ICD-10 Code C74.11 – Malignant neoplasm of medulla of right adrenal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C74.11 – Malignant neoplasm of medulla of right adrenal gland
What it is
This code identifies a malignant tumor arising in the medulla of the right adrenal gland. Use it when documentation specifies the right adrenal medulla as the primary site.
Clinical signs
Clinical features vary; refer to documentation. Adrenal medullary tumors may present with signs related to hormone excess or an adrenal mass, but the record must support the diagnosis.
When to use this code
Use C74.11 when the provider documents a malignant neoplasm of the right adrenal medulla, including confirmed primary cancer at that site. It is appropriate for inpatient, outpatient, and oncology coding when laterality and location are clearly stated. If the record only says “adrenal cancer” or is unclear, check documentation.
Do not use for
Do not use this code for benign adrenal tumors, unspecified adrenal malignancy, or tumors of the left adrenal gland. Check documentation if the primary site is not clearly the right medulla.
Coding tip
Verify both laterality and the medullary location before assigning C74.11.
