High grade squamous intraepithelial lesion on cytologic smear of vagina (HGSIL)

BILLABLE STATUSYes

Code Description

ICD-10 R87.623 is a billable code used to indicate a diagnosis of high grade squamous intraepithelial lesion on cytologic smear of vagina (hgsil).

Key Diagnostic Point:

High grade squamous intraepithelial lesion (HGSIL) on a cytologic smear of the vagina indicates the presence of abnormal squamous cells that have a high likelihood of progressing to cervical cancer if left untreated. HGSIL is typically identified through Pap smear testing, which screens for precancerous changes in cervical cells. Symptoms may not be present, as many women with HGSIL are asymptomatic. However, some may experience abnormal vaginal bleeding, unusual discharge, or pelvic pain. The diagnosis is confirmed through further evaluation, including colposcopy and biopsy. Common causes of HGSIL include persistent infection with high-risk human papillomavirus (HPV) types, particularly HPV 16 and 18. Early detection and treatment are crucial to prevent progression to invasive cancer. The management of HGSIL often involves excisional procedures such as loop electrosurgical excision procedure (LEEP) or cone biopsy to remove the affected tissue.
