About Y35.00

Y35.00 is the ICD-10-CM diagnosis code for legal intervention involving unspecified firearm discharge. 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 Y35.0, choose Y35.00 (unspecified firearm discharge) only when documentation doesn't support a more specific option: injury by machine gun (Y35.01), injury by handgun (Y35.02), injury by rifle pellet (Y35.03), injury by rubber bullet (Y35.04) and other firearm discharge (Y35.09).

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.
