Personal history of malignant carcinoid tumor of rectum

This code indicates that a patient has a past medical history of a malignant carcinoid tumor that originated in the rectum. While the tumor is no longer present (e.g., due to successful treatment), its prior existence is clinically significant for ongoing surveillance and management.

Apply this code when documenting a patient's history of a resected or successfully treated malignant carcinoid tumor of the rectum. This is used for follow-up encounters, surveillance, or when the history impacts current treatment decisions for other conditions. It signifies that the patient is no longer actively being treated for the carcinoid tumor itself.

• Always sequence this code as a secondary diagnosis, as it represents a history, not a current active malignancy.
• Do not use this code if the patient is still undergoing active treatment for the rectal carcinoid tumor; in such cases, a code from the C7A.0 series would be more appropriate.
• Ensure documentation clearly states the tumor was malignant and located in the rectum, and that it is no longer present.
