The location relative to a landmark is specified by: * Specifying the location and type of landmark using a body site code and optional laterality/orientation, * Specifying the direction from the landmark to the body location, and * Specifying the distance from the landmark to the body location. The RelationToLandmark 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.
