CPT® Code 86152

The CPT® Code 86152 refers to a specialized laboratory test known as cell enumeration, which utilizes immunologic selection and identification techniques on fluid specimens, such as blood. This test is particularly significant in the context of oncology, as it is designed to detect circulating tumor cells (CTCs) in patients who have been diagnosed with cancer. The presence of these tumor cells in bodily fluids is indicative of metastatic disease, which is the process by which cancer spreads from its original site to other parts of the body through the circulatory system, including blood, bone marrow, and lymphatic pathways. Identifying circulating tumor cells can provide critical insights into the prognosis of the disease and inform treatment decisions for various types of cancer, including but not limited to breast, colorectal, prostate, renal, bladder, and non-small cell lung cancers. The detection of these cells is often associated with a poorer survival rate, making this test a valuable tool in the management of cancer patients. The procedure typically involves obtaining a blood sample through a separately reportable venipuncture, while other body fluids may be collected via different methods, such as a bone marrow biopsy for bone marrow samples or alternative techniques for lymphatic fluid. The blood sample may be analyzed using a cell search method, which yields a positive result if five or more circulating tumor cells are identified, or through morphological appearance, which necessitates microscopic examination to visualize the cells. Additionally, a physician's interpretation and report may be required to provide a comprehensive understanding of the test results. For billing purposes, the code 86152 is used for the cell enumeration test, while 86153 is designated for any necessary physician interpretation and reporting associated with the test.
