Aspirat pneumonitis due to anesth during preg, first tri

This code describes inflammation of the lung tissue resulting from the inhalation of gastric contents or other foreign material, specifically occurring due to anesthesia administered during the first trimester of pregnancy. This condition can lead to chemical pneumonitis and secondary bacterial infection.

Assign this code when documentation clearly indicates aspiration pneumonitis developed as a direct complication of anesthesia given to a pregnant patient in her first trimester. Supporting documentation should specify the trimester and the causal link to anesthesia.

• Ensure documentation explicitly links the aspiration pneumonitis to anesthesia and specifies the first trimester.
• Do not use for aspiration pneumonitis unrelated to anesthesia or occurring in other trimesters.
• Code any associated bacterial pneumonia separately, if documented.
