Secondary malignant neoplasm of left adrenal gland

This code signifies the presence of a malignant tumor in the left adrenal gland that originated from a primary cancer site elsewhere in the body. It indicates that the adrenal gland is a site of metastatic disease, not the primary source of the malignancy.

Apply this code when documentation explicitly states metastatic cancer to the left adrenal gland. This is commonly seen in patients with a history of primary lung, breast, kidney, or melanoma cancers that have spread. Supporting documentation includes pathology reports confirming malignancy and imaging studies (e.g., CT, MRI) identifying the lesion in the left adrenal gland.

• Always sequence the primary malignancy code before this secondary site code.
• Do not use this code for primary adrenal gland malignancies; those are found in the C74 category.
• Ensure laterality is clearly documented (left vs. right adrenal gland) to select the correct specific code.
