Other firearm discharge, undetermined intent, sequela

This diagnosis code signifies a long-term consequence or late effect resulting from a firearm discharge where the intent (e.g., accidental, self-harm, assault) could not be determined. It is used when the initial injury has healed, but the patient continues to experience residual problems directly attributable to the original firearm incident.

Apply this code when documenting follow-up care for conditions such as chronic pain, nerve damage, scarring, or psychological sequelae stemming from an indeterminate firearm injury. This is appropriate for encounters occurring after the acute phase of the injury has passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to a past firearm injury of undetermined intent.
• Verify that the encounter is for a late effect and not for the initial treatment of the injury.
