Exposure to smoke in controlled fire in bldg, sequela

This code signifies a health condition or symptom that is a direct consequence of past exposure to smoke from a controlled fire within a building or structure. It indicates that the initial injury or event has resolved, but a lasting effect or complication remains.

Apply this code when documenting a chronic respiratory condition, persistent neurological deficit, or other long-term health issue that is definitively linked to a previous smoke exposure from a controlled indoor fire. This would include situations where a patient presents with sequelae years after the initial incident.

• Ensure the medical record clearly documents the causal link between the current condition and the past smoke exposure from a controlled indoor fire.
• Always sequence this sequela code after the code for the specific residual condition (e.g., chronic bronchitis, asthma).
• The "S" in the 7th character indicates sequela and should only be used for conditions that are a late effect of the initial exposure.
