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.
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.
Pipeline and calculations built by Claude (Fable 5) from the public datasets above. Educational only — verify against primary sources before acting.

How Part D pricing works →No NADAC pricing on file for this NDC — NADAC covers drugs dispensed by retail community pharmacies.
Manufacturer list price as filed — not what pharmacies actually pay after discounts.
