ICD-10 Code C79.72 – Secondary malignant neoplasm of left adrenal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C79.72 – Secondary malignant neoplasm of left adrenal gland
What it is
This code identifies metastatic cancer in the left adrenal gland. Use it when a malignancy from another primary site has spread to that adrenal gland.
Clinical signs
Clinical features vary; refer to documentation. Imaging may show a left adrenal mass, and pathology or clinician notes should support that the lesion represents secondary malignant disease.
When to use this code
Use C79.72 when the record clearly documents metastasis to the left adrenal gland from a known primary cancer. It is appropriate for confirmed secondary involvement on imaging, biopsy, or specialist assessment. Code the primary malignancy separately when documented.
Do not use for
Do not use this code for a benign adrenal mass, a primary adrenal cancer, or unspecified adrenal laterality. If the chart does not confirm metastatic disease, check documentation.
Coding tip
Verify laterality and the metastatic nature of the lesion before assigning this code.
