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

This code signifies a patient's exposure to smoke from a controlled outdoor fire, such as a bonfire or burn pile, where the fire was not within a building or structure. It indicates that the patient is presenting for follow-up care related to this specific exposure, rather than the initial visit. The exposure is considered non-accidental and managed.

Apply this code when a patient seeks subsequent medical attention for symptoms or conditions (e.g., respiratory irritation, eye irritation) resulting from smoke exposure during a controlled outdoor burn. This would include follow-up visits for persistent cough, asthma exacerbation, or other delayed reactions after the initial assessment.

• Ensure the encounter is for follow-up care; use the initial encounter code for the first visit.
• Verify the fire was controlled and not within a building or structure to differentiate from other smoke exposure codes.
• Always code any associated symptoms or conditions resulting from the smoke exposure in addition to this external cause code.
