Y24.9Unspecified firearm discharge, undetermined intent

Y24.9 is the ICD-10-CM diagnosis code for unspecified firearm discharge, undetermined intent. It belongs to category Y24 (other and unspecified 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 Y24, choose Y24.9 (Unspecified firearm discharge, undetermined intent) only when documentation doesn't support a more specific option: airgun discharge, undetermined intent (Y24.0) and other firearm discharge, undetermined intent (Y24.8).

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.
