Prsnl history of malig neoplm of resp and intrathorac organs

This code indicates that a patient has a past medical history of a primary malignant tumor affecting respiratory or intrathoracic organs other than those specifically classified elsewhere (e.g., lung, bronchus, larynx). This means the patient has completed active treatment for the malignancy and is now considered in remission or cured, but the history of the cancer remains relevant for ongoing care.

Use this code when documenting a patient's history of a successfully treated malignant neoplasm of sites such as the trachea, mediastinum, pleura, thymus, or heart. It is appropriate for follow-up visits, surveillance, or when the history impacts current treatment decisions for unrelated conditions. Do not use this code if the patient is currently undergoing active treatment for the malignancy or if there is evidence of recurrence or metastasis.

• Always sequence this code after any current, active conditions for which the patient is being seen.
• Ensure the specific primary site of the past malignancy is not better represented by a more specific Z85.2x code (e.g., Z85.21 for lung cancer).
• Do not use this code if the patient has a current malignancy, even if it's a different primary site; instead, code the active malignancy.
