Milt op w explosn of sea-based artlry shell, civ, sequela

This code signifies a long-term consequence or complication arising from a civilian's exposure to an explosion of a sea-based artillery shell during military operations. It indicates that the initial injury has resolved, but residual effects persist and require ongoing medical attention.

Apply this code when documenting conditions such as chronic pain, hearing loss, traumatic brain injury sequelae, or psychological disorders (e.g., PTSD) that are directly attributable to a past incident involving a sea-based artillery shell explosion affecting a civilian. This code is appropriate for follow-up encounters after the acute injury has been treated.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the historical explosion event.
• Verify the patient's civilian status and the military operations context are explicitly stated in the medical record.
