Stannosis

Stannosis is a benign pneumoconiosis resulting from the inhalation of tin dust or its oxides. It is characterized by the accumulation of tin particles in the lungs, which are visible on imaging but typically do not cause significant lung fibrosis or functional impairment. This condition is primarily an occupational lung disease.

This code is used when documentation confirms a diagnosis of stannosis, often identified through occupational history and radiographic findings showing discrete, dense opacities in the lungs. It applies to individuals with chronic exposure to tin dust, such as miners or workers in tin processing industries. Documentation should clearly link the lung findings to tin exposure.

• Ensure documentation specifies "stannosis" and not a general pneumoconiosis, as other specific pneumoconioses have distinct codes.
• Always review the patient's occupational history for exposure to tin dust or fumes.
• Do not confuse with other metal pneumoconioses like siderosis (iron) or berylliosis (beryllium), which have different ICD-10-CM codes.
