Toxic effect of rattlesnake venom, assault, sequela

This code signifies a long-term health problem or complication resulting from a rattlesnake envenomation that occurred due to an intentional act of harm by another person. It indicates that the acute phase of the venom's toxic effect has passed, but residual issues persist. These sequelae could include chronic pain, tissue damage, neurological deficits, or other lasting impairments.

Use this code when documenting a patient presenting with a current condition that is a direct consequence of a rattlesnake bite inflicted as an assault in the past. This applies when the patient is no longer in the acute treatment phase for the envenomation itself, but is being treated for the chronic or residual effects. Examples include follow-up for nerve damage, scar tissue management, or ongoing functional limitations.

• This code is for sequelae only; do not use for the initial acute toxic effect or subsequent encounters for acute treatment.
• Always code the specific nature of the sequela (e.g., chronic pain, paralysis) in addition to this code.
• Ensure documentation clearly links the current condition to a past rattlesnake envenomation that was an assault.
