Explosion on board other powered watercraft, subs encntr

This code indicates that a patient is receiving follow-up care for injuries sustained from an explosion that occurred on a powered watercraft other than a ship, such as a motorboat, yacht, or personal watercraft. The initial injury has already been treated, and the patient is now in the healing phase, requiring ongoing medical attention.

This code is appropriate for subsequent visits related to the initial explosion injury, such as wound care, physical therapy, medication management, or follow-up appointments for complications. It should be used after the acute phase of treatment has concluded and the patient is no longer in active treatment for the immediate injury.

• Always assign an external cause code for the specific injury(ies) sustained from the explosion.
• Ensure the "D" seventh character is appropriate for subsequent encounters; "A" is for initial, "S" for sequela.
• Verify the type of powered watercraft involved to ensure it falls under "other powered watercraft" and not a "ship."
