War operations, unspecified, initial encounter

This code signifies an injury or condition resulting from military conflict or hostile actions where the specific type of war operation is not documented. It indicates that the patient is receiving initial active treatment for this war-related event.

Apply this code when a patient presents with an injury or illness directly attributable to war operations, but the medical record lacks specific details about the nature of the conflict (e.g., land warfare, naval warfare). This is appropriate for the initial phase of care following such an event.

• Only use this code when the specific type of war operation cannot be determined from the documentation.
• Ensure the "A" seventh character is used for the initial encounter for active treatment.
• Always sequence this code as a secondary diagnosis, following the code for the specific injury or condition.
