Avalanche, landslide, or mudslide, sequela

This code signifies a long-term health condition or complication resulting from a past exposure to an avalanche, landslide, or mudslide. It is used when the direct effects of the natural disaster have resolved, but residual health issues persist. These sequelae can range from chronic pain and neurological deficits to psychological trauma.

Apply this code when documenting a patient's current medical condition that is directly attributable to a past avalanche, landslide, or mudslide event. This is appropriate for follow-up visits addressing chronic injuries, mental health disorders, or other lasting health impacts stemming from the disaster. Do not use for acute injuries sustained during the initial event.

• Always use in conjunction with a code describing the specific sequela (e.g., chronic pain, PTSD, neurological damage).
• Ensure documentation clearly links the current condition to the past avalanche, landslide, or mudslide.
• The "S" in the 7th character indicates sequela and is mandatory for this code.
