Toxic effect of venom of reptiles, self-harm, sequela

This code describes the long-term or residual effects resulting from an intentional act of self-harm involving venom from a reptile other than a snake or lizard. This could include venom from a tuatara or crocodilian, for example, where the individual deliberately exposed themselves to the venom with the intent to cause harm. The sequela could manifest as chronic pain, organ damage, neurological deficits, or other lasting health issues.

Use this code when documenting a patient presenting with a current health problem or condition that is a direct consequence of a past, intentional self-inflicted envenomation by a non-snake/non-lizard reptile. This code is appropriate for follow-up encounters after the acute phase of the self-harm event has passed, and the patient is being treated for the lasting effects. It should be assigned as a secondary diagnosis, following the code for the specific sequela.

• Always assign a code for the specific sequela (e.g., chronic pain, organ damage) as the primary diagnosis, followed by this code.
• Ensure documentation clearly indicates the intentional self-harm nature of the original event and that the reptile was not a snake or lizard.
• This "S" code indicates a sequela and should only be used for the residual effects, not for the initial acute poisoning.
