What do states pay for prescription drugs? Explore the CMS State Drug Utilization Database
Once a quarter, the Centers for Medicare and Medicaid Services (CMS) publishes detailed Medicaid spending data down to the National Drug Code (NDC) level through what’s known as the State Drug Utilization Database. On its own, it’s somewhat challenging to use due to poor drug naming conventions and the lack of any reference pricing. However, when merged with CMS's National Average Drug Acquisition Cost (NADAC) database, it comes to life! With this viz (a.k.a visualization), you can see the average invoice prices pharmacies pay for every medication, and then compare it to what the state is being charged. Have fun exploring the madness that is Medicaid drug pricing.
