C51.1 - Malignant neoplasm of labium minus
| ICD-10: | C51.1 |
| Short Description: | Malignant neoplasm of labium minus |
| Long Description: | Malignant neoplasm of labium minus |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
C51.1 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of labium minus. 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 labia (skin) minora or Neoplasm, neoplastic labium (skin) minus or Neoplasm, neoplastic skin NOS female genital organs (external) labium NEC minus or Neoplasm, neoplastic skin NOS labia minora .
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Malignant neoplasm of labia minora
- Neoplasm of labia minora
- Primary malignant neoplasm of labia minora
Index to Diseases and Injuries References
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for this diagnosis code are found in the injuries and diseases index:

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
Vulvar Cancer
Vulvar cancer is a rare type of cancer. It forms in a woman's external genitals, called the vulva. The cancer usually grows slowly over several years. First, precancerous cells grow on vulvar skin. This is called vulvar intraepithelial neoplasia (VIN), or dysplasia. Not all VIN cases turn into cancer, but it is best to treat it early.
Often, vulvar cancer doesn't cause symptoms at first. However, see your doctor for testing if you notice:
- A lump in the vulva
- Vulvar itching or tenderness
- Bleeding that is not your period
- Changes in the vulvar skin, such as color changes or growths that look like a wart or ulcer
You are at greater risk if you've had a human papillomavirus (HPV) infection or have a history of genital warts. Your health care provider diagnoses vulvar cancer with a physical exam and a biopsy. Treatment varies, depending on your overall health and how advanced the cancer is. It might include surgery, radiation therapy, chemotherapy, or biologic therapy. Biologic therapy boosts your body's own ability to fight cancer.
