Toxic effect of rattlesnake venom, accidental, sequela

This code signifies a long-term complication or late effect resulting from an accidental rattlesnake envenomation. It is used when the acute toxic effects have resolved, but the patient continues to experience residual health problems directly attributable to the venom. These sequelae can include chronic pain, tissue damage, neurological deficits, or other persistent issues.

Apply this code when documenting a patient encounter for a condition that is a direct consequence of a rattlesnake bite that occurred in the past. This would be used for follow-up visits addressing chronic issues like scar tissue, nerve damage, or persistent functional limitations stemming from the original envenomation. Do not use this code for the initial acute treatment of the bite itself.

• Always sequence this sequela code after the code for the specific residual condition (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to the past rattlesnake bite.
• This code indicates an "accidental" exposure; verify the circumstances of the bite from the medical record.
