About Y37.02

Y37.02 is the ICD-10-CM diagnosis code for military operations involving explosion of marine mine. 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 Y37.0 (military operations involving explosion of marine weapons), Y37.02 is specifically for military operations involving explosion of marine mine. Related codes cover explosion of unspecified marine weapon (Y37.00), explosion of depth-charge (Y37.01), explosion of sea-based artillery shell (Y37.03), explosion of torpedo (Y37.04), accidental detonation of onboard marine weapons (Y37.05) and explosion of other marine weapons (Y37.09).

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.
