Malignant neoplasm of vagina

This code signifies the presence of a primary cancerous tumor originating in the vaginal tissues. It represents invasive malignancy, meaning the cancer has spread beyond the superficial layer of cells. This diagnosis indicates a serious condition requiring definitive treatment.

Assign this code when documentation confirms an invasive malignant neoplasm of the vagina. This typically follows biopsy confirmation of malignancy. Use this code for primary vaginal cancer, not for metastatic disease to the vagina from another primary site.

• Differentiate carefully between primary vaginal malignancy and metastatic disease to the vagina; the latter would be coded to the secondary site.
• Ensure the pathology report confirms invasive carcinoma, not carcinoma in situ, to avoid miscoding with D07.2.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter or treatment.
