1.2.0 - CI Build

Canadian Baseline, published by HL7 Canada - FHIR Implementation Work Group. This guide is not an authorized publication; it is the continuous build for version 1.2.0 built by the FHIR (HL7® FHIR® Standard) CI Build.

## ValueSet: Birth Sex

Official URL: http://hl7.org/fhir/ca/baseline/ValueSet/birthsex | Version: 1.2.0
Draft as of 2019-03-08 | Computable Name: BirthSex

Codes for documenting sex at birth. (Replicates the birthsex ValueSet in US-Core-R4 for interoperability.)

References

- Extension: Birth Sex

### Logical Definition (CLD)

This value set includes codes based on the following rules:

- Include these codes as defined in `http://terminology.hl7.org/CodeSystem/v3-AdministrativeGender` version 📦3.0.0

  Code | Display | Definition
  F | Female | Female
  M | Male | Male

- Include these codes as defined in `http://terminology.hl7.org/CodeSystem/v3-NullFlavor` version 📦3.0.0

  Code | Display | Definition
  UNK | Unknown | **Description:**A 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: 1. Those properties themselves directly translate to a semantic of "unknown". (E.g. a local code sent as a translation that conveys 'unknown') 2. 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.)

### Expansion

Expansion performed internally based on:

- codesystem AdministrativeGender v3.0.0 (CodeSystem)
- codesystem NullFlavor v3.0.0 (CodeSystem)

This value set contains 3 concepts

System | Code | Display (en) | JSON | XML

Explanation of the columns that may appear on this page:

Level | A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System | The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code | The code (used as the code in the resource instance)
Display | The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition | An explanation of the meaning of the concept
Comments | Additional notes about how to use the code
