ICD-10 Code J68.8 – Other respiratory conditions due to chemicals, gases, fumes and vapors (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J68.8 – Other respiratory conditions due to chemicals, gases, fumes and vapors
What it is
Use this code for respiratory conditions caused by exposure to chemicals, gases, fumes, or vapors that do not fit a more specific diagnosis. It captures lung or airway injury linked to an inhaled irritant.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include cough, wheezing, shortness of breath, throat irritation, or evidence of airway inflammation after exposure.
When to use this code
Use J68.8 when the record links the respiratory condition to a chemical or inhalational exposure and the provider does not name a more specific disorder. It may apply after workplace, household, or environmental exposure. Code the documented condition, not the exposure alone.
Do not use for
Do not use this code for asthma, pneumonia, or clearly specified toxic effects when a more precise diagnosis is documented. If the chart only states exposure without respiratory involvement, check documentation.
Coding tip
Look for provider wording that connects the respiratory problem to the inhaled agent before assigning J68.8.
