ICD-10 Code D35.0 – Benign neoplasm of adrenal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D35.0 – Benign neoplasm of adrenal gland
What it is
D35.0 identifies a noncancerous tumor of the adrenal gland. Use it when documentation states a benign adrenal neoplasm, including incidental adrenal masses confirmed as benign.
Clinical signs
Clinical features vary; refer to documentation. Some benign adrenal tumors are asymptomatic and found on imaging, while others are evaluated for endocrine activity or mass effect.
When to use this code
Use D35.0 when the provider documents a benign adrenal gland tumor or benign adrenal mass. It is appropriate for confirmed benign lesions, including pathology or imaging-supported diagnoses. If the record only says adrenal nodule or incidentaloma without benign confirmation, check documentation.
Do not use for
Do not use this code for malignant adrenal neoplasms, adrenal hyperplasia, or unspecified adrenal masses without benign confirmation. Check documentation if the diagnosis is uncertain.
Coding tip
Code the adrenal laterality only if the record supports it and the payer requires additional specificity.
