About Y35

Y35 is the ICD-10-CM diagnosis code for legal intervention. 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Y35.0 (involving firearm discharge), Y35.1 (involving explosives), Y35.2 (involving gas), Y35.3 (involving blunt objects), Y35.4 (involving sharp objects), Y35.8 (involving other specified means) and Y35.9 (means unspecified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
