Vermont’s PBM law (18 V.S.A. § 3631, from Act 127 of 2024, effective July 1, 2024) combines MAC transparency, a MAC appeal, anti-self-dealing parity, and a spread-pricing ban — but stops short of a drug-cost floor. A PBM may not pay an in-state pharmacy less than it pays its own affiliate for the same pharmacist services.
Pharmacies can appeal a MAC within 10 calendar days of adjudication, with a 10-day response window and a MAC update if the appeal succeeds. None of these provisions guarantee reimbursement at or above NADAC or acquisition cost.
