About X93

X93 is the ICD-10-CM diagnosis code for assault by handgun discharge. It belongs to block X92-Y09 (assault) 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: X93.XXXA (initial encounter), X93.XXXD (subsequent encounter) and X93.XXXS (sequela).

Don't report X93 together with the conditions in its Excludes1 note: Very pistol (X95.8).

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