CPT® Code 82705

A laboratory test designated by CPT® Code 82705 is utilized to qualitatively assess the presence or absence of excess fat or lipids in feces. This test is crucial for understanding how the body processes dietary fats, which are typically broken down in the intestine through the action of pancreatic enzymes and bile. The breakdown process involves the conversion of neutral fats, such as monoglycerides, diglycerides, and triglycerides, into free fatty acids, a process referred to as splitting fats. When there is an elevation in neutral fats, it may indicate issues related to the synthesis or secretion of pancreatic enzymes and/or bile, which are essential for proper fat digestion. Conversely, an increase in split fats can suggest that the body is experiencing difficulties in nutrient absorption. Clinically, the presence of excess fat in feces can manifest through symptoms such as persistent diarrhea, abdominal pain, and steatorrhea, which is characterized by fatty stools. To conduct this test, a stool sample is collected, which can be a random sample or collected over a period of 24, 48, or 72 hours. It is imperative that the sample remains uncontaminated by urine, toilet water, or toilet paper to ensure accurate results. The qualitative analysis of the fecal sample is performed using microscopy or staining techniques to detect the fat content.
