Welcome to our Orphan Drug Exclusion list (Updated: July 2019)

The list includes HRSA’s Orphan Drug List mapped to their respective NDC identifiers. We obtained the HRSA Orphan Drug list from their official website and further mapped the Drug list to their respective NDCs, by leveraging First Databank's drug dictionary. We have strived to stay abreast of modification findings through various sources and made a note of those modifications in the report.

If you are aware of any modifications or know of any manufacturer's offering on voluntary 340B pricing, please write to us at or drop a comment below. We can update the list to serve the greater Covered Entity community that is subject to HRSA’s Orphan Drug Exclusion.
