Secondary malignant neoplasm of pleura

This code signifies the presence of a malignant tumor in the pleura that originated from a primary cancer elsewhere in the body. It indicates metastatic disease affecting the lining of the lungs and chest cavity.

Use this code when documentation confirms a secondary or metastatic malignancy involving the pleura, often identified through imaging (e.g., CT scan, PET scan) or biopsy. This typically occurs in patients with a known history of a primary cancer that has spread.

• Always code the primary malignant neoplasm first, followed by this code for the secondary site.
• Distinguish from primary pleural malignancies (e.g., mesothelioma), which have different code assignments.
• Ensure documentation clearly states "secondary," "metastatic," or "spread to" the pleura.
