This value set includes SNOMED CT codes and the HL7 V3 code for the concept “unknown”.

References

This value set uses SMOMED CT codes, which are available in VSAC. LOINC also provides an example list LL4053-6 for the code 86645-9 (Pregnancy intention in the next year - Reported) used in the US Core Observation Pregnancy Intent Profile. The table below provides implementers with a concept mapping between these codes.

SNOMED CT SNOMED CT Preferred Name LOINC Answer ID Answer

Logical Definition (CLD)

This value set includes codes based on the following rules:

  • Import all the codes that are contained in Pregnancy Intention
  • Include these codes as defined in http://terminology.hl7.org/CodeSystem/v3-NullFlavor
    CodeDisplayDefinition
    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
