Drown due to being washed overboard from unsp wtrcrft, init

This code signifies an incident where an individual experienced a near-drowning or drowning event after being swept off an unidentifiable water vessel. The "initial encounter" designation indicates that this code is used for the first time a patient is receiving active treatment for injuries sustained from this specific event.

Apply this code when a patient presents for initial treatment following an incident where they were washed overboard from a watercraft whose type is not documented. This includes situations where the patient was rescued but suffered respiratory distress, hypothermia, or other injuries related to submersion. It is appropriate for the initial hospital visit, emergency department encounter, or first outpatient visit for this specific event.

• Ensure documentation clearly states the patient was washed overboard and the type of watercraft is unknown.
• Pair this code with external cause codes (e.g., Y92.838 for other specified water transport accident) to provide a complete picture of the incident.
• Do not use this code for subsequent encounters or for incidents where the type of watercraft is known (e.g., fishing boat, yacht).
