### Logical Definition (CLD)

This value set includes codes based on the following rules:

- Include these codes as defined in `http://snomed.info/sct` version Not Stated (use latest from terminology server)

  Code | Display
  41847000 | Adulthood
  263659003 | Adolescence
  255398004 | Childhood
  713153009 | Toddler
  3658006 | Infancy
  255407002 | Neonatal
  303112003 | Fetal period
  271872005 | Old age

- Include these codes as defined in `http://terminology.hl7.org/CodeSystem/v3-NullFlavor` version 📍4.0.0

  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.)

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
