Drown d/t being washed ovrbrd from oth power wtrcrft, sqla

This code signifies the long-term or residual effects resulting from a drowning or near-drowning incident where the individual was swept off another type of powered watercraft. These sequelae can encompass a range of conditions, from neurological damage and respiratory complications to psychological trauma, that manifest after the initial acute event.

Use this code when documenting chronic conditions or lasting impairments directly attributable to a past drowning or submersion event that occurred after being washed overboard from a powered vessel other than a ship, sailboat, or houseboat. This applies to follow-up care for patients experiencing ongoing health issues stemming from such an incident.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., anoxic brain damage, aspiration pneumonia, PTSD).
• Ensure documentation clearly links the current condition to the past drowning event and specifies the "washed overboard from other powered watercraft" mechanism.
• Verify that the encounter is for the sequela of the drowning, not the acute drowning event itself, which would use an acute injury code.
