Mild vaginal dysplasia

This code represents a low-grade squamous intraepithelial lesion (LSIL) of the vagina, indicating mild cellular changes that are not cancerous but may progress if left untreated. It signifies the earliest stage of abnormal cell growth on the vaginal surface, often detected during a Pap test or colposcopy.

Use this code when documentation explicitly states "mild vaginal dysplasia," "vaginal LSIL," or "CIN 1 of the vagina." This diagnosis is typically confirmed by biopsy results following an abnormal Pap smear. Ensure the physician's notes clearly indicate the location as vaginal, not cervical.

• Differentiate carefully between vaginal dysplasia and cervical dysplasia (CIN), as these have distinct codes.
• Ensure the documentation specifies "mild" or "low-grade" to support this specific code.
• If the dysplasia is moderate or severe, a different code from the N89 series would be appropriate.
