ICD-10 Code J69.1 – Pneumonitis due to inhalation of oils and essences (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J69.1 – Pneumonitis due to inhalation of oils and essences
What it is
J69.1 identifies pneumonitis caused by inhaling oils or aromatic essences. Use it when documentation shows aspiration or inhalation-related lung inflammation from these substances.
Clinical signs
Patients may have cough, shortness of breath, chest discomfort, or abnormal lung findings after exposure. Clinical features vary; refer to documentation.
When to use this code
Use J69.1 when the record clearly links pneumonitis to inhaled oils, essential oils, or similar essences. It is appropriate for aspiration-related lung inflammation documented by the clinician, even if the exact product name is given instead of the general term.
Do not use for
Do not use this code for ordinary pneumonia without a documented inhalation cause. If the chart does not support oil or essence exposure, check documentation.
Coding tip
Code the condition only when the inhaled substance and resulting pneumonitis are both documented.
