Malignant neoplasm of other specified sites of pleura

This code signifies a primary cancerous tumor originating in the pleura, specifically in a location other than those explicitly classified elsewhere (e.g., parietal, visceral, or unspecified pleura). It indicates a malignant growth within the membranes lining the lungs and thoracic cavity.

Apply this code when documentation clearly identifies a primary malignant neoplasm of the pleura, and the specific site is described as "other specified" or a less common pleural location not covered by more specific codes. Supporting documentation would include pathology reports confirming malignancy and imaging/surgical reports detailing the tumor's origin within the pleura.

• Ensure the neoplasm is primary to the pleura; metastatic disease to the pleura is coded differently.
• Distinguish from mesothelioma, which has its own specific codes (e.g., 163.0-163.1).
• Always review the pathology report for definitive diagnosis and specific site identification.
