What Does NADAC Stand For?
NADAC stands for National Average Drug Acquisition Cost. It is a pricing benchmark published by the Centers for Medicare & Medicaid Services (CMS) that reflects the average price pharmacies pay to acquire prescription drugs from wholesalers and manufacturers.
Unlike other pricing benchmarks, NADAC is based on actual invoice prices reported by pharmacies across the United States, making it one of the most accurate representations of real-world drug costs.
How NADAC Pricing Is Calculated
NADAC pricing is calculated through a voluntary survey of retail community pharmacies conducted by Myers and Stauffer LC on behalf of CMS. The process involves:
- Weekly surveys sent to a random sample of pharmacies
- Collection of actual invoice prices for drug purchases
- Statistical analysis to determine the national average
- Weekly updates published every Wednesday
The survey captures acquisition costs net of discounts, rebates, and other price concessions, providing a transparent view of what pharmacies actually pay for medications.
Why NADAC Matters for Pharmacies
NADAC is increasingly important for pharmacies for several reasons:
- Medicaid Reimbursement: Many state Medicaid programs use NADAC as the basis for pharmacy reimbursement
- Cost Transparency: Helps pharmacies understand fair acquisition costs and identify potential savings
- Contract Negotiations: Provides leverage when negotiating with wholesalers and PBMs
- Profitability Analysis: Enables pharmacies to assess margins on individual drugs
Understanding NADAC pricing helps pharmacies make informed purchasing decisions and ensure they receive fair reimbursement for the medications they dispense.
NADAC vs AWP vs WAC
There are several drug pricing benchmarks used in the pharmaceutical industry. Here's how they compare:
| Benchmark | Description |
|---|---|
| NADAC | Actual pharmacy acquisition costs from surveys |
| AWP | Average Wholesale Price – manufacturer-set list price, often inflated |
| WAC | Wholesale Acquisition Cost – manufacturer price to wholesalers before discounts |
NADAC is generally considered the most accurate reflection of actual pharmacy costs because it's based on real transaction data rather than list prices set by manufacturers.
