Assault by machine gun, sequela

This code signifies a long-term health condition or complication resulting from a past assault involving a machine gun. It indicates that the patient is presenting for treatment of a residual effect directly attributable to this specific type of violent injury, rather than the acute injury itself.

Apply this code when a patient is being treated for a sequela (e.g., chronic pain, neurological deficits, psychological trauma, scarring, or loss of function) that originated from an assault by a machine gun. This code is used after the initial acute injury has healed and the patient is experiencing ongoing consequences.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past machine gun assault.
• The "S" in the 7th character indicates sequela and must always be used for this type of encounter.
