What This Code Means

Cancer that starts in the inner portion (medulla) of the right adrenal gland, which produces stress hormones like adrenaline.

Coding Tips

  • The fifth character '1' indicates right side; ensure laterality is explicitly documented to differentiate from left (C74.12) or unspecified (C74.10)
  • Pheochromocytoma is the most common malignancy of the adrenal medulla; verify diagnosis and staging information in clinical documentation

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
