Cancer that starts in the outer layer (cortex) of the left adrenal gland, a small hormone-producing gland that sits on top of the kidney.
Coding Tips
Clinical Significance
Malignant neoplasm of the cortex of the left adrenal gland is the left-sided counterpart of adrenocortical carcinoma. Left adrenal tumors may involve the left renal vein and splenic vasculature, creating distinct surgical considerations. Accurate laterality and compartment coding supports appropriate treatment planning and resource allocation.
Documentation Requirements
- ✓Pathology confirming adrenocortical carcinoma of the left adrenal gland
- ✓Documentation confirming left-sided involvement
- ✓Hormonal evaluation and functional status
- ✓Staging information
- ✓Confirmation of cortex (not medulla) as tissue of origin
Commonly Confused Codes
C74.01 — Right adrenal cortex: Laterality reversal; confirm left sideC74.12 — Left adrenal medulla: Different compartment — cortex produces steroids, medulla produces catecholaminesC74.92 — Left adrenal, unspecified part: Use C74.02 when cortex is specifiedD35.02 — Benign neoplasm of left adrenal gland: Confirm malignancy before codingC79.72 — Secondary malignant neoplasm of left adrenal gland: Metastatic, not primary
