About Y36
Y36 is the ICD-10-CM diagnosis code for operations of war. It belongs to 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 11 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: Y36.0 (weapons), Y36.1 (aircraft), Y36.2 (fragments), Y36.3 (substances), Y36.4 (warfare), Y36.5 (weapons), Y36.6 (weapons), Y36.7 (warfare) and 3 more.
Don't report Y36 together with the conditions in its Excludes1 note: injury to military personnel occurring during peacetime military operations (Y37.-) and military vehicles involved in transport accidents with non-military vehicle during peacetime (V09.01, V09.21, V19.81, V29.818, V39.81, V49.81, V59.81, V69.81, V79.81).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
