Malignant neoplasm of other endocrine glands and related structures

This code signifies a primary cancerous tumor originating in endocrine glands other than the thyroid, adrenal, parathyroid, thymus, or pancreas. It encompasses malignancies affecting less common endocrine structures or those not specified elsewhere.

Apply this code when documentation clearly indicates a primary malignant neoplasm of an endocrine gland or related structure not classified to a more specific ICD-9-CM code. Examples include tumors of the pineal gland or carotid body.

• Ensure the neoplasm is explicitly stated as primary and malignant.
• Always review documentation for a more specific endocrine gland site before using this code.
• Do not use for secondary (metastatic) neoplasms; use appropriate secondary malignancy codes.
