W34.110Accidental malfunction of airgun

W34.110 is the ICD-10-CM diagnosis code for accidental malfunction of airgun. It belongs to category W34 (accidental discharge and malfunction from other and unspecified firearms and guns), block W20-W49 (exposure to inanimate mechanical forces) 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 W34.11 (accidental malfunction of gas, air or spring-operated guns), W34.110 is specifically for accidental malfunction of airgun. Related codes cover paintball gun (W34.111) and other gas, air or spring-operated gun (W34.118).

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.
