Other specified alveolar and parietoalveolar pneumonopathies

This code signifies a diagnosis of lung conditions affecting the alveoli and/or the alveolar walls that are not classified elsewhere. It encompasses a range of non-specific inflammatory or structural abnormalities within these pulmonary regions. These conditions often present with respiratory symptoms like cough, dyspnea, and abnormal imaging findings.

Use this code when documentation specifies a pneumonopathy primarily affecting the alveolar or parietoalveolar structures, but a more specific ICD-9-CM code is unavailable. This includes conditions such as alveolar proteinosis, pulmonary alveolar microlithiasis, or other rare or ill-defined alveolar diseases. Supporting documentation should clearly state the alveolar involvement and rule out more specific forms of pneumonia or interstitial lung disease.

• Ensure documentation explicitly states "other specified" or provides a specific diagnosis that doesn't have its own unique ICD-9-CM code within the pneumonopathy category.
• Avoid using this code if a more specific diagnosis, such as a particular type of interstitial lung disease or pneumonia, is documented.
• Always review the entire medical record to confirm that the condition is indeed alveolar or parietoalveolar and not better described by another code.
