URI for domain value for Sex in ISO 22220


Is anyone aware or have assigned a URI (for use in FHIR) for the Alternative Code Data Domain for Sex (i.e. M, F, I, U) in ISO 22220 - Identification of Subjects of Care (2011) ? I’m specifically interested in using the code “I” and would like to a attribute it properly.


this was discused on the FHIR email list, and the suggested system was urn:iso:std:iso:22220:sex

Thanks Graham for discussing this.
