Malignant neoplasm of labia minora

This code signifies a primary cancerous growth originating in the labia minora, which are the inner folds of the vulva. This malignancy can be squamous cell carcinoma, adenocarcinoma, or other less common histological types affecting this specific anatomical site.

Assign this code when documentation confirms a primary malignant neoplasm exclusively located in the labia minora. This typically follows a biopsy and pathological confirmation of malignancy. Use for initial diagnosis, treatment, and follow-up care related to this specific cancer.

• Ensure documentation specifies "labia minora" to differentiate from other vulvar sites.
• Do not use for secondary or metastatic neoplasms to this site; a primary site code would be required.
• Consider an additional code for the specific histological type of neoplasm if documented and a more specific ICD-9-CM code exists.
