Unspecified pneumoconiosis

This code represents a chronic lung disease caused by the inhalation and retention of dust in the lungs, leading to fibrotic changes, when the specific type of dust or causative agent is not documented or identified. It signifies a general diagnosis of dust-induced lung disease without further specification.

Use this code when medical record documentation confirms a diagnosis of pneumoconiosis, but the specific type (e.g., silicosis, asbestosis, coal worker's pneumoconiosis) is not specified by the provider. This code is appropriate when the etiology of the dust exposure is unknown or not clearly documented.

• Avoid using this code if a more specific type of pneumoconiosis is documented; always query the provider for specificity if possible.
• Ensure documentation clearly states "pneumoconiosis" without further detail to support this unspecified code.
• Remember the Excludes1 note: never code this with J65 (pneumoconiosis with tuberculosis).
