Laterality

 

The official URL for this extension is:

http://mcodeinitiative.org/us/mcode/StructureDefinition/obf-datatype-Laterality-extension

Body side of the body location, if needed to distinguish from a similar location on the other side of the body.

The laterality element is part of BodyLocation, a flexible structure that allows the location to be determined by a single code, or a code plus laterality and/or orientation. The body location can also be specified in relation to one or more body landmarks. SNOMED CT is used in all cases.

  • Code only: The code should include (precoordinate) laterality and/orientation to the degree necessary to completely specify the body location.
  • Code plus laterality and/or orientation: The basic code augmented by codes specifying the body side and/or anatomical orientation.
  • Relation to landmark: The location relative to a landmark is specified by:
    1. Establishing the location and type of landmark using a body site code and optional laterality/orientation, and
    2. Specifying the direction and distance from the landmark to the body location.

Note that BodyLocation is a data type (a reusable structure), not a stand-alone entity. The concept is similar to how a postal address can apply to a person, location, or organization. This contrasts with FHIR’s stand-alone BodySite (aka BodyStructure in r4) which ‘is not … intended for describing the type of anatomical location but rather a specific body site on a specific patient’ (FHIR 3.5).
