Exposure to smoke in uncontrolled fire, not in bldg, sequela

This code signifies a long-term health condition or complication resulting from exposure to smoke from an uncontrolled fire that occurred outdoors, not within a building or other constructed enclosure. It indicates that the patient is presenting for treatment of a sequela, meaning the acute injury or event has passed, and they are now dealing with its lasting effects.

Use this code when documenting conditions such as chronic respiratory issues (e.g., asthma exacerbation, chronic bronchitis), persistent eye irritation, or skin conditions that are directly attributable to smoke inhalation from an outdoor fire. This applies to follow-up visits or ongoing management of these conditions, where the original exposure event is no longer acute.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past smoke exposure from an uncontrolled outdoor fire.
• The "S" in the 7th character indicates sequela; do not use this code for acute exposure.
