Benign neoplasm of left adrenal gland

This code identifies a non-cancerous growth originating in the left adrenal gland. These benign neoplasms are typically discovered incidentally during imaging studies performed for other conditions, or during workup for hormone imbalances if the tumor is functional.

Apply this code when documentation explicitly states a benign neoplasm (e.g., adenoma, pheochromocytoma that is confirmed benign) located specifically in the left adrenal gland. This diagnosis is often supported by imaging reports (CT, MRI) and pathology results confirming benignity.

• Ensure laterality is clearly documented as "left" adrenal gland; do not use for unspecified or right-sided lesions.
• Distinguish from malignant neoplasms (C74.12) or neoplasms of uncertain behavior (D44.12) based on pathology.
• If the benign neoplasm is functional (e.g., secreting hormones), also code the associated endocrine disorder (e.g., E26.0 for primary hyperaldosteronism).
