### 10.5.3 targetSiteCode

Each observation needs to fully specify its site/location.

COND: If the observation site is not pre-coordinated in the observation/code, it SHALL be specified in the observation/targetSiteCode.

COND: The qualifier element for laterality SHALL be present if the targetSiteCode represents a paired body part and laterality is not pre-coordinated in the targetSiteCode.

COND: The qualifier element for topographical modifier SHALL be present if the targetSiteCode does not fully specify the observation location in sufficient detail.

### Note

Inclusion of a site name in a labeled subsection title (see Section 9.8.9) does not imply a finding site for observations within that subsection. The title is not semantically part of the post-coordination, and target sites must be explicitly identified.

See Example 10.5-2 “Quantity measurement observation example 2”, an example of a measurement using a topographical modifier qualifier.
