Explosion on board unspecified watercraft, initial encounter

This code signifies an injury or adverse health effect sustained by an individual due to an explosion occurring on any type of watercraft where the specific vessel type is not documented. It indicates the very first time the patient is receiving care for this particular incident.

Apply this code when a patient presents with injuries directly resulting from an explosion on a boat, ship, or other water-based vehicle, and the medical record does not specify the exact type of watercraft involved. This is appropriate for the initial visit or encounter for treatment of these injuries.

• Ensure "unspecified watercraft" is explicitly or implicitly documented when the specific vessel is unknown.
• Only use the "A" (initial encounter) seventh character for the first time the patient is seen for this injury.
• Do not use if the explosion occurred on land or a specified type of watercraft (e.g., military ship, fishing boat).
