Drown due to passenger ship overturning, subs

This code signifies an injury or adverse health effect resulting from a drowning or near-drowning incident that occurred due to a passenger ship capsizing. It is specifically used for follow-up care, rehabilitation, or complications arising after the initial treatment of the event.

Apply this code for subsequent encounters when a patient is receiving ongoing care for conditions such as aspiration pneumonia, hypoxic brain injury, or psychological trauma directly attributable to a drowning event caused by a passenger ship overturning. This includes follow-up visits, physical therapy, or mental health services related to the incident.

• Requires an external cause code (V90.01) as the primary external cause.
• Always assign additional codes for the specific injuries or conditions resulting from the drowning.
• Ensure the "D" seventh character is used only for subsequent encounters, not initial treatment.
