About Y36.50
Y36.50 is the ICD-10-CM diagnosis code for war operations involving unspecified effect of nuclear weapon. 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 Y36.5, choose Y36.50 (operations involving unspecified effect of nuclear weapon) only when documentation doesn't support a more specific option: operations involving direct blast effect of nuclear weapon (Y36.51), operations involving indirect blast effect of nuclear weapon (Y36.52), operations involving thermal radiation effect of nuclear weapon (Y36.53), operation involving nuclear radiation effects of nuclear weapon (Y36.54) and operation involving other effects of nuclear weapons (Y36.59).
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.
