Pneumonitis due to inhalation of other solids and liquids

This code represents inflammation of the lung tissue resulting from the aspiration or inhalation of foreign solid or liquid substances, excluding food or vomitus. It describes a non-infectious pulmonary response to irritants that have entered the respiratory tract.

Use this code when documentation specifies pneumonitis caused by inhaling substances such as chemicals, oils, dusts, or other non-food/non-vomitus materials. This is appropriate for cases like aspiration of petroleum products, mineral oil, or other non-gastric fluids.

• Differentiate from aspiration pneumonitis due to food or vomitus (J69.0), which is a common miscoding.
• Ensure documentation clearly identifies the inhaled substance as a "solid" or "liquid" other than food or gastric contents.
• Consider an external cause code (V00-Y99) to describe the circumstances of the inhalation, if known and documented.
