| 1 | | Individual Gender Identity | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | An individual's personal sense of being a man, woman, boy, girl, nonbinary, or something else. This represents an individual’s identity, ascertained by asking them what that identity is.
In the case where the gender identity is communicated by a third party, for example, if a spouse indicates the gender identity of their partner on an intake form, a Provenance resource can be used with a Provenance.target referring to the Patient, with a targetElement extension identifying the gender identity extension as the target element within the Patient resource. When exchanging this concept, refer to the guidance in the [Gender Harmony Implementation Guide](http://hl7.org/xprod/ig/uv/gender-harmony/). |
