Y36.49War operations involving other forms of conventional warfare

Y36.49 is the ICD-10-CM diagnosis code for war operations involving other forms of conventional warfare. 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 Y36.4, choose Y36.49 (other forms of conventional warfare) only when documentation doesn't support a more specific option: rubber bullets (Y36.41), firearms pellets (Y36.42), other firearms discharge (Y36.43), unarmed hand to hand combat (Y36.44), combat using blunt or piercing object (Y36.45), intentional restriction of air and airway (Y36.46) and unintentional restriction of air and airway (Y36.47).

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.
