Drown due to unsp watercraft overturning, subs

This code indicates an injury or adverse health effect resulting from a near-drowning or drowning incident where an unspecified watercraft overturned. The "subsequent encounter" designation means the patient is receiving follow-up care for the initial injury, such as rehabilitation, wound care, or management of long-term complications.

Apply this code when a patient presents for ongoing treatment related to a drowning or near-drowning event caused by an unknown type of watercraft capsizing. This would include scenarios like a patient returning for pulmonary therapy after aspirating water, or for neurological rehabilitation following an anoxic brain injury sustained during the incident.

• Ensure documentation clearly states the patient is receiving follow-up care for the initial drowning event.
• Confirm the cause was an unspecified watercraft overturning; if the type of watercraft is known, a more specific code should be used.
• Always code any associated injuries or conditions, such as aspiration pneumonia or anoxic brain injury, in addition to this external cause code.
