Valid for Submission
| ICD-10: | C51.0 |
| Short Description: | Malignant neoplasm of labium majus |
| Long Description: | Malignant neoplasm of labium majus |
Code Classification
C51.0 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of labium majus. The code C51.0 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code C51.0 might also be used to specify conditions or terms like carcinoma of bartholin's gland, carcinoma of vulva, malignant neoplasm of greater vestibular gland, malignant neoplasm of labia majora, neoplasm of labia majora , primary malignant neoplasm of labia majora, etc.
The code C51.0 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 apply to this code given the correct histological behavior: Bartholin's gland ; labia (skin) majora ; labium (skin) majus ; skin NOS female genital organs (external) labium NEC majus ; skin NOS labia ; skin NOS labia majora ; vestibular gland, greater ; etc
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 the code C51.0:
Inclusion Terms
Inclusion TermsThese 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
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 the code C51.0 are found in the index:
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 Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Carcinoma of Bartholin's gland
- Carcinoma of vulva
- Malignant neoplasm of greater vestibular gland
- Malignant neoplasm of labia majora
- Neoplasm of labia majora
- Primary malignant neoplasm of labia majora
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code C51.0 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 736 | UTERINE AND ADNEXA PROCEDURES FOR OVARIAN OR ADNEXAL MALIGNANCY WITH MCC | 13 | 4.2582 |
| 737 | UTERINE AND ADNEXA PROCEDURES FOR OVARIAN OR ADNEXAL MALIGNANCY WITH CC | 13 | 2.0582 |
| 738 | UTERINE AND ADNEXA PROCEDURES FOR OVARIAN OR ADNEXAL MALIGNANCY WITHOUT CC/MCC | 13 | 1.4766 |
| 739 | UTERINE AND ADNEXA PROCEDURES FOR NON-OVARIAN AND NON-ADNEXAL MALIGNANCY WITH MCC | 13 | 3.8217 |
| 740 | UTERINE AND ADNEXA PROCEDURES FOR NON-OVARIAN AND NON-ADNEXAL MALIGNANCY WITH CC | 13 | 1.8 |
| 741 | UTERINE AND ADNEXA PROCEDURES FOR NON-OVARIAN AND NON-ADNEXAL MALIGNANCY WITHOUT CC/MCC | 13 | 1.2795 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Table of Neoplasms
The code C51.0 is included 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.

Information for Patients
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.
