About Y38

Y38 is the ICD-10-CM diagnosis code for terrorism. It belongs to block Y35-Y38 (legal intervention, operations of war, military operations, and terrorism) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Y38.0 (involving explosion of marine weapons), Y38.1 (involving destruction of aircraft), Y38.2 (involving other explosions and fragments), Y38.3 (involving fires, conflagration and hot substances), Y38.4 (involving firearms), Y38.5 (involving nuclear weapons), Y38.6 (involving biological weapons), Y38.7 (involving chemical weapons) and 2 more.

Use an additional code for place of occurrence (Y92.-).
