War op w explosn of unsp marine weapon, milt, sequela

This code signifies a long-term health condition or complication resulting from a military service member's exposure to an explosion from an unspecified marine weapon during wartime. It indicates that the initial injury or event occurred in a war zone due to an underwater or sea-based explosive device, and the patient is now presenting with a residual effect of that incident.

Apply this code when documenting a sequela, such as chronic pain, neurological deficits, hearing loss, or psychological disorders, that is directly attributable to an explosion of an unspecified marine weapon sustained by military personnel during war operations. This code is appropriate for follow-up encounters where the acute injury has resolved, but the patient continues to experience lasting effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., T90.5XXS for sequela of intracranial injury).
• Ensure documentation clearly links the current condition to the past war-related marine weapon explosion.
• Verify that the patient was military personnel and the event occurred during war operations.
