ICD-10 Code J92.9 – Pleural plaque without asbestos (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J92.9 – Pleural plaque without asbestos
What it is
This code identifies pleural plaque involving the lining of the lung, without documented asbestos exposure. It is used when the chart notes pleural plaque but does not specify an asbestos-related cause.
Clinical signs
Pleural plaques are often found incidentally on chest imaging and may cause no symptoms. Clinical features vary; refer to documentation for any associated pleural thickening or calcification.
When to use this code
Use J92.9 when the provider documents pleural plaque and explicitly states no asbestos exposure, or the record supports a non-asbestos cause. It also fits incidental imaging findings when the diagnosis is confirmed and no asbestos history is recorded. If the cause is unclear, check documentation before coding.
Do not use for
Do not use this code for asbestos-related pleural plaque or other asbestos diseases. Do not assign it when the finding is better described as pleural effusion, pleural thickening, or another pleural disorder.
Coding tip
Verify whether asbestos exposure is documented; that detail determines the correct code.
