About coding aspiration pneumonitis

The ICD-10-CM code for aspiration pneumonitis is J69.0 (Pneumonitis due to inhalation of food and vomit). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J69.0.

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

Don't report J69.0 together with the conditions in its Excludes1 note: chemical pneumonitis due to anesthesia (J95.4) and obstetric aspiration pneumonitis (O74.0).

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.
