Personal history of malignant carcinoid tumor of thymus

This code indicates a patient's past medical history of a malignant carcinoid tumor that originated in the thymus gland. It signifies that the patient has been diagnosed with and treated for this specific type of neuroendocrine tumor in the past, and it is no longer an active disease process.

Apply this code when documenting a patient's history of a successfully treated malignant thymic carcinoid tumor. This is relevant for follow-up care, risk assessment for recurrence, and when the history impacts current treatment decisions for unrelated conditions. It should be used when the primary malignancy has been excised or eradicated and there is no evidence of current disease.

• Do not use this code if the patient has active thymic carcinoid cancer or metastatic disease; instead, code the active malignancy.
• Always sequence this code as a secondary diagnosis, as it represents a historical condition.
• Ensure documentation clearly states "history of" or "personal history of" and specifies the malignant nature and thymic origin of the carcinoid tumor.
