About Y37.26

Y37.26 is the ICD-10-CM diagnosis code for military operations involving fragments of improvised explosive device [IED]. It belongs to category Y37 (military operations), 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 Y37.2 (military operations involving other explosions and fragments), Y37.26 is specifically for military operations involving fragments of improvised explosive device [IED]. Related codes cover unspecified explosion and fragments (Y37.20), explosion of aerial bomb (Y37.21), explosion of guided missile (Y37.22), explosion of improvised explosive device [IED] (Y37.23), explosion due to accidental detonation and discharge of own munitions or munitions launch device (Y37.24), fragments from munitions (Y37.25), fragments from weapons (Y37.27) and other explosions and fragments (Y37.29).

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.
