Intentional self-harm by drown in natural water, sequela

This code describes the long-term effects or complications arising from a deliberate act of self-harm through drowning or submersion in a natural body of water (e.g., ocean, lake, river). These sequelae can include chronic respiratory issues, neurological damage due to anoxic brain injury, or psychological conditions stemming from the event.

Use this code when documenting conditions that are a direct consequence of a past intentional self-harm attempt by drowning or submersion in natural water. This applies to follow-up encounters where the primary injury has healed, but residual effects persist. It should be assigned as a secondary diagnosis to specify the etiology of the current sequela.

• Always sequence this code after the code for the specific sequela (e.g., anoxic brain damage, chronic respiratory failure).
• Ensure documentation clearly links the current condition to the past intentional self-harm event by drowning in natural water.
• Do not use this code for the initial acute injury; it is exclusively for sequelae.
