Civilian in water injured by military watercraft, subs

This code signifies an injury sustained by a civilian in the water due to contact with a military watercraft. The "D" in the seventh character indicates that this is a subsequent encounter for care after the initial treatment of the injury. This could involve follow-up appointments, cast changes, or ongoing rehabilitation.

Apply this code when a civilian patient presents for follow-up care related to an injury initially caused by a military vessel while the patient was in the water. This includes situations like a civilian swimmer or boater being struck by a military ship or submarine, or injured by its wake.

• Ensure the patient is explicitly documented as a civilian and the watercraft as military.
• Verify that the encounter is for ongoing care, not the initial treatment of the injury.
• Always code the specific nature of the injury (e.g., fracture, laceration) first, followed by this external cause code.
