Virginia regulates PBMs through MAC transparency and anti-self-dealing parity rather than a drug-cost floor, and only for fully-insured commercial plans. A pharmacy may dispute a MAC within 14 days of adjudication, and a PBM may not pay a pharmacy less than it pays its own affiliate for the same pharmacist services.
These protections expressly exclude self-funded ERISA plans, Medicaid, and Medicare Part D, and they do not tie reimbursement to NADAC or acquisition cost. A 2026 law tightens other PBM conduct but still adds no commercial floor.
