Accidental malfunction of unsp larger firearm, sequela

This code indicates a long-term health condition or complication resulting from an unintentional discharge or operational failure of an unspecified larger firearm. It signifies that the immediate injury from the malfunction has been treated, but residual effects persist.

Apply this code when documenting a patient presenting with a current health issue directly attributable to a past accidental malfunction of a larger firearm, such as a rifle or shotgun, where the specific type of firearm is not detailed. This is appropriate for conditions like chronic pain, nerve damage, or scarring that are directly linked to the original incident.

• Always assign a primary code for the specific sequela (e.g., scar, chronic pain, nerve damage) in addition to this external cause code.
• Ensure documentation clearly links the current condition to a past accidental firearm malfunction.
• Do not use for initial encounters or subsequent encounters for active treatment of the acute injury; this code is exclusively for sequelae.
