Pneumoconiosis due to asbestos and other mineral fibers

This code represents a chronic lung disease caused by the inhalation and retention of asbestos fibers or other mineral dusts, leading to interstitial fibrosis. It specifically refers to the fibrotic changes in the lung parenchyma resulting from this exposure.

Use this code when documentation confirms a diagnosis of pneumoconiosis directly attributed to asbestos or other mineral fiber exposure. This diagnosis is typically supported by a history of occupational exposure, characteristic imaging findings (e.g., interstitial fibrosis, honeycombing), and pulmonary function test abnormalities.

• Differentiate from pleural plaques (J92.0), which are distinct and not coded with this diagnosis.
• Ensure documentation clearly specifies the causative agent as asbestos or other mineral fibers.
• Do not code with J65 if tuberculosis is also present; refer to the Excludes1 note.
