2025 ICD-10-CM code C51
(Active) Effective Date: N/A Neoplasms - Malignant neoplasms of female genital organs 2: Neoplasms Feed
Malignant neoplasm of vulva.
Medical necessity is established by the presence of a histologically confirmed malignant neoplasm of the vulva.
Diagnosis and treatment are typically managed by gynecologic oncologists and may involve biopsy, imaging (CT, MRI, PET), surgical resection (partial or total vulvectomy, lymph node dissection), radiation therapy, and/or chemotherapy.
In simple words: Vulvar cancer is a rare type of cancer affecting the external female genitalia (vulva). It involves abnormal cell growth that can potentially spread to surrounding tissues and other body parts.
Malignant neoplasm of the vulva, encompassing all subcategories and histological types, including squamous cell carcinoma, melanoma, adenocarcinoma, sarcoma, and Paget's disease of the vulva. This code excludes carcinoma in situ of the vulva (D07.1).
Example 1: A 65-year-old female presents with a persistent vulvar lesion, confirmed as squamous cell carcinoma via biopsy. C51 is used to code the diagnosis., A 45-year-old female with a history of HPV infection is diagnosed with vulvar melanoma. C51 is used to code the diagnosis., A 70-year-old female undergoes a radical vulvectomy for advanced vulvar cancer involving the clitoris and labia minora. C51 is applicable for pre-operative diagnosis coding.
Documentation should include location and size of the tumor, histological type, diagnostic methods used (biopsy, imaging), clinical findings, and treatment plan.
** Excludes carcinoma in situ of vulva (D07.1)
