ICD-10 Code J70.5 – Respiratory conditions due to smoke inhalation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J70.5 – Respiratory conditions due to smoke inhalation
What it is
J70.5 identifies respiratory problems caused by inhaling smoke, usually after exposure to a fire. Use it when the record links the lung or airway condition directly to smoke inhalation.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include cough, throat or airway irritation, shortness of breath, wheezing, hoarseness, or evidence of inhalation injury after smoke exposure.
When to use this code
Use this code when the provider documents a respiratory condition due to smoke inhalation, such as airway irritation or inhalation injury from a fire. It fits cases where the smoke exposure is the stated cause. If the chart only notes smoke exposure without a respiratory diagnosis, check documentation.
Do not use for
Do not use J70.5 for burns without respiratory involvement or for general fire exposure alone. If the condition is due to a different inhaled substance, select the more specific code and check documentation.
Coding tip
Link the respiratory diagnosis to smoke inhalation in the note before assigning J70.5.
