About Y35.1
Y35.1 is the ICD-10-CM diagnosis code for legal intervention involving explosives. It belongs to category Y35 (legal intervention), 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 4 subcodes must be used instead.
Within Y35 (legal intervention), Y35.1 is specifically for legal intervention involving explosives. Related codes cover involving firearm discharge (Y35.0), involving gas (Y35.2), involving blunt objects (Y35.3), involving sharp objects (Y35.4), involving other specified means (Y35.8) and means unspecified (Y35.9).
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.
