Drown due to unsp watercraft overturning, sequela

This code signifies the long-term or residual effects resulting from a drowning or near-drowning incident that occurred due to an unspecified watercraft capsizing. These sequelae can include chronic respiratory issues, neurological deficits, or other persistent health problems directly attributable to the initial hypoxic event.

Apply this code when documenting conditions that are a direct consequence of a past drowning or near-drowning incident caused by an unknown type of watercraft overturning. This is appropriate for follow-up care and management of chronic conditions stemming from such an event, after the acute phase has passed.

• Always use a secondary code to specify the exact nature of the sequela (e.g., chronic anoxic encephalopathy, aspiration pneumonia).
• Ensure documentation clearly links the current condition to the past drowning event and specifies an "unspecified watercraft" as the cause of the overturning.
• This code is for sequelae only; do not use for acute drowning events.
