Y23.1Hunting rifle discharge, undetermined intent

Y23.1 is the ICD-10-CM diagnosis code for hunting rifle discharge, undetermined intent. It belongs to category Y23 (rifle, shotgun and larger firearm discharge, undetermined intent), 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.

Within Y23 (rifle, shotgun and larger firearm discharge, undetermined intent), Y23.1 is specifically for hunting rifle discharge, undetermined intent. Related codes cover shotgun discharge, undetermined intent (Y23.0), military firearm discharge, undetermined intent (Y23.2), machine gun discharge, undetermined intent (Y23.3), other larger firearm discharge, undetermined intent (Y23.8) and unspecified larger firearm discharge, undetermined intent (Y23.9).

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.
