Coding Tips
Clinical Significance
Malignant neoplasm of the medulla of the right adrenal gland represents malignant pheochromocytoma or neuroblastoma on the right side. The right adrenal gland's proximity to the inferior vena cava creates surgical complexity. Malignant pheochromocytoma requires preoperative alpha-blockade and careful hemodynamic management.
Documentation Requirements
- ✓Pathology confirming malignancy with evidence of metastatic disease (defining feature of malignant pheochromocytoma)
- ✓Documentation confirming right-sided medullary involvement
- ✓Catecholamine and metanephrine laboratory values
- ✓Blood pressure management documentation
- ✓Staging and metastatic workup results
Commonly Confused Codes
C74.12 — Left adrenal medulla: Laterality error; confirm right sideC74.01 — Right adrenal cortex: Different compartment — verify medulla vs. cortexC74.91 — Right adrenal, unspecified part: Use C74.11 when medulla is specifically documentedD35.01 — Benign neoplasm of right adrenal gland: Benign pheochromocytoma is much more common
