Drown due to fall off (nonpowered) inflatable craft, subs

This code describes injuries or conditions resulting from a patient falling off a non-motorized inflatable watercraft, such as a raft or inner tube, and subsequently experiencing drowning or submersion. This specific code is for a subsequent encounter, meaning the patient is receiving follow-up care for an injury that occurred on a previous occasion.

Use this code when a patient presents for ongoing treatment, rehabilitation, or follow-up related to a drowning or submersion incident that happened previously, and the initial event was caused by falling from a non-powered inflatable craft. This would apply to scenarios like follow-up for aspiration pneumonia, neurological deficits, or other complications stemming from the initial near-drowning.

• Always use in conjunction with an external cause code (e.g., W16.-) to fully describe the circumstances of the injury.
• Ensure the encounter is truly "subsequent" and not the initial treatment for the injury.
• Verify the type of watercraft was explicitly non-powered and inflatable to ensure accurate code selection.
