ICD-10 Code J63.6 – Pneumoconiosis due to other specified inorganic dusts (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J63.6 – Pneumoconiosis due to other specified inorganic dusts
What it is
J63.6 identifies pneumoconiosis caused by inhaling certain inorganic dusts not named in more specific codes. It describes a chronic lung disease from occupational or environmental dust exposure.
Clinical signs
Typical findings include chronic cough, shortness of breath, and evidence of interstitial lung disease or pulmonary fibrosis. Clinical features vary; refer to documentation.
When to use this code
Use J63.6 when the record clearly links pneumoconiosis to exposure to other specified inorganic dusts and no more specific ICD-10 code fits. You may also use it when the clinician documents the dust type and confirms the diagnosis. Check documentation if the exposure is vague or the cause is uncertain.
Do not use for
Do not use this code for pneumoconiosis from coal, asbestos, or silica exposure, which have separate codes. Also avoid it when the diagnosis is only suspected or the dust exposure is not specified.
Coding tip
Code the documented dust exposure first, then confirm J63.6 only when the provider names an appropriate inorganic dust cause.
