Drown due to fishing boat overturning, subs

This code signifies a patient presenting for follow-up care or complications stemming from a non-fatal drowning or submersion incident that occurred when a fishing boat overturned. The initial injury has already been treated, and the current encounter addresses ongoing issues related to that event.

This code is appropriate for documenting subsequent visits for conditions such as pneumonia, acute respiratory distress syndrome (ARDS), neurological deficits, or psychological sequelae directly resulting from the drowning incident. It is used after the initial treatment of the acute drowning event.

• Ensure the encounter is for follow-up care or complications, not the initial treatment.
• Always sequence this external cause code after the primary diagnosis describing the patient's current condition.
• Verify that the mechanism of injury specifically involves a fishing boat overturning.
