NADAC — National Average Drug Acquisition Cost
The national average price pharmacies pay to acquire a drug, surveyed weekly per NDC from late 2013 to September 2026. Distinct from list price or what a plan pays, and a baseline for judging drug markups. The generic methodology changed in December 2024; do not trend across it silently.
