Drown due to being washed overboard from water-skis, subs

This code signifies an injury resulting from a near-drowning or drowning event that occurred because an individual was thrown or swept off water skis into the water. It specifically indicates that this is not the initial presentation for this particular incident, but rather a follow-up visit or subsequent care related to the original event.

Use this code for any subsequent medical encounters, such as follow-up appointments, rehabilitation sessions, or ongoing treatment, for a patient who previously experienced a drowning or near-drowning incident due to being washed overboard from water skis. This applies after the initial acute care for the event has been rendered.

• Always ensure documentation clearly states the patient was washed overboard from water skis as the cause of the drowning/submersion.
• Verify that the encounter is for follow-up care or sequelae, not the initial treatment, to justify the "D" (subsequent encounter) seventh character.
• Code any specific injuries or conditions resulting from the drowning (e.g., aspiration pneumonia, anoxic brain injury) in addition to this external cause code.
