C51.0 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of labium majus. 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 Bartholin's gland ; Neoplasm, neoplastic labia (skin) majora ; Neoplasm, neoplastic labium (skin) majus ; Neoplasm, neoplastic skin NOS female genital organs (external) labium NEC majus ; Neoplasm, neoplastic skin NOS labia ; Neoplasm, neoplastic skin NOS labia majora ; Neoplasm, neoplastic vestibular gland, greater ; etc
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Basal cell carcinoma of vulva
- Carcinoma of Bartholin's gland
- Carcinoma of vulva
- Carcinoma of vulva
- Malignant neoplasm of greater vestibular gland
- Malignant neoplasm of labia majora
- Neoplasm of labia majora
- Primary basal cell carcinoma of skin of labium majus
- Primary malignant neoplasm of labia majora
- Primary malignant neoplasm of left greater vestibular gland
- Primary malignant neoplasm of right greater vestibular gland
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Malignant neoplasm of Bartholin's greater vestibular gland
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:
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:

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.
»female genital organs (external)
»vestibular gland, greater
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.
