CPT® Code 82945

The CPT® Code 82945 refers to the testing of glucose levels in body fluids other than blood. This procedure involves the analysis of various types of body fluids, which may include pericardial fluid (the fluid surrounding the heart), peritoneal fluid (the fluid within the abdominal cavity), pleural fluid (the fluid between the layers of the pleura surrounding the lungs), and synovial fluid (the fluid found in joint cavities). The primary purpose of this test is to measure glucose concentration, which can provide valuable diagnostic information. A decreased glucose concentration in these fluids is often indicative of underlying septic or inflammatory processes. For instance, in cases of pleural effusion, low glucose levels may suggest conditions such as empyema (a collection of pus in the pleural cavity), tuberculosis, malignant neoplasms, or rheumatoid effusions. The collection of these body fluids is performed through specific procedures, which are separately reportable, including pericardiocentesis, thoracentesis, peritoneocentesis, or aspiration of synovial fluid. The analysis of the collected body fluid for glucose is typically conducted using enzymatic methodologies, ensuring accurate measurement and assessment of glucose levels in the sample.
