Coalworker's pneumoconiosis

This code represents a chronic lung disease caused by the inhalation and retention of coal dust in the lungs, leading to inflammation and fibrosis. It is a form of occupational lung disease, specifically pneumoconiosis, affecting individuals working in coal mining or related industries.

Use this code when documentation clearly indicates a diagnosis of coalworker's pneumoconiosis, often supported by a history of coal dust exposure, characteristic chest imaging findings (e.g., small, rounded opacities), and pulmonary function test abnormalities. This diagnosis is typically made by an occupational medicine specialist or pulmonologist.

• Do not code this condition with J65 if tuberculosis is also present; refer to the Excludes1 note.
• Always review the patient's occupational history for confirmation of coal dust exposure.
• Consider additional codes for any associated complications or manifestations, such as cor pulmonale or respiratory failure.
