| ICD-10: | D06.9 |

Table of Contents
D06.9 is a billable ICD-10 code used to specify a medical diagnosis of carcinoma in situ of cervix, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
This code is applicable to female patients only. It is clinically and virtually impossible to use this code on a non-female patient.
The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic cervix (cervical) (uteri) (uterus) or Neoplasm, neoplastic uterus, uteri, uterine cervix .
Unspecified diagnosis codes like D06.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Adenocarcinoma in situ of cervix
- Carcinoma in situ of uterine cervix
- Carcinoma in situ of uterus
- Carcinoma of cervix stage 0
- Cervical intraepithelial neoplasia
- Cervical intraepithelial neoplasia grade III with severe dysplasia
- Dysplasia of cervix
- Dysplasia of cervix
- High grade cervical glandular intraepithelial neoplasia
- Squamous cell carcinoma in situ of uterine cervix
- Tis: Carcinoma in situ
Clinical Information
- Cervical Intraepithelial Neoplasia-. a malignancy arising in uterine cervical epithelium and confined thereto, representing a continuum of histological changes ranging from well-differentiated cin 1 (formerly, mild dysplasia) to severe dysplasia/carcinoma in situ, cin 3. the lesion arises at the squamocolumnar cell junction at the transformation zone of the endocervical canal, with a variable tendency to develop invasive epidermoid carcinoma, a tendency that is enhanced by concomitant human papillomaviral infection. (segen, dictionary of modern medicine, 1992)
- High Grade Cervical Glandular Intraepithelial Neoplasia-. cervical glandular intraepithelial neoplasia characterized by the presence of severe dysplastic changes.

Code Edits
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:
- Diagnoses for females only - The Medicare Code Editor detects inconsistencies between a patient’s sex and any diagnosis on the patient’s record, these edits apply to FEMALES only .

| Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code. | ||
Table of Neoplasms
This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.
Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Patient Education
Cervical Cancer
The cervix is the lower part of the uterus, the place where a baby grows during pregnancy. Cervical cancer is caused by a virus called HPV. The virus spreads through sexual contact. Most women's bodies are able to fight HPV infection. But sometimes the virus leads to cancer. You're at higher risk if you smoke, have had many children, use birth control pills for a long time, or have HIV infection.
Cervical cancer may not cause any symptoms at first. Later, you may have pelvic pain or bleeding from the vagina. It usually takes several years for normal cells in the cervix to turn into cancer cells. Your health care provider can find abnormal cells by doing a Pap test to examine cells from the cervix. You may also have an HPV test. If your results are abnormal, you may need a biopsy or other tests. By getting regular screenings, you can find and treat any problems before they turn into cancer.
Treatment may include surgery, radiation therapy, chemotherapy, or a combination. The choice of treatment depends on the size of the tumor, whether the cancer has spread and whether you would like to become pregnant someday.
Vaccines can protect against several types of HPV, including some that can cause cancer.
