About Y22

Y22 is the ICD-10-CM diagnosis code for handgun discharge, undetermined intent. It belongs to block Y21-Y33 (event of undetermined intent) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Y22.XXXA (initial encounter), Y22.XXXD (subsequent encounter) and Y22.XXXS (sequela).

The conditions in its Excludes2 note aren't part of Y22, but may be coded alongside it if the patient has both: very pistol (Y24.8).

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