Wildcards in ICD-10 codes

Dear ORDO developers,

I am looking at the conversion between ICD-10 and EFO on the EBI OLS website. Some ICDs have been labelled with wildcards such as `+` and `*` (see example below). How these should be interpreted?

xref: ICD10:A39.0+ {source="ORDO:33475/e", source="Orphanet:33475"}
xref: ICD10:G01* {source="ORDO:33475/e", source="Orphanet:33475"}

Regards,

Luca
