ICD-10 Code C74.01 – Malignant neoplasm of cortex of right adrenal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C74.01 – Malignant neoplasm of cortex of right adrenal gland
What it is
This code identifies a malignant tumor arising from the cortex of the right adrenal gland. Use it when documentation specifies primary cancer of the right adrenal cortex.
Clinical signs
Clinical features vary; refer to documentation. Adrenal cortical malignancies may be found because of an abdominal mass, pain, or hormone-related findings, but the chart should clearly support the diagnosis.
When to use this code
Use C74.01 when the provider documents malignant neoplasm of the cortex of the right adrenal gland, including pathology-confirmed disease or a clearly stated clinical diagnosis. Code it for the right-sided primary site when laterality is specified. If the record only says adrenal cancer without cortical or side detail, check documentation.
Do not use for
Do not use this code for benign adrenal tumors, adrenal medullary tumors, or metastatic disease to the adrenal gland. If the site is unspecified or the laterality is not documented, check documentation.
Coding tip
Confirm both the adrenal cortex site and right laterality before assigning C74.01.
