Code Classification

  • Diseases of the respiratory system
    (J00–J99)
    • Other respiratory diseases principally affecting the interstitium
      (J80-J84)
      • Other interstitial pulmonary diseases
        (J84)

J84 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other interstitial pulmonary diseases. 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 Other interstitial pulmonary diseases

Non-specific codes like J84 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 other interstitial pulmonary diseases:

  • J84.0 for Alveolar and parieto-alveolar conditions - NON-BILLABLE CODE

  • Use J84.01 for Alveolar proteinosis - BILLABLE CODE

  • Use J84.02 for Pulmonary alveolar microlithiasis - BILLABLE CODE

  • Use J84.03 for Idiopathic pulmonary hemosiderosis - BILLABLE CODE

  • Use J84.09 for Other alveolar and parieto-alveolar conditions - BILLABLE CODE

  • J84.1 for Other interstitial pulmonary diseases with fibrosis - NON-BILLABLE CODE

  • Use J84.10 for Pulmonary fibrosis, unspecified - BILLABLE CODE

  • J84.11 for Idiopathic interstitial pneumonia - NON-BILLABLE CODE

  • J84.17 for Other interstitial pulmonary diseases with fibrosis in diseases classified elsewhere - NON-BILLABLE CODE

  • Use J84.2 for Lymphoid interstitial pneumonia - BILLABLE CODE

  • J84.8 for Other specified interstitial pulmonary diseases - NON-BILLABLE CODE

  • Use J84.81 for Lymphangioleiomyomatosis - BILLABLE CODE

  • Use J84.82 for Adult pulmonary Langerhans cell histiocytosis - BILLABLE CODE

  • Use J84.83 for Surfactant mutations of the lung - BILLABLE CODE

  • J84.84 for Other interstitial lung diseases of childhood - NON-BILLABLE CODE

  • Use J84.89 for Other specified interstitial pulmonary diseases - BILLABLE CODE

  • Use J84.9 for Interstitial pulmonary disease, unspecified - 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 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • drug-induced interstitial lung disorders J70.2 J70.4
  • interstitial emphysema J98.2

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.
  • lung diseases due to external agents J60 J70

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.
