| - | There is no one comprehensive repository of all NDC codes available. Instead, the FDA, the NLM and a number of commercial providers distribute NDC code lists. OHDSI is trying to create a list as complete as possible by combining many sources and adding NDC codes found in from observational databases. If NDC codes are missing from the CONCEPT table, please report those cases to the [http://forums.ohdsi.org/c/cdm-builders|OHDSI Forum]. | + | |
