About J69.1

J69.1 is the ICD-10-CM diagnosis code for pneumonitis due to inhalation of oils and essences. It belongs to category J69 (pneumonitis due to solids and liquids), block J60-J70 (lung diseases due to external agents) and chapter 10 (diseases of the respiratory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within J69 (pneumonitis due to solids and liquids), J69.1 is specifically for pneumonitis due to inhalation of oils and essences. Related codes cover food and vomit (J69.0) and other solids and liquids (J69.8).

Don't report J69.1 together with the conditions in its Excludes1 note: endogenous lipoid pneumonia (J84.89).

Code first: (T51-T65) to identify substance.

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 177 (Respiratory Infections and Inflammations with MCC, relative weight 1.6092), DRG 178 (Respiratory Infections and Inflammations with CC, relative weight 0.9744) and DRG 179 (Respiratory Infections and Inflammations without CC/MCC, relative weight 0.7345), in MDC 04 (Diseases and Disorders of the Respiratory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 507.1 (pneumonitis due to inhalation of oils and essences).
