Okay so you have something you would like to add to the CDM and there is an existing OMOP vocabulary we can bring in to support it. In this case, please open an issue on the vocabulary github with the details of what you need added as data elements in the CDM must have a vocabulary in place before they can be implemented. The team will follow up with you should they need additional information.

Once that request is made, 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.
