What This Code Means
R87.623 is the ICD-10-CM diagnosis code for high grade squamous intraepithelial lesion on cytologic smear of vagina (hgsil). A vaginal Pap smear showing high-grade precancerous changes in squamous cells (HGSIL), indicating significant abnormalities with substantial risk of progression to cancer if untreated. R87.623 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering abnormal findings on examination of other body fluids, substances and tissues, without diagnosis (r83-r89).
R87.623 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
HGSIL findings require colposcopy with biopsy for confirmation and treatment planning.
