Y36.09War operations involving explosion of other marine weapons

Y36.09 is the ICD-10-CM diagnosis code for war operations involving explosion of other marine weapons. 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 Y36.0, choose Y36.09 (explosion of other marine weapons) only when documentation doesn't support a more specific option: explosion of unspecified marine weapon (Y36.00), explosion of depth-charge (Y36.01), explosion of marine mine (Y36.02), explosion of sea-based artillery shell (Y36.03), explosion of torpedo (Y36.04) and accidental detonation of onboard marine weapons (Y36.05).

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.
