ICD-10 Code J63.5 – Stannosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J63.5 – Stannosis
What it is
Stannosis is a pneumoconiosis caused by inhalation of tin dust or fumes. It refers to lung changes from occupational exposure, usually in industrial or mining settings.
Clinical signs
Clinical features vary; refer to documentation. Commonly, patients may have cough, shortness of breath, or abnormal chest imaging consistent with dust-related lung disease.
When to use this code
Use J63.5 when the provider documents stannosis, tin pneumoconiosis, or lung disease attributed to tin exposure. This code fits confirmed occupational exposure with respiratory findings or imaging support. Code the documented condition, not exposure alone, unless the record clearly links them.
Do not use for
Do not use this code for nonspecific cough, asthma, or other lung diseases without documented tin-related pneumoconiosis. Check documentation if the record mentions metal exposure but does not identify stannosis.
Coding tip
Verify that the provider explicitly connects tin exposure to the lung diagnosis before assigning J63.5.
