Explosion on board other powered watercraft, sequela

This code describes a health condition or injury that is a residual effect or complication stemming from an explosion that occurred on a powered watercraft other than a ship, boat, or warship. This could include long-term physical injuries, psychological trauma, or other chronic issues directly attributable to the initial explosive event.

Use this code when documenting a patient presenting with a current sequela (e.g., chronic pain, PTSD, permanent disfigurement, hearing loss) that is a direct result of an explosion on a non-specified powered watercraft. This code is appropriate for encounters where the initial injury has healed, but its lasting effects are being treated or evaluated.

• Always assign an additional code(s) for the specific nature of the sequela (e.g., T90.5XXA for sequela of head injury).
• Ensure documentation clearly links the current condition to the past explosion event.
• This "S" extension indicates sequela and should be used for conditions that are residuals of a past injury or disease.
