Drown due to passenger ship overturning, sequela

This code signifies a long-term health condition or complication arising from a past drowning or near-drowning incident that occurred due to a passenger ship capsizing. It indicates that the patient is presenting for treatment of a residual effect directly attributable to that specific event.

Use this code when documenting the sequelae of a drowning or submersion injury that was caused by a passenger ship overturning. This applies to follow-up visits or ongoing treatment for conditions such as anoxic brain injury, chronic respiratory issues, or neurological deficits stemming from the original incident.

• Requires a seventh character "S" to indicate sequela, meaning the patient is being seen for a late effect of the initial injury.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., G93.1 for anoxic brain damage).
• Ensure documentation clearly links the current condition to the past drowning event and specifies the cause as a passenger ship overturning.
