ICD-10 Code D44.11 – Neoplasm of uncertain behavior of right adrenal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D44.11 – Neoplasm of uncertain behavior of right adrenal gland
What it is
D44.11 identifies a right adrenal gland mass or neoplasm whose behavior is not clearly benign or malignant. Use it when the record documents uncertain behavior, not a confirmed cancer diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Patients may have an adrenal incidentaloma, imaging findings of an adrenal mass, or signs that prompt evaluation for adrenal hormone activity.
When to use this code
Use D44.11 when the provider documents a neoplasm of uncertain behavior in the right adrenal gland. This code fits cases where pathology or imaging has not established benign or malignant behavior. If the note only says “adrenal mass” or “lesion,” check documentation before coding.
Do not use for
Do not use this code for clearly benign adrenal adenoma or for confirmed malignant adrenal tumors. If the record specifies a different adrenal side or an unspecified adrenal gland, select the matching code instead.
Coding tip
Verify laterality and the exact wording of the provider’s assessment before assigning D44.11.
