Neoplasm of uncertain behavior of right adrenal gland

This code signifies a tumor in the right adrenal gland that pathologists cannot definitively classify as benign or malignant based on microscopic examination. It indicates an intermediate stage where the biological behavior of the neoplasm is uncertain.

Apply this code when pathology reports describe a right adrenal mass with features that are neither clearly benign nor clearly malignant, often termed "uncertain malignant potential" or "indeterminate." Documentation must explicitly state the uncertainty of the tumor's behavior and its location in the right adrenal gland.

• Ensure the laterality (right adrenal gland) is clearly documented; do not use for left or bilateral adrenal involvement.
• Distinguish from benign adrenal adenomas (D35.01) or malignant adrenal carcinomas (C74.01).
• Always review the final pathology report for definitive classification; this code is typically temporary until a conclusive diagnosis is made.
