This Code system is used in the following value sets:

The gender of a person used for administrative purposes.

This code system defines the following codes:

male MaleMaleMale
female FemaleFemaleFemale
other OtherOtherThe gender of a person could not be uniquely defined as male or female, such as hermaphrodite.
unknown UnknownUnknownA proper value is applicable, but not known. Usage Notes: This means the actual value is not known. If the only thing that is unknown is how to properly express the value in the necessary constraints (value set, datatype, etc.), then the OTH or UNC flavor should be used. No properties should be included for a datatype with this property unless: Those properties themselves directly translate to a semantic of "unknown". (E.g. a local code sent as a translation that conveys 'unknown') Those properties further qualify the nature of what is unknown. (E.g. specifying a use code of "H" and a URL prefix of "tel:" to convey that it is the home phone number that is unknown.)
