CPT® Code 88291

The CPT® Code 88291 refers to the process of cytogenetics and molecular cytogenetics, specifically focusing on the interpretation and reporting of laboratory tests. This procedure involves a detailed analysis of chromosomes, including their numbers and configurations, which are essential for understanding various genetic conditions. Cytogenetics examines the structure and function of chromosomes, while molecular cytogenetics delves deeper into the molecular aspects, providing insights into genetic abnormalities at a more granular level. The interpretation and report generated from these tests are crucial for diagnosing a range of conditions, including congenital anomalies, developmental delays, and infertility issues. Additionally, these tests are significant for females experiencing gonadal dysgenesis, for evaluating products of conception following spontaneous abortion, and for couples with a history of recurrent miscarriages. Furthermore, cytogenetic and molecular cytogenetic analyses play a vital role in the diagnosis and classification of hematologic and oncologic diseases, aiding in the determination of appropriate treatment plans and monitoring the patient's disease status and recovery. It is essential that each cytogenetic laboratory test is thoroughly analyzed and interpreted by at least two qualified professionals, ensuring that the evaluation is based on established criteria, which include the rationale for the study, the clinical reason for the referral, the type of tissue examined, the minimum number of cells counted or sorted, and the total number of cells analyzed and karyotyped.
