About Y36.31

Y36.31 is the ICD-10-CM diagnosis code for war operations involving gasoline bomb. It belongs to category Y36 (operations of war), 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 2 subcodes must be used instead.

Within Y36.3 (war operations involving fires, conflagrations and hot substances), Y36.31 is specifically for war operations involving gasoline bomb. Related codes cover unspecified fire, conflagration and hot substance (Y36.30), incendiary bullet (Y36.32), flamethrower (Y36.33) and other fires, conflagrations and hot substances (Y36.39).

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.

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