Malignant neoplasm of medulla of unspecified adrenal gland

This code signifies a cancerous tumor originating in the inner part (medulla) of an adrenal gland, where the specific side (left or right) is not documented. These tumors often produce hormones like adrenaline and noradrenaline, leading to various systemic symptoms.

Apply this code when medical record documentation clearly indicates a primary malignant neoplasm of the adrenal medulla, but the laterality (left or right adrenal gland) is not specified. This is typically used for initial diagnoses or when laterality cannot be determined from available clinical information.

• Do not use this code if the documentation specifies the affected adrenal gland as left (C74.11) or right (C74.12).
• Ensure the pathology report or physician documentation confirms malignancy and adrenal medulla origin.
• Consider sequencing this code after any codes for associated endocrine disorders or symptoms caused by hormone overproduction.
