ICD-10 Code C74.92 – Malignant neoplasm of unspecified part of left adrenal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C74.92 – Malignant neoplasm of unspecified part of left adrenal gland
What it is
This code identifies a malignant tumor in the left adrenal gland when the exact adrenal subsite is not documented. Use it for primary adrenal cancer on the left side, not for metastasis or benign adrenal disease.
Clinical signs
Clinical features vary; refer to documentation. Patients may have adrenal mass findings on imaging, abdominal or flank pain, or signs of hormone excess if the tumor is functional.
When to use this code
Use C74.92 when the record clearly states malignant neoplasm of the left adrenal gland but does not specify the exact part of the gland. It also fits when pathology or imaging supports a primary left adrenal malignancy and no more specific code is available. Check documentation if laterality or primary site is unclear.
Do not use for
Do not use this code for benign adrenal tumors, adrenal incidentalomas, or secondary metastatic disease to the adrenal gland. If the chart names a different adrenal site or another primary cancer, code that condition instead.
Coding tip
Verify laterality and whether the tumor is primary or metastatic before assigning C74.92.
