Other alveolar and parieto-alveolar conditions

This code represents various non-specific conditions affecting the alveoli (air sacs) of the lungs and the surrounding parieto-alveolar structures, excluding those explicitly classified elsewhere. It encompasses a range of diffuse interstitial lung diseases or other alveolar abnormalities that do not fit more specific diagnostic categories.

Use this code when documentation indicates a diagnosis of an alveolar or parieto-alveolar condition that is not otherwise specified or classified under more precise ICD-10-CM codes. This often applies to preliminary diagnoses or when a definitive diagnosis for a specific interstitial lung disease (e.g., idiopathic pulmonary fibrosis, sarcoidosis) has not yet been established.

• Always seek more specific documentation if available, as this is a "catch-all" code.
• Differentiate from codes for specific interstitial lung diseases (e.g., J84.1- series) or other pulmonary conditions.
• Ensure the medical record clearly supports an alveolar or parieto-alveolar involvement when assigning this code.
