NDC Code Reuse? #1

Open sgpeter1 opened 5 years ago

sgpeter1 commented 5 years ago

Just a question—did you run across any significant NDC code "reuse" when constructing this? That is, did you notice a substantial number of NDC codes being used for totally different drugs over the course of time?

I am also interested in this question. Is there any reason that the dashes were taken out of the NDC product code in the output files?

Also interested in learning about this.
