Explosion on board fishing boat, subsequent encounter

This code describes injuries or health conditions resulting from an explosion that occurred on a fishing boat, specifically for encounters after the initial treatment. It indicates that the patient is receiving follow-up care, managing complications, or undergoing rehabilitation related to the original incident.

This code is appropriate for subsequent visits where a patient is being treated for injuries sustained from an explosion on a fishing vessel, such as wound care, physical therapy for blast injuries, or psychological counseling for trauma. It would be used after the initial emergency department visit or hospitalization.

• Always pair this external cause code with an injury code describing the specific nature of the patient's condition.
• Ensure the "D" seventh character is used only for subsequent encounters, not for the initial treatment of the injury.
• Verify that the incident explicitly involved a fishing boat, as other watercraft have different external cause codes.
