CPT® Code 88143

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

Cytopathology examination, specifically for cervical or vaginal specimens, is a diagnostic procedure aimed at identifying cellular changes that may indicate the presence of disease. This examination is crucial for detecting conditions such as cervical dysplasia and in situ carcinoma, which are precursors to invasive malignancies. The procedure is commonly known as a Papanicolaou (PAP) smear, named after Dr. George Papanicolaou, who developed this method of screening. During the test, cells are collected from the endocervix using specialized tools, such as a brush or stick, and placed in a preservative fluid to maintain their integrity for laboratory analysis. Once the specimen reaches the laboratory, it undergoes a process where the liquid cell suspension is centrifuged to eliminate debris, allowing for a concentrated sample of cervical cells. These cells are then prepared using an automated thin layer preparation system, which stains the cells and transfers them onto slides for microscopic examination. The examination process involves manual screening by a trained technician under the supervision of a physician, specifically a pathologist. In the case of CPT® Code 88143, the procedure includes not only the initial manual screening but also a rescreening process, which entails a thorough reassessment of the entire slide, potentially by a second technician. This comprehensive approach ensures that any abnormal findings are accurately identified and communicated to the treating physician, who may then recommend further diagnostic tests or follow-up procedures based on the results.
