What This Code Means

Fluid buildup in the lungs caused by exposure to harmful chemicals, gases, fumes, or vapors, often from workplace or accidental exposure.

Coding Tips

•Always document the specific chemical, gas, fume, or vapor exposure when available to support medical necessity
•Consider using an external cause code (Chapter 20) to identify how the exposure occurred (occupational, accidental, etc.)

Clinical Significance

Chemical-induced pulmonary edema represents severe acute lung injury with fluid flooding the alveoli, often a medical emergency requiring intensive care. This code carries significant risk adjustment weight because it reflects a life-threatening condition with high resource utilization, including potential mechanical ventilation and ICU stay.

Documentation Requirements

✓Identification of the specific chemical, gas, fume, or vapor causing pulmonary edema
✓Chest imaging confirming pulmonary edema pattern
✓Arterial blood gas results showing respiratory compromise
✓Oxygen requirements and ventilatory support details
✓Temporal relationship between chemical exposure and symptom onset
✓External cause codes documenting the circumstances of exposure
✓Clinical differentiation from cardiogenic pulmonary edema

Excludes 1 — Do NOT code together

pulmonary edema (acute) (chronic) NOS (J81.-)

Commonly Confused Codes

J81.0 (Acute pulmonary edema) — non-chemical cause; use J68.1 when chemicals are the documented cause J68.0 (Bronchitis and pneumonitis due to chemicals) — airway inflammation vs. alveolar flooding J80 (Acute respiratory distress syndrome) — ARDS is a specific syndrome; chemical pulmonary edema may progress to ARDS I50.1 (Left ventricular failure) — cardiogenic pulmonary edema has a cardiac cause, not chemical
