Cancer of the left adrenal gland where the specific part of the gland (inner or outer layer) is not specified.
Coding Tips
Clinical Significance
Malignant neoplasm of unspecified part of the left adrenal gland provides laterality but lacks compartment detail. As with the right-sided counterpart, this code is appropriate when documentation confirms left adrenal cancer but does not specify whether the tumor arises from cortex or medulla.
Documentation Requirements
- ✓Documentation confirming left-sided adrenal malignancy
- ✓Pathology report — attempt to determine cortex vs. medulla origin
- ✓Hormonal evaluation to help identify tissue of origin
- ✓Staging information and extent of disease
- ✓Treatment status and follow-up plan
Commonly Confused Codes
C74.02 — Left adrenal cortex: Use when cortex origin is confirmedC74.12 — Left adrenal medulla: Use when medulla origin is confirmedC74.91 — Right adrenal, unspecified part: Laterality error; verify left sideC74.90 — Unspecified side and part: Use C74.92 when left side is documentedC79.72 — Secondary malignant neoplasm of left adrenal gland: Metastatic, not primary
