Pneumoconiosis due to other specified inorganic dusts

This code signifies a chronic lung disease resulting from the inhalation and retention of inorganic dusts other than silica, asbestos, or talc. It represents a fibrotic reaction in the lungs caused by occupational or environmental exposure to various mineral dusts.

Apply this code when documentation specifies pneumoconiosis caused by inorganic dusts not otherwise classified, such as aluminum, beryllium, or iron (siderosis). Supporting documentation should include a history of exposure to a specific inorganic dust and diagnostic findings consistent with pneumoconiosis.

• Ensure the specific inorganic dust is documented and is not silica, asbestos, or talc, as these have their own specific codes.
• Always sequence this code first if it is the primary reason for the encounter.
• Look for associated respiratory symptoms, imaging findings (e.g., nodular opacities), and occupational history in the medical record.
