Prsnl hx of malig neoplm of rectum, rectosig junct, and anus

This code indicates a patient's past medical history of a malignant tumor that originated in the rectum, rectosigmoid junction, or anus, and has since been successfully treated or is currently in remission. It signifies that the patient no longer has an active malignancy in these specific anatomical sites but has a documented history of such a diagnosis.

Apply this code when documenting follow-up care for patients who have completed treatment for a primary malignancy of the rectum, rectosigmoid junction, or anus. This includes surveillance visits, management of long-term side effects from treatment, or when the history impacts current treatment decisions for unrelated conditions.

• Always sequence this code as a secondary diagnosis, following the code for the reason for the encounter.
• Ensure the medical record clearly states the malignancy is no longer active or has been successfully excised/treated.
• Do not use this code if the patient has a current, active malignancy in the specified sites; instead, use the appropriate active malignancy code.
