ICD-10 Code D35.01 – Benign neoplasm of right adrenal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D35.01 – Benign neoplasm of right adrenal gland
What it is
D35.01 identifies a noncancerous tumor of the right adrenal gland. It indicates a benign adrenal mass on the right side, not a malignant adrenal cancer.
Clinical signs
Clinical features vary; refer to documentation. Some patients have no symptoms and the mass is found incidentally, while others may have hormone-related findings if the lesion is functional.
When to use this code
Use D35.01 when the provider documents a benign neoplasm specifically in the right adrenal gland. Apply it for imaging or pathology-confirmed benign adrenal masses when laterality is clear. Check documentation if the lesion is described only as adrenal, adrenal mass, or incidentaloma.
Do not use for
Do not use this code for malignant adrenal tumors, adrenal hyperplasia, or unspecified adrenal masses. If the record does not confirm benign behavior or right-sided laterality, check documentation.
Coding tip
Confirm both benign behavior and right adrenal laterality before assigning D35.01.
