Malignant neoplasm of medulla of right adrenal gland

This code identifies a cancerous tumor originating in the inner part (medulla) of the adrenal gland located on the right side of the body. These neoplasms are typically pheochromocytomas, which arise from chromaffin cells and can produce excessive catecholamines.

Apply this code when documentation confirms a primary malignant neoplasm specifically located in the medulla of the right adrenal gland. This diagnosis is often supported by imaging studies (CT, MRI), biopsy results, and elevated catecholamine levels.

• Ensure laterality (right) is clearly documented; do not use for left or unspecified adrenal gland involvement.
• Confirm the neoplasm is primary malignant, not secondary (metastatic) or benign.
• Consider additional codes for any associated syndromes (e.g., MEN2) or symptoms related to catecholamine excess.
