CPT® Code 88175

Cytopathology, cervical or vaginal (any reporting system), collected in preservative fluid, automated thin layer preparation; with screening by automated system and manual rescreening or review, under physician supervision

Cytopathology examination, specifically for cervical or vaginal specimens, is a critical diagnostic procedure aimed at identifying cellular changes that may indicate the presence of disease. This examination is particularly important for detecting conditions such as cervical dysplasia and in situ carcinoma, which are precursors to invasive malignant diseases. The procedure is commonly known as a Papanicolaou (PAP) smear, where cells are collected from the endocervix using specialized tools like a brush or stick. These collected specimens are then placed in a preservative fluid to maintain cell integrity during transport to the laboratory. Once at the laboratory, the specimen undergoes a process where the liquid cell suspension is centrifuged to eliminate debris, allowing for a concentrated retrieval of cervical cells. The preparation of these cells involves an automated system that stains the cells and transfers them onto slides, which are then covered with slips for protection. The automated system plays a crucial role in screening and interpreting the prepared smears, enhancing the efficiency and accuracy of the examination. In the context of CPT® Code 88175, the automated screening results are further evaluated by a trained technician who performs manual rescreening of the PAP smear under the supervision of a physician, typically a pathologist. This manual rescreening entails a thorough reassessment of the entire slide to ensure that any abnormal findings are accurately identified. If abnormalities are detected, the pathologist may suggest follow-up actions, such as scheduling another PAP smear sooner than the standard interval or conducting additional diagnostic tests like colposcopy, endocervical curettage, or biopsy to further investigate the findings.
