Personal history of cervical dysplasia

This code indicates a patient's past medical history of abnormal cell growth on the surface of the cervix, which is not currently present. This condition, also known as cervical intraepithelial neoplasia (CIN), is a precursor to cervical cancer. The patient has been treated for this condition, and it is no longer active.

This code is used when a patient presents for follow-up care, screening, or treatment for other conditions, and their medical history includes a documented diagnosis and treatment of cervical dysplasia. It is appropriate for ongoing surveillance after successful treatment of CIN. Do not use this code if the dysplasia is currently active or if the patient has a history of invasive cervical cancer.

• Always confirm that the cervical dysplasia is no longer active and has been treated.
• Do not use this code if the patient has a current diagnosis of cervical dysplasia; instead, use codes from category N87.
• This code is often used in conjunction with screening codes (e.g., Z12.4) for routine gynecological exams in patients with a relevant history.
