Personal history of in-situ neoplasm of cervix uteri

This code indicates a patient's past medical history of a non-invasive cancerous growth (carcinoma in situ) that was confined to the cervix and has since been treated or resolved. It signifies that while the patient previously had a pre-malignant lesion, there is no current evidence of active cervical cancer. This history is important for ongoing surveillance and risk assessment.

Use this code for patients who have a documented history of cervical carcinoma in situ (e.g., CIN III, HSIL) that has been successfully treated, such as by LEEP, conization, or ablation. It is appropriate when the patient is no longer undergoing active treatment for the in-situ lesion but requires continued monitoring due to this history. This code should be assigned as a secondary diagnosis to provide a comprehensive picture of the patient's health status.

• Do not use this code if the patient currently has an active in-situ neoplasm; instead, code the active condition.
• This is a history code, so it should generally be reported in conjunction with codes for current encounters, screenings, or follow-up care.
• Ensure documentation clearly specifies "in situ" and the cervical site to differentiate from invasive cancer or other gynecological conditions.
