Carcinoma in situ of other female genital organs

This code signifies the presence of non-invasive malignant cells confined to the epithelial layer of female genital organs other than the cervix, vagina, or vulva. This includes sites such as the fallopian tube, ovary, uterus (NOS), or other specified female genital organs. It represents a pre-invasive stage of cancer where the abnormal cells have not spread beyond their original location.

Apply this code when documentation confirms carcinoma in situ of a female genital organ not specifically covered by D06 (cervix), D07.2 (vagina), or D07.1 (vulva). This is typically supported by pathology reports indicating intraepithelial neoplasia or carcinoma in situ without evidence of stromal invasion. Common scenarios include incidental findings during hysterectomy or oophorectomy.

• Ensure the pathology report explicitly states "in situ" or "intraepithelial neoplasia" without invasion.
• Confirm the specific anatomical site to differentiate from D06, D07.1, or D07.2.
• Do not use this code if there is any evidence of invasion; instead, select the appropriate malignant neoplasm code for the specific site.
