Accidental discharge from other specified firearms, sequela

This code describes the long-term effects or complications arising from an unintentional firing of a firearm that is not a handgun, rifle, or shotgun. This could include injuries from antique firearms, homemade guns, or other less common types of firearms. The "sequela" indicates that the initial injury has healed, but residual conditions or chronic problems persist.

Apply this code when documenting a patient presenting with a current condition (e.g., chronic pain, nerve damage, scar tissue, functional impairment) directly attributable to an accidental discharge from a specified firearm other than the common types, and the initial injury occurred in the past. This code is used for the late effects of the injury, not the acute event itself.

• Always sequence this code second, after the code identifying the specific sequela (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to a past accidental discharge from a non-specified firearm.
• Verify the firearm type is explicitly stated as "other specified" and not a handgun, rifle, or shotgun to avoid miscoding.
