CPT® Code 81015

The CPT® Code 81015 refers to a specific type of urinalysis known as "microscopic only." This procedure involves the examination of urine sediment under a microscope to identify any abnormalities that may indicate medical conditions such as infections. The microscopic analysis is crucial for diagnosing various urinary tract issues, as it allows healthcare professionals to observe the presence of different cellular components and other substances in the urine. During the procedure, urine samples are typically processed using a centrifuge, which concentrates the sediment at the bottom of the tube. The remaining liquid is carefully decanted, leaving a small volume of liquid that contains the sediment. This sediment is then resuspended and placed in a test well designed for microscopic examination. The test well features a grid that aids in the systematic counting and identification of various elements, including crystals, casts, squamous cells, and other debris. The analysis is performed at both low and high power magnifications to accurately assess the presence and quantity of red blood cells (RBCs), white blood cells (WBCs), epithelial cells, bacteria, yeast, and crystals. The counting methodology varies based on the concentration of these constituents, ensuring that accurate results are obtained for clinical interpretation.
