About Y38.80

Y38.80 is the ICD-10-CM diagnosis code for terrorism involving 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 Y38.8, choose Y38.80 (unspecified means) only when documentation doesn't support a more specific option: suicide bomber (Y38.81) and other means (Y38.89).

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.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
