The goal here is to add MedDRA identifiers (https://www.wikidata.org/wiki/Property:P3201) to Wikidata using the World Health Organization mappings from ICD-10 to MedDRA.
The mappings are described in https://cdn.who.int/media/docs/default-source/classification/icd/icd-10/icd-10-to-meddra-mapping-conventions.pdf and are available at https://cdn.who.int/media/docs/default-source/classification/icd/icd-10/icd-10-to-meddra-map---june-2023---codes-mapping.xlsx
Heuristic: inferred by common ICD-10 mappings on Wikidata and on source (Q121619566)
