ICD-10 Code J67.8 – Hypersensitivity pneumonitis due to other organic dusts (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J67.8 – Hypersensitivity pneumonitis due to other organic dusts
What it is
J67.8 identifies hypersensitivity pneumonitis caused by inhaling organic dusts other than the specific exposures named in more detailed codes. It reflects an immune-mediated lung reaction after repeated exposure.
Clinical signs
Patients may have cough, shortness of breath, and sometimes fever or malaise after exposure. Clinical features vary; refer to documentation and supporting exposure history, imaging, or pulmonary evaluation.
When to use this code
Use J67.8 when the clinician documents hypersensitivity pneumonitis linked to an organic dust exposure that is not otherwise specified in a more exact code. It fits cases such as occupational or environmental exposure where the source is described only generally. Check documentation if the trigger is unclear.
Do not use for
Do not use this code for hypersensitivity pneumonitis with a more specific documented cause, or when the diagnosis is another lung disease. Do not assign it from exposure alone without a documented diagnosis.
Coding tip
Confirm both the diagnosis and the documented organic dust exposure before coding, and choose a more specific J67 code if the source is named.
