ICD-10 Code J63 – Pneumoconiosis due to other inorganic dusts (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J63 – Pneumoconiosis due to other inorganic dusts
What it is
J63 identifies pneumoconiosis caused by inhaling inorganic dusts other than the classic coal, silica, or asbestos exposures. It is a chronic occupational lung disease that develops after long-term dust exposure.
Clinical signs
Typical findings include chronic cough, shortness of breath, and reduced exercise tolerance. Imaging and occupational history help support the diagnosis; clinical features vary, so refer to documentation.
When to use this code
Use J63 when the provider documents pneumoconiosis from other inorganic dust exposure and does not specify a more exact dust-related code. It fits cases where the record links chronic lung disease to workplace or environmental dust inhalation. Check documentation for the named dust source.
Do not use for
Do not use J63 for pneumoconiosis due to coal, silica, or asbestos, which have separate codes. Avoid assigning it when the diagnosis is only suspected or when another lung disorder better explains the findings.
Coding tip
Confirm the exact dust exposure and the provider’s final diagnosis before coding.
