One drug, every price
The same NDC has different prices depending on who is paying. Units differ between rungs — compare within a rung over time, not rung against rung, unless the units match.
ⓘ How this was built
Data sources
- CMS NADAC (pharmacy acquisition, weekly)
- CMS Part B ASP quarterly payment limits
- CMS Maximum Fair Prices (IRA negotiated, NDC-level)
- Medicare Part D Spending by Drug (data.cms.gov, name-matched)
- VA FSS / Big4 federal contract prices (va.gov, twice monthly)
- ACA Federal Upper Limits + weighted AMP (data.medicaid.gov, monthly)
- California SB-17 WAC filings (list price, per package)
Method
Each rung is the newest figure for this NDC from one federal price system, shown with its own unit. Part D is matched by drug name because CMS publishes no NDCs there; it is gross spending, before confidential rebates.
