Secondary malignant neoplasm of right adrenal gland

This code signifies the presence of a cancerous tumor in the right adrenal gland that originated from a primary cancer site elsewhere in the body. It indicates that the adrenal gland is not the initial location of the malignancy but rather a site of metastatic spread.

Apply this code when documentation clearly states a secondary or metastatic malignancy affecting the right adrenal gland. This is typically supported by pathology reports confirming metastatic disease, imaging studies showing adrenal involvement in a patient with a known primary cancer, or physician's notes explicitly diagnosing secondary right adrenal cancer.

• Always code the primary malignancy first, followed by this secondary site code.
• Distinguish carefully between primary adrenal gland malignancies (C74.-) and secondary ones.
• Ensure the laterality (right) is explicitly documented; if unspecified, use the unspecified adrenal gland code.
