Assault by drowning and submersion in natural water, subs

This code signifies an injury sustained from an intentional act of drowning or submersion in a natural body of water (e.g., lake, river, ocean) where the patient is receiving follow-up care for the initial injury. It indicates that the patient is in the healing phase and is no longer in the acute phase of treatment for the assault.

Use this code for subsequent encounters when a patient is being treated for complications, sequelae, or ongoing management related to an assault by drowning or submersion in natural water. This includes follow-up appointments for respiratory issues, neurological damage, or psychological trauma resulting from the initial event.

• Ensure the documentation clearly states the injury was due to an assault and occurred in a natural water environment.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always code the specific injuries sustained (e.g., anoxic brain injury, aspiration pneumonia) in addition to this external cause code.
