About the D06 Code Range
The ICD-10 code D06 and its subcodes are specifically used to classify carcinoma in situ of the cervix uteri, a condition where abnormal cells are found on the surface of the cervix but have not yet invaded deeper tissues. These codes distinguish between different parts of the cervix affected and the certainty of diagnosis.
This section includes codes such as D06.0 for carcinoma in situ of the endocervix, also known as adenocarcinoma in situ of the cervix or endocervical adenocarcinoma in situ; D06.1 for carcinoma in situ of the exocervix, sometimes called neoplasm of exocervix; and D06.7 for carcinoma in situ of other parts of the cervix. When exact location is not specified, D06.9 is used, which covers conditions described as cervical intraepithelial neoplasia, squamous cell carcinoma in situ of the uterine cervix, or high-grade cervical glandular intraepithelial neoplasia. These codes provide a precise way for healthcare providers and coders to report pre-invasive cervical cancer conditions, facilitating accurate documentation and treatment planning.
