Accidental discharge of machine gun, sequela

This code describes the long-term effects or complications arising from an accidental injury caused by the discharge of a machine gun. It indicates that the initial injury has healed, but the patient continues to experience residual conditions directly attributable to that event. These sequelae can include chronic pain, nerve damage, scarring, or functional limitations.

Use this code when documenting a patient's current condition that is a direct consequence of an accidental machine gun discharge that occurred in the past. This applies to follow-up visits for chronic issues, rehabilitation, or management of permanent disabilities stemming from the original injury. Do not use for the initial acute injury.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Ensure documentation clearly links the current condition to the past accidental machine gun discharge.
• An external cause code for the initial event (e.g., W33.03XA for initial encounter) would have been used at the time of the acute injury.
