Okay so you have something you would like to add to the CDM but there is not an existing OMOP vocabulary nor an open-source vocabulary we can bring in to support it. In this case, please contact the vocabulary team on next steps as data elements in the CDM must have a vocabulary in place before they can be implemented.

Vocabulary Teams Channel

Once you come to consensus with the vocabulary team regarding your needs, please follow the CDM Request Process to begin the steps soliciting a change or addition to the model itself. Need more guidance? Consider contacting the CDM Working Group on our GitHub or Teams Channel.
