Exposure to smoke, fire and flames, undet intent, sequela

This code signifies a long-term or late-onset health condition resulting from an exposure to smoke, fire, or flames where the intent of the exposure (accidental, self-harm, assault) cannot be determined. This sequela could manifest as chronic respiratory issues, scar tissue complications, or psychological trauma years after the initial incident.

Apply this code when documenting a current health problem directly attributable to a past exposure to smoke, fire, or flames, and the medical record explicitly states that the intent of the original exposure is unknown or undetermined. This is appropriate for follow-up visits addressing the lasting effects of such an event.

• Always use in conjunction with a code describing the specific sequela (e.g., chronic bronchitis, hypertrophic scar).
• Ensure documentation clearly links the current condition to a past exposure and explicitly states "undetermined intent."
• This code is for the sequela of the exposure, not the initial acute injury.
