Unspecified firearm discharge, undetermined intent, sequela

This code signifies a long-term consequence or complication resulting from an injury caused by a firearm, where the specific type of firearm is unknown, and it cannot be determined whether the discharge was accidental, intentional self-harm, assault, or legal intervention. It indicates that the original firearm incident occurred in the past and is now causing ongoing health issues.

Use this code when documenting a current condition directly attributable to a past, unspecified firearm discharge of undetermined intent. This is appropriate for follow-up care, rehabilitation, or management of chronic issues (e.g., nerve damage, chronic pain, scarring, or psychological sequelae) stemming from such an event.

• Always sequence this code after the code for the specific sequela being treated (e.g., T90.5XXA for sequela of intracranial injury).
• Ensure documentation clearly links the current condition to a past firearm injury of undetermined intent.
• Avoid using this code for initial encounters or active treatment of the acute injury; use the appropriate acute injury code with the 7th character "A" for initial encounter.
