Code Classification

  • Diseases of the respiratory system
    (J00–J99)
    • Lung diseases due to external agents
      (J60-J70)
      • Airway disease due to specific organic dust
        (J66)

J66 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of airway disease due to specific organic dust. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Airway disease due to specific organic dust

Non-specific codes like J66 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for airway disease due to specific organic dust:

  • Use J66.0 for Byssinosis - BILLABLE CODE

  • Use J66.1 for Flax-dressers' disease - BILLABLE CODE

  • Use J66.2 for Cannabinosis - BILLABLE CODE

  • Use J66.8 for Airway disease due to other specific organic dusts - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • allergic alveolitis J67
  • asbestosis J61
  • bagassosis J67.1
  • farmer's lung J67.0
  • hypersensitivity pneumonitis due to organic dust J67
  • reactive airways dysfunction syndrome J68.3

Patient Education


Interstitial Lung Diseases

Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. The inflammation and scarring make it hard to get enough oxygen. The scarring is called pulmonary fibrosis.

Breathing in dust or other particles in the air is responsible for some types of interstitial lung diseases. Specific types include:

  • Black lung disease among coal miners, from inhaling coal dust
  • Farmer's lung, from inhaling farm dust
  • Asbestosis, from inhaling asbestos fibers
  • Siderosis, from inhaling iron from mines or welding fumes
  • Silicosis, from inhaling silica dust

Other causes include autoimmune diseases or occupational exposures to molds, gases, or fumes. Some types of interstitial lung disease have no known cause.

Treatment depends on the type of exposure and the stage of the disease. It may involve medicines, oxygen therapy, or a lung transplant in severe cases.
