Other contact with hot air and other hot gases, sequela

This code describes the long-term effects or complications arising from a past exposure to hot air or other hot gases. It indicates that the initial injury has resolved, but residual issues persist as a direct result of that thermal exposure. These sequelae can manifest in various body systems depending on the original injury site and severity.

Apply this code when documenting conditions such as chronic respiratory issues (e.g., asthma, bronchitis) or scarring of the airways that are definitively linked to a previous inhalation injury from hot air or gases. It is also appropriate for persistent skin changes, such as hypertrophic scars or contractures, resulting from a past thermal burn caused by hot air or gas. This code is used after the acute phase of the injury has passed and the patient is being treated for the lasting consequences.

• Always sequence this sequela code after the code describing the specific nature of the sequela (e.g., a code for chronic bronchitis).
• Ensure documentation clearly links the current condition to a past exposure to hot air or gases.
• Do not use this code for acute injuries; it is exclusively for residual conditions.
