When a measurement is out of normal range, it may be flagged using the interpretationCode. Very abnormal values, often denoted as exceeding "panic limits", or as "actionable" or "critical findings", may have values such as (LL, ObservationInterpretation, "low alert"), (HH, ObservationInterpretation, "high alert"), or (AA, ObservationInterpretation, "abnormal alert").

The translation element of the interpretationCode may be used to provide a further classification as defined in a regionally- or professionally-specified value set. This template identifies an optional value set for the ACR Actionable Finding categories 1, 2, and 3, as defined by: Larson PA, et al. J Am Coll Radiol 2014; published online. DOI 10.1016/j.jacr.2013.12.016.

The narrative text associated with the actionable finding SHOULD be highlighted using styleCode Bold. See Section 9.1.1.1.

Actionable findings that require a specific follow-up action or procedure SHOULD be referenced from a recommendation in the 9.8.11 Recommendation Section.

Communication of actionable findings SHOULD be documented in the 9.8.10 Communication of Actionable Findings Section.
