Accidental malfunction from oth firearms, sequela

This code describes a long-term health condition or complication resulting from an accidental discharge or malfunction of a firearm other than a handgun, rifle, or shotgun. It indicates that the patient is presenting for care related to the lasting effects of such an incident, rather than the initial injury itself.

Use this code when documenting a patient encounter for a sequela (e.g., chronic pain, nerve damage, scarring, psychological trauma) directly attributable to an accidental malfunction of an unspecified firearm. This applies to follow-up visits or when the residual effects are the primary reason for the current encounter, long after the initial injury has healed.

• Always assign a sequela code (e.g., T90-T98) first to specify the nature of the residual condition.
• Ensure documentation clearly links the current condition to a past accidental firearm malfunction.
• Verify the firearm type was not a handgun, rifle, or shotgun; otherwise, a more specific W34.0- series code would be appropriate.
