CPT® Code 83690

The CPT® Code 83690 refers to the laboratory test for measuring lipase levels in blood and body fluids. Lipase is a crucial enzyme produced by the pancreas, which plays a significant role in the digestion of dietary fats by breaking them down into fatty acids and glycerol. This test is particularly important in diagnosing various medical conditions, as elevated lipase levels can indicate several health issues. Conditions such as small bowel obstruction, celiac disease, cholecystitis, duodenal ulcer, severe gastroenteritis, macrolipasemia, pancreatitis, and pancreatic tumors may lead to increased lipase levels in the body. Additionally, this test may be ordered in cases where there is a family history of lipoprotein lipase deficiency, which can affect lipid metabolism. The procedure involves obtaining a blood sample through venipuncture, which is separately reportable, while other body fluids may be collected using different methods. The analysis of these samples is conducted using quantitative enzymatic methodology, ensuring accurate measurement of lipase levels for diagnostic purposes.
