Pulmonary edema due to chemicals, gases, fumes and vapors

This code represents the accumulation of fluid in the lungs resulting from exposure to toxic chemical substances, gases, fumes, or vapors. This condition impairs gas exchange and can lead to respiratory distress. It specifically identifies pulmonary edema caused by an inhaled irritant rather than other etiologies.

Use this code when documentation clearly indicates pulmonary edema as a direct consequence of exposure to chemical agents, such as industrial fumes, cleaning product vapors, or toxic gases. The patient's history should detail the specific exposure event and the subsequent development of respiratory symptoms and radiographic findings consistent with pulmonary edema.

• Ensure the documentation explicitly links the pulmonary edema to chemical, gas, fume, or vapor exposure.
• Do not use this code if the pulmonary edema is due to cardiac causes, renal failure, or other non-chemical etiologies.
• Consider an external cause code (e.g., T59.-) to identify the specific toxic substance if known and documented.
