This page is part of the Medicolegal Death Investigation (MDI) (v1.0.0: STU 1) based on FHIR R4. This is the current published version. For a full list of available versions, see the Directory of published versions

ValueSet: ValueSet - Units of Age

Official URL: http://hl7.org/fhir/us/mdi/ValueSet/ValueSet-units-of-age Version: 1.0.0
Active as of 2022-02-27 Computable Name: ValueSetUnitsOfAge

A set of codes for specifying the units used when recording age (days, years, etc.). The MDI ValueSet - Units of Age artifact overlaps with the VRDR Units of Age artifact.

Logical Definition (CLD)

This value set includes codes based on the following rules:

  • Include these codes as defined in http://unitsofmeasure.org
    CodeDisplay
    minMinutes
    dDays
    hHours
    moMonths
    aYears
  • Include these codes as defined in http://terminology.hl7.org/CodeSystem/v3-NullFlavor

    UNKunknown**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
