ICD-10 Code J67.3 – Suberosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J67.3 – Suberosis
What it is
J67.3 identifies suberosis, a hypersensitivity pneumonitis caused by inhaling dust from cork or cork-related organic material. Use it when the record documents an immune reaction linked to this exposure.
Clinical signs
Typical findings include cough, shortness of breath, and other respiratory symptoms after cork dust exposure. Clinical features vary; refer to documentation for the specific presentation and supporting diagnosis.
When to use this code
Use J67.3 when the provider links the patient’s interstitial lung disease or hypersensitivity pneumonitis to cork dust or similar organic exposure. It is appropriate when suberosis is explicitly documented, even if symptoms are described broadly.
If the chart only mentions respiratory complaints without the exposure-related diagnosis, check documentation before assigning this code. Make sure the record supports the environmental cause, not just a nonspecific pneumonitis.
Do not use for
Do not use this code for asthma, infection, or other lung disease unrelated to cork exposure. Also avoid it when the note does not clearly document suberosis or a hypersensitivity reaction.
Coding tip
Look for the exposure source in the assessment or history; the diagnosis should connect symptoms to cork dust or related material.
