Explosion on board merchant ship, sequela

This code indicates a health condition or injury that is a residual effect of an explosion that occurred on a merchant ship. It signifies a long-term or late-developing complication directly attributable to the initial incident. This could include chronic pain, psychological disorders, or permanent physical impairments resulting from the explosion.

Use this code when documenting a patient's current medical condition that is a direct consequence of an explosion previously sustained on a merchant ship. This applies to follow-up encounters for conditions like PTSD, chronic burns, hearing loss, or orthopedic injuries that have stabilized but require ongoing management due to the original event. It should be used after the acute phase of the injury has passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., T95.0 for sequelae of burn).
• Ensure documentation clearly links the current condition to the past explosion on a merchant ship.
• Verify the "S" seventh character for sequela, indicating a late effect of the external cause.
