Drown d/t thrown ovrbrd by motion of power wtrcrft, subs

This code signifies a non-fatal drowning or near-drowning incident that occurred because an individual was ejected from a vessel due to the movement of another motorized watercraft. This specific code is used for follow-up care after the initial injury has been treated.

Apply this code when documenting subsequent medical care for a patient who previously experienced a near-drowning event caused by being thrown from their watercraft due to the wake or impact of another powered vessel. This includes rehabilitation, follow-up appointments, or treatment for lingering complications from the initial incident.

• Ensure the encounter is for follow-up care, not the initial treatment of the injury.
• Verify that the cause of being thrown overboard was explicitly due to the motion of another powered watercraft.
• Always sequence this external cause code after the primary diagnosis describing the drowning or near-drowning condition (e.g., anoxic brain damage, aspiration pneumonia).
