Accidental malfunction of other larger firearm, sequela

This code signifies the long-term effects or complications arising from an accidental malfunction of a large firearm, excluding rifles, shotguns, and pistols. These sequelae can include chronic pain, nerve damage, scarring, or functional limitations that persist after the initial injury has healed. The original injury event itself is no longer the primary focus, but rather the lasting consequences.

Use this code when documenting a patient presenting with a current condition that is a direct result of an accidental malfunction of a large firearm (e.g., machine gun, artillery piece, or other non-specified large firearm) that occurred in the past. This code is appropriate for follow-up visits where the sequela is being treated or evaluated, and the acute injury has resolved.

• Always sequence this code after the code describing the specific sequela (e.g., chronic pain, scar, nerve damage).
• Ensure documentation clearly links the current condition to the past accidental firearm malfunction.
• Verify the firearm involved was a "larger firearm" other than a rifle, shotgun, or pistol to ensure accurate code selection.
