Toxic effect of venom of other reptiles, assault, sequela

This code signifies the long-term or residual effects resulting from a toxic exposure to venom from a reptile other than a snake or lizard, where the exposure was intentionally inflicted by another person. These sequelae can manifest as chronic pain, tissue damage, neurological deficits, or other persistent health issues directly attributable to the original envenomation.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a past assault involving venom from a non-snake/non-lizard reptile. This is appropriate for follow-up visits or when the sequela is the primary reason for the encounter, long after the acute phase of the envenomation has resolved.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to a past assault by reptile venom.
• Verify the reptile involved is not a snake or lizard; otherwise, a different T63.1x code would be more appropriate.
