How can I download the non-standard to standard map file?
I cannot locate the ICD10 code I21.01 in the CONCEPTS.csv file of mappings to extract its concept ID in the ICD10 vocabulary downloaded from Athena
This code is present in Athena: Athena
The Non-standard to Standard map (OMOP) shows that this ICD10 code I21.01 is mapped to SNOMED concept ID 46270162.
I downloaded the ICD10 and ICD10PCS vocabularies from
(I need to convert several hundred such ICD10 codes to SNOMED concept IDs.)
Thanks so much!
