ICD-10 Code D35.02 – Benign neoplasm of left adrenal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D35.02 – Benign neoplasm of left adrenal gland
What it is
This code identifies a noncancerous tumor in the left adrenal gland. It means the lesion is benign and specifically located on the left side.
Clinical signs
Many benign adrenal tumors are found incidentally on imaging and may cause no symptoms. Clinical features vary; refer to documentation for mass effect or any hormone-related findings.
When to use this code
Use D35.02 when the provider documents a benign neoplasm of the left adrenal gland. You may also use it when imaging or pathology confirms a benign left adrenal adrenal mass and the record does not describe malignancy.
Code this diagnosis for follow-up, evaluation, or surveillance of a documented benign left adrenal lesion. Check documentation if the chart only says “adrenal mass,” “adrenal nodule,” or “adrenal incidentaloma.”
Do not use for
Do not use this code for malignant adrenal tumors, adrenal hyperplasia, or unspecified adrenal masses. Check documentation if the laterality is not clearly left.
Coding tip
Verify both benign behavior and left-sided location before assigning D35.02.
