Malignant neoplasm of cortex of right adrenal gland

This code signifies a primary cancerous tumor originating in the outer layer (cortex) of the right adrenal gland. This malignancy arises from the hormone-producing cells of the adrenal cortex, which can lead to various endocrine dysfunctions depending on the type of cells involved.

Apply this code when documentation clearly indicates a primary malignant neoplasm specifically located in the cortex of the right adrenal gland. This diagnosis is typically confirmed through imaging studies (e.g., CT, MRI) and biopsy, with pathology reports specifying the laterality and origin within the adrenal gland.

• Ensure documentation specifies "right" adrenal gland and "cortex" to differentiate from left or medulla involvement.
• Distinguish between primary malignant neoplasm and secondary (metastatic) malignancy to the adrenal gland.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, followed by any associated endocrine manifestations.
