Personal history of malignant neoplasm of endocrine glands

This code indicates a patient's past diagnosis of a malignant tumor affecting an endocrine gland other than those specifically coded elsewhere (e.g., thyroid, adrenal). It signifies that the patient has completed active treatment for this cancer and is now in a state of remission or surveillance. This history is crucial for ongoing patient management and risk assessment.

Apply this code when documenting a patient's medical history for a resolved malignant neoplasm of an endocrine gland such as the parathyroid, pituitary, or thymus. It is used for follow-up visits, annual physicals, or when the history impacts current treatment decisions for unrelated conditions. Do not use for active malignancy or for primary sites with more specific history codes.

• Always sequence this code after any current, active malignancy codes if applicable, or as a primary diagnosis if no active cancer is present.
• Ensure the specific endocrine gland involved is not covered by a more precise Z85.8- subcategory (e.g., Z85.83 for thyroid).
• Verify that the neoplasm is indeed malignant and not benign or of uncertain behavior.
