What This Code Means

Inflammation of the airways and lung tissue caused by inhaling toxic chemicals, gases, fumes, or vapors in occupational or environmental settings.

Coding Tips

  • Document the specific chemical, gas, fume, or vapor exposure when available
  • Distinguish between acute exposure (single incident) and chronic exposure (repeated)

Clinical Significance

Chemical bronchitis and pneumonitis represents acute inflammatory damage to the airways and lung parenchyma from toxic inhalation, which can be life-threatening and requires aggressive treatment. This code is significant for risk adjustment as it captures serious acute lung injury that may progress to chronic respiratory disease and generate substantial healthcare costs.

Documentation Requirements

  • Identification of the specific chemical, gas, fume, or vapor causing the condition
  • Circumstances of exposure (occupational accident, industrial spill, household accident)
  • Acute onset and temporal relationship to exposure
  • Chest imaging findings
  • Arterial blood gas results and oxygen requirements
  • Treatment provided (bronchodilators, corticosteroids, supplemental oxygen, ventilatory support)
  • External cause codes documenting how the exposure occurred
