Respiratory conditions due to smoke inhalation

This code signifies acute or chronic respiratory tract damage resulting from the inhalation of smoke particles and hot gases, typically from fires. It encompasses conditions such as tracheobronchitis, pneumonitis, or acute respiratory distress syndrome (ARDS) directly attributable to smoke exposure.

Apply this code when documentation clearly states respiratory symptoms or diagnoses (e.g., cough, wheezing, dyspnea, ARDS, bronchitis) are a direct consequence of smoke inhalation. This is commonly seen in patients exposed to structural fires or wildfires. Supporting documentation should specify the etiology as smoke.

• Differentiate from inhalation of other toxic substances; if chemicals, gases, fumes, or vapors are involved, refer to J68.9.
• Always code the specific respiratory condition (e.g., acute bronchitis, ARDS) as a primary diagnosis if known, with this code as an additional diagnosis to specify etiology.
• Ensure the documentation explicitly links the respiratory condition to "smoke inhalation" and not just "inhalation injury" if other substances were present.
