Accidental discharge of machine gun, subsequent encounter

This code signifies an injury resulting from the unintended firing of a machine gun, specifically when the patient is receiving follow-up care after the initial treatment of the injury. This could involve complications, ongoing treatment, or rehabilitation related to the original incident.

Apply this code when a patient presents for subsequent care following an accidental machine gun discharge. This includes visits for wound checks, infection management, physical therapy, or mental health support directly related to the initial injury. It is used after the acute phase of treatment has concluded.

• Always pair this external cause code with an injury code (e.g., T-code for gunshot wound) to fully describe the patient's condition.
• Ensure the "D" seventh character is appropriate for subsequent encounters; "A" is for initial encounters and "S" for sequela.
• Verify documentation clearly indicates the injury was due to an accidental discharge of a machine gun, not another firearm type or intentional act.
