ICD-10 Code J62.8 – Pneumoconiosis due to other dust containing silica (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J62.8 – Pneumoconiosis due to other dust containing silica
What it is
J62.8 identifies pneumoconiosis caused by inhaling dusts that contain silica but are not classified as pure silicosis. Use it for chronic lung disease from occupational or environmental exposure to mixed silica-containing dust.
Clinical signs
Clinical features vary; refer to documentation. Common findings include chronic cough, shortness of breath, and imaging evidence of interstitial lung disease or fibrotic changes consistent with dust-related lung injury.
When to use this code
Use J62.8 when the provider documents pneumoconiosis due to dust containing silica, especially in workers with relevant exposure history. Choose it when the record does not support a more specific pneumoconiosis code such as silicosis.
It may also fit cases described as mixed-dust pneumoconiosis with silica exposure. Check documentation for the exact dust type and whether the condition is occupationally related.
Do not use for
Do not use this code for uncomplicated silicosis or for pneumoconiosis caused by non-silica dusts. If the chart only says “lung disease” or exposure without a confirmed diagnosis, check documentation.
Coding tip
Confirm both the pneumoconiosis diagnosis and the silica-containing dust exposure before assigning J62.8.
