Y36.20War operations involving unspecified explosion and fragments

Y36.20 is the ICD-10-CM diagnosis code for war operations involving unspecified explosion and fragments. 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 Y36.2, choose Y36.20 (unspecified explosion and fragments) only when documentation doesn't support a more specific option: explosion of aerial bomb (Y36.21), explosion of guided missile (Y36.22), explosion of improvised explosive device [IED] (Y36.23), explosion due to accidental detonation and discharge of own munitions or munitions launch device (Y36.24), fragments from munitions (Y36.25), fragments of improvised explosive device [IED] (Y36.26), fragments from weapons (Y36.27) and other explosions and fragments (Y36.29).

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.
