Tennessee uses an actual-cost floor rather than a NADAC formula. Under Tenn. Code Ann. § 56-7-3206, a PBM may not reimburse a pharmacy less than its documented actual acquisition cost for the drug, may not fold the dispensing fee into that cost, and may not engage in spread pricing.
For lower-volume pharmacies, the PBM must pay a professional dispensing fee at least equal to the state Medicaid (TennCare) rate, separate from the drug cost. A pharmacy has 7 business days to appeal a below-cost payment, the PBM must resolve it within 7 business days, and a denied internal appeal can be escalated to the Department of Commerce and Insurance within 30 days.
