340B Validation Service.

The only party financially harmed due to 340B duplicate discounts are drug manufacturers.  HRSA and CMS continue to struggle to offer real solutions to protect manufacturers from paying duplicate discounts.

340B duplicate discounts are a problem.

Drug manufacturers who participate in the Medicaid Drug Rebate Program are likely paying 1%-4% too much due to 340B duplicate discounts.  This can be tens of millions of dollars for a large manufacturer every year.


The government cannot solve the problem.

The only party financially harmed due to 340B duplicate discounts are drug manufacturers.  HRSA and CMS continue to struggle to offer real solutions to protect manufacturers from paying duplicate discounts.   


We offer the complete solution, guaranteed.

Give us your claims level data - it doesn’t even have to be standardized - and we do the rest.  We identify suspected duplicate discounts and work with the covered entities to confirm if a 340B drug was dispensed, and give you a report that is guaranteed to be accepted as a valid dispute by the state.
