chapter 62W requires MAC-pricing transparency and an appeal — a 15-business-day filing window, a 7-business-day PBM resolution, and a 1-business-day adjustment if upheld — but it sets no acquisition-cost reimbursement floor.
For Medicaid, a 2025 reform moves the program to a single PBM and sets a reimbursement floor at the lesser of NADAC or actual acquisition cost, plus the state Medicaid professional dispensing fee (about $11.55), beginning January 1, 2027, with an interim $4.50 directed dispensing payment for smaller pharmacies from July 1, 2025.
