Aspirat pneumonitis due to anesth during preg, second tri

This code signifies inflammation of the lungs caused by the inhalation of gastric contents or other foreign material into the respiratory tract, specifically occurring as a complication of anesthesia administered during the second trimester of pregnancy. This aspiration leads to a chemical pneumonitis, distinct from bacterial pneumonia.

Apply this code when documentation clearly indicates aspiration pneumonitis as a direct result of anesthesia given to a pregnant patient during her second trimester. This diagnosis requires a causal link between the anesthetic event and the subsequent lung inflammation.

• Always confirm the trimester of pregnancy documented to ensure accurate code selection.
• Distinguish aspiration pneumonitis from bacterial pneumonia; the etiology is crucial for correct coding.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is the obstetric condition requiring anesthesia.
