Secondary malignant neoplasm of adrenal gland

This code indicates the presence of cancerous cells in the adrenal gland that originated from a primary tumor elsewhere in the body. It signifies metastatic disease affecting one or both adrenal glands, rather than a tumor that began in the adrenal gland itself.

Apply this code when documentation clearly states a secondary or metastatic malignancy involving the adrenal gland. This is typically used when a patient with a known primary cancer (e.g., lung, breast, kidney) develops new lesions in the adrenal gland confirmed to be metastases. Supporting documentation includes pathology reports, imaging studies (CT, MRI, PET scans) describing metastatic lesions, and physician notes.

• Always sequence the primary malignant neoplasm code before this secondary site code.
• Do not use this code for primary adrenal gland malignancies; refer to codes in the 193 series.
• Ensure the documentation explicitly states "secondary," "metastatic," or "spread to" the adrenal gland.
