Aspirat pneumonitis due to anesth during preg, third tri

This code describes inflammation of the lungs caused by inhaling foreign material, specifically gastric contents or other substances, during the administration of anesthesia to a pregnant patient in her third trimester. This aspiration leads to a chemical pneumonitis, distinct from bacterial pneumonia.

Use this code when documentation clearly indicates aspiration pneumonitis occurred as a direct complication of anesthesia administered during the third trimester of pregnancy. Supporting documentation would include operative reports, anesthesia records, and physician notes detailing the aspiration event and subsequent lung inflammation.

• Ensure the documentation specifies the aspiration occurred during anesthesia, not post-operatively or from other causes.
• Verify the pregnancy stage is explicitly stated as the third trimester.
• Do not confuse with aspiration pneumonia (J69.0), which implies an infectious process, unless bacterial infection is also documented.
