Valid for Submission
J68.4 is a billable diagnosis code used to specify a medical diagnosis of chronic respiratory conditions due to chemicals, gases, fumes and vapors. The code J68.4 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code J68.4 might also be used to specify conditions or terms like chronic chemical respiratory disease, chronic emphysema due to chemical fumes, chronic pulmonary fibrosis due to chemical fumes, diffuse interstitial pulmonary fibrosis, drug-induced bronchiolitis obliterans , drug-induced pneumonitis, etc.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code J68.4:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Emphysema (diffuse) (chronic) due to inhalation of chemicals, gases, fumes and vapors
- Obliterative bronchiolitis (chronic) (subacute) due to inhalation of chemicals, gases, fumes and vapors
- Pulmonary fibrosis (chronic) due to inhalation of chemicals, gases, fumes and vapors
Type 1 ExcludesType 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.

Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code J68.4 are found in the index:
- - Bronchiolitis (acute) (infective) (subacute) - J21.9
- - chemical (chronic) - J68.4
- - obliterative (chronic) (subacute) - J44.9
- - due to fumes or vapors - J68.4
- - due to chemicals, gases, fumes or vapors (inhalation) - J68.4
- - Bronchitis (diffuse) (fibrinous) (hypostatic) (infective) (membranous) - J40
- - Disease, diseased - See Also: Syndrome;
- - Emphysema (atrophic) (bullous) (chronic) (interlobular) (lung) (obstructive) (pulmonary) (senile) (vesicular) - J43.9
- - due to chemicals, gases, fumes or vapors - J68.4
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Chronic chemical respiratory disease
- Chronic emphysema due to chemical fumes
- Chronic pulmonary fibrosis due to chemical fumes
- Diffuse interstitial pulmonary fibrosis
- Drug-induced bronchiolitis obliterans
- Drug-induced pneumonitis
- Toxic bronchiolitis obliterans
- Toxic diffuse interstitial pulmonary fibrosis
- Toxic emphysema
- Toxic pneumonitis

Information for Patients
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.
