ICD-10 Code J67 – Hypersensitivity pneumonitis due to organic dust (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J67 – Hypersensitivity pneumonitis due to organic dust
What it is
J67 identifies hypersensitivity pneumonitis caused by inhaled organic dusts, such as moldy hay, bird proteins, or similar workplace exposures. Use it when the record documents an immune-mediated lung reaction from organic material.
Clinical signs
Typical findings include cough, shortness of breath, and symptoms that worsen after exposure and improve away from the source. Clinical features vary; refer to documentation for the specific exposure and diagnostic evidence.
When to use this code
Use J67 when the clinician clearly links hypersensitivity pneumonitis to organic dust exposure and does not specify a more detailed subtype. It fits charted occupational, agricultural, or avian exposure histories with compatible lung inflammation. If the note only says interstitial lung disease or pneumonia, check documentation before assigning this code.
Do not use for
Do not use this code for infectious pneumonia, asthma, or nonspecific allergic rhinitis. Do not assign it when organic dust exposure is not documented or when the diagnosis is uncertain.
Coding tip
Confirm both the hypersensitivity pneumonitis diagnosis and the organic dust source in the record before coding J67.
