Graphite fibrosis (of lung)

This code represents a chronic interstitial lung disease caused by the inhalation of graphite dust, leading to progressive scarring and stiffening of the lung tissue. It is a form of pneumoconiosis, specifically characterized by fibrotic changes in the lungs due to graphite exposure. Patients typically experience respiratory symptoms such as shortness of breath and cough.

Assign this code for patients diagnosed with lung fibrosis directly attributed to occupational or environmental exposure to graphite. Documentation should clearly state "graphite fibrosis," "graphite pneumoconiosis," or explicitly link lung fibrosis to graphite inhalation. This code is appropriate when the etiology of the fibrosis is confirmed as graphite.

• Ensure documentation specifies graphite as the causative agent for the lung fibrosis, differentiating it from other pneumoconioses.
• Consider additional codes for associated respiratory symptoms (e.g., dyspnea, chronic cough) if separately documented and treated.
• Do not confuse with silicosis or coal worker's pneumoconiosis; these have distinct ICD-10-CM codes.
