Assault by machine gun, subsequent encounter

This code signifies an injury resulting from an assault where a machine gun was the weapon used, and the patient is receiving follow-up care for this injury. It indicates that the initial treatment has already occurred, and the current encounter is for ongoing management, healing, or complications related to the original incident.

Use this code for encounters where a patient is being seen for complications, aftercare, or sequelae directly related to a machine gun assault that occurred previously. This includes visits for wound checks, physical therapy, mental health support, or management of chronic pain stemming from the initial injury.

• Ensure the "D" seventh character is appropriate for a subsequent encounter, indicating active treatment or follow-up care.
• Always code the specific injury(ies) sustained from the assault first, followed by this external cause code.
• Do not use for the initial treatment of the injury; refer to codes with the "A" seventh character for initial encounters.
