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

This code signifies a health condition or complication arising from a past exposure to smoke from a controlled fire that occurred outdoors, not within a building. It indicates that the effects of this smoke exposure are long-term or delayed, rather than acute.

Apply this code when documenting a patient presenting with respiratory issues, chronic cough, or other persistent health problems directly attributable to a previous incident of smoke inhalation from an outdoor, controlled burn. This is appropriate for conditions diagnosed after the initial acute phase of exposure has passed.

• Always use in conjunction with a code identifying the specific sequela (e.g., chronic bronchitis, asthma exacerbation).
• Ensure the documentation clearly links the current condition to a past exposure to smoke from an outdoor, controlled fire.
• Verify the fire was indeed "controlled" and "not in a building or structure" to differentiate from other smoke exposure codes.
