@Chris_Knoll , I just tested the latest scripts you mentioned on our data. I do now see PC and DPC for custom codes (e.g. local codes greater than 2 Billion) that are considered standard codes. However, PC and DPC are not generated for non-standard codes > 2 Billion, or for non-standard source codes (such as ICD-10 codes).
So, I’d be happy to augment Achilles to create person counts for _source_concept_id, but I need some guidance on how to incorporate those new scripts into the Achilles workflow.
