Milt op involving explosion of depth-chg, civilian, sequela

This code signifies a long-term health consequence or complication arising from a civilian's exposure to a depth-charge explosion during military operations. It indicates that the initial injury has healed, but residual effects, such as chronic pain, hearing loss, or psychological trauma, are still present and being treated.

Apply this code when documenting a patient's current medical condition that is a direct result of a past depth-charge explosion during military operations, and the patient was a civilian at the time of the incident. This code is appropriate for follow-up encounters addressing the ongoing sequelae, not the initial acute injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., Tinnitus, PTSD).
• Ensure documentation clearly links the current condition to the past depth-charge explosion and specifies the patient's civilian status.
• This "S" code indicates a sequela; do not use it for initial or active treatment of the acute injury.
