Pneumonitis due to inhalation of oils and essences

This code describes inflammation of the lung tissue resulting from the aspiration or inhalation of oily substances or essential oils. This condition, often referred to as lipoid pneumonia, can lead to chronic inflammation and fibrosis if not identified and managed.

Use this code for patients presenting with respiratory symptoms (e.g., cough, dyspnea) and imaging findings consistent with pneumonitis, where a history of inhaling or aspirating oils (e.g., mineral oil, laxatives, essential oils, petroleum products) is documented. Documentation should clearly link the lung inflammation to the inhalation of these specific substances.

• Differentiate from aspiration pneumonitis due to other substances (e.g., gastric contents), which would be coded elsewhere.
• Ensure the medical record specifies "oils and essences" as the causative agent, not just general aspiration.
• Consider additional codes for any associated complications, such as respiratory failure.
