We have 9 and 11 digit NDC codes for our administered drugs. What is the method to convert from a 9 or 11 digit NDC code to the OMOP concept_code so I can find the appropriate concept_id?
Thanks,

Use the CONCEPT_REPLATIONSHIP table, looking for the âMapsToâ relationship_id, where concept_1 is the NDC concept (found by looking for for the concept_code = the NDC code) and concept_2 will be the standard concept (from RxNorm) that this NDC maps to. Use the concept_2 as the value you write to in DRUG_EXPOSUREâs drug_concept_id column.

Itâs described somewhere, but I canât find it.
Here is the gist:
Hi: Trying to find NDC for continuous glucose monitoring devices:
But it seems that OMOPâs Athena doesnt have these codes
Does that mean that these NDC are not mapped in OMOP? If not, how do we get glucose devices mapped?
Athena does not find this specific NDC code, does this indicate a general class of devices is missing?
It means that the official NDC source (which is FDA) doesnât provide us with those codes. Might indicate that they donât have them or that your codes are wrong.
For example, other âverioâ are there:

If you believe that your codes are correct, then submit the names, codes and start/end dates here:
Thank you, the NDC codes are correct and our organizationâs NDC codes are derived from Medi-Span. Is there a general strategy to integrate Medi-Span codes? Or should I pursue a one-off as per your link?
Medi-Span is one of the sources for NDCs. Apparently, the NLM decided against this one. Feel free, as @aostropolets said, to submit the code and we will bring it up with them.
However: non-drug NDCs are step children anyway. NDC, which stands for National Drug Code, was designed as a system of unique product identifiers used in the United States for drugs intended for human use. Over time, manufacturers started making NDCs for everything that is sold in a pharmacy, drug or not, including glucose sticks. There really is no authority that oversees these funny NDCs. So, I wouldnât bet the farm on those kinds of codes.
Thank you for this response and general background info primer. My current interest is to identify continuous glucose monitoring (CGM) device users. I will review the task of curating a comprehensive set of NDCs to identify CGM devices and related supplies. Strips were just a test case. Great community here, thanks all !!!
