Program Area: Distributed Data Collection (DDC) for RA Including HCRP/EDGE Server

Question: In addition to the National Drug Code (NDC) Serial Presence Detect (SPD) file, is CMS using a secondary source for NDCs in the EDGE reference table?

Answer: At this time, CMS is not using a secondary source for NDCs in the EDGE reference table. CMS is aware of the concern issuers have raised regarding NDCs' start and end dates. If there is a modification to the NDCs in the future, it would be to better address concerns raised regarding the start and end dates, as opposed to the NDCs themselves. We are reviewing these concerns and considering possible solutions. The NDC SPD Data Elements will remain the sole source file for the 11 digit NDC codes.
