About Y38.8

Y38.8 is the ICD-10-CM diagnosis code for terrorism involving other and unspecified means. It belongs to category Y38 (terrorism), 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 3 subcodes must be used instead.

Within Y38, choose Y38.8 (involving other and unspecified means) only when documentation doesn't support a more specific option: involving explosion of marine weapons (Y38.0), involving destruction of aircraft (Y38.1), involving other explosions and fragments (Y38.2), involving fires, conflagration and hot substances (Y38.3), involving firearms (Y38.4), involving nuclear weapons (Y38.5), involving biological weapons (Y38.6), involving chemical weapons (Y38.7) and 1 more.

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

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