Milt op involving explosion of depth-charge, civilian, subs

This code signifies an injury or health condition sustained by a civilian due to the detonation of a depth charge during military operations. It specifically applies to follow-up care for such an injury, indicating that the initial treatment has already been rendered.

Use this code for any subsequent encounters, such as follow-up appointments, rehabilitation, or management of long-term complications, for a civilian patient whose injury originated from a depth-charge explosion in a military operation. This would include scenarios like wound checks, physical therapy sessions, or mental health evaluations related to the initial trauma.

• Ensure the patient is explicitly documented as a civilian and the incident involved a depth-charge explosion during military operations.
• Verify that this is not the initial encounter for the injury; if it is, a different encounter character (A) would be used.
• Always code the specific injury or condition resulting from the explosion first, followed by this external cause code.
