Carcinoma in situ of vagina

📋Clinical Description

This code represents a non-invasive malignant epithelial lesion of the vagina, meaning the abnormal cells are confined to the surface layer and have not spread to deeper tissues. It is considered a pre-invasive form of squamous cell carcinoma of the vagina.

🎯When to Use

Assign this code when documentation specifies "carcinoma in situ of vagina" or "intraepithelial carcinoma of vagina." This diagnosis is typically made following a biopsy or excisional procedure.

💡Coding Tips

Do not use this code for vaginal intraepithelial neoplasia (VIN) grades I, II, or III, as these have specific codes.
Distinguish carefully between carcinoma in situ and invasive carcinoma; the latter requires a different code.
Ensure the pathology report explicitly states "carcinoma in situ" to support this diagnosis.
