Other abnormal cytological findings on specimens from vagina

This code signifies the presence of atypical or abnormal cellular changes identified in a vaginal cytology specimen that do not fit more specific diagnostic categories. These findings are often indicative of cellular abnormalities that warrant further investigation but are not yet classified as dysplasia, malignancy, or specific infections.

Apply this code when a pathology report for a vaginal smear or biopsy indicates abnormal cytological findings that are not otherwise specified (NOS). This is appropriate for results such as "atypical squamous cells of undetermined significance (ASC-US)" or "atypical glandular cells (AGC)" when the specific site (e.g., cervix) cannot be definitively determined or when the findings are explicitly from the vagina. Documentation should clearly state the abnormal nature of the vaginal cytological findings.

• Do not use this code if the abnormal findings are definitively identified as originating from the cervix; use the appropriate R87.61x code instead.
• This code is often a temporary diagnosis, prompting further diagnostic workup. Code the definitive diagnosis once established.
• Ensure the pathology report explicitly states "vaginal" cytology and describes the findings as "other abnormal" or "unspecified abnormal" to support this code.
