Handgun discharge, undetermined intent, sequela

This code signifies a long-term complication or condition arising from an injury caused by a handgun discharge where the intent (accidental, self-harm, assault) could not be determined. It is used to report the residual effects of such an event, not the initial injury itself.

Apply this code when a patient presents for treatment of a chronic issue directly attributable to a past handgun injury of undetermined intent. Examples include ongoing pain, nerve damage, or functional limitations that are a direct consequence of the original incident. This code is appropriate for follow-up care after the acute phase of the injury has passed.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., chronic pain, scar formation).
• Ensure documentation clearly links the current condition to a past handgun injury and explicitly states the undetermined intent.
• Do not use for initial encounters or acute care of the original injury; use the acute injury code (Y22.XXXA) for those scenarios.
