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.
