War op w explosn of sea-based artlry shell, milt, sequela

This code signifies a long-term health consequence or complication arising from a military service member's exposure to an exploding artillery shell in a sea-based war operation. It indicates that the initial injury or event has led to a lasting condition requiring ongoing medical attention.

Apply this code when documenting a sequela (e.g., chronic pain, PTSD, amputation-related issues, hearing loss) directly attributable to a past war-related incident involving a sea-based artillery shell explosion affecting military personnel. This code is appropriate for follow-up encounters long after the initial injury has healed, but its effects persist.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., T90.5 for sequela of intracranial injury).
• Ensure documentation clearly links the current condition to the specified historical event.
• The "S" at the end indicates sequela; do not use for initial or subsequent encounters for the acute injury.
