In simple words: The Pap smear or other cell test from your vagina showed some abnormal cells, but the changes don't fit into the usual categories like ASC-US, LSIL, or HSIL.  More investigation may be needed to determine the significance of these findings.

This code signifies the presence of abnormal cellular changes detected during a cytological examination of a vaginal specimen that do not fall into other specific categories such as atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), or cytologic evidence of malignancy. It is used when the cytological findings are abnormal but do not fit neatly into other defined categories.

Example 1: A 35-year-old female undergoes a routine Pap smear. The cytology report indicates abnormal cell changes consistent with reactive cellular changes, but not dysplasia or malignancy. The appropriate code is R87.628., A 50-year-old female with a history of vaginal atrophy presents for a gynecological exam. Her Pap smear reveals abnormal cytological findings, possibly related to atrophy, but not suggestive of precancerous or cancerous changes. The code R87.628 is used., A 25-year-old female presents with vaginal discharge. A wet mount reveals the presence of an unusual infection. While the infection is identified, there are also abnormal cytological findings noted that are not directly attributable to the infection. In addition to the code for the infection, R87.628 is assigned to document the other abnormal cytological changes.

The medical record should include detailed documentation of the cytological findings from the vaginal specimen, including descriptions of cell morphology and any associated clinical findings. The report from the laboratory performing the cytology analysis is essential.
