Official Description

Fat or lipids, feces; quantitative

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 82710 refers to a laboratory test that quantitatively measures the levels of fat or lipids present in feces. This test is essential for evaluating how the body processes dietary fats, which are broken down in the intestine through the action of pancreatic enzymes and bile. The breakdown process involves converting neutral fats, which include monoglycerides, diglycerides, and triglycerides, into free fatty acids, commonly referred to as split fats. An increase in the levels of neutral fats in the feces may indicate issues related to the synthesis or secretion of pancreatic enzymes and bile, suggesting potential pancreatic dysfunction. Conversely, elevated levels of split fats can signify impaired nutrient absorption, which may lead to various gastrointestinal symptoms. Patients may experience persistent diarrhea, abdominal pain, and steatorrhea, characterized by the presence of fatty stools. To conduct this test, a stool sample is collected over a specified duration—either 24, 48, or 72 hours. It is crucial that the sample remains uncontaminated by urine, toilet water, or toilet paper to ensure accurate results. The analysis of the fecal sample is performed using nuclear magnetic resonance spectroscopy, a sophisticated technique that allows for precise measurement of fat content. Additionally, CPT® Code 82715 is related to this procedure, as it quantifies the differential fat composition within the sample, including components such as cholesterol, phospholipids, and triglycerides.

1. Indications

The quantitative measurement of fat or lipids in feces, as indicated by CPT® Code 82710, is performed for several specific clinical reasons. These indications include:

  • Persistent Diarrhea This symptom may suggest malabsorption issues, prompting the need to evaluate fat levels in feces.
  • Abdominal Pain Patients experiencing unexplained abdominal discomfort may undergo this test to determine if fat malabsorption is a contributing factor.
  • Steatorrhea The presence of fatty stools is a direct indication for this test, as it helps to assess the extent of fat malabsorption.

2. Procedure

The procedure for obtaining a quantitative measurement of fat or lipids in feces involves several critical steps to ensure accurate results. The first step is the collection of a stool sample over a designated period, which can be 24, 48, or 72 hours. During this time, the patient must adhere to specific dietary guidelines as instructed by their healthcare provider to avoid any interference with the test results. It is essential that the stool sample is collected in a clean container and that it remains uncontaminated by urine, toilet water, or toilet paper, as such contamination can lead to inaccurate measurements. Once the sample is collected, it is sent to a laboratory where it undergoes analysis. The laboratory utilizes nuclear magnetic resonance spectroscopy, a sophisticated technique that allows for the precise quantification of fat content in the feces. This method provides detailed insights into the types and amounts of fats present, which can aid in diagnosing potential malabsorption syndromes or pancreatic insufficiency.

  • Sample Collection A stool sample is collected over a specified duration (24, 48, or 72 hours) while ensuring it is free from contamination.
  • Laboratory Analysis The collected sample is sent to a laboratory where it is analyzed using nuclear magnetic resonance spectroscopy to quantify fat content.

3. Post-Procedure

After the procedure, the patient may not require any specific post-procedure care, as the stool sample collection is a non-invasive process. However, it is important for the patient to follow up with their healthcare provider to discuss the results of the test. The healthcare provider will interpret the findings in the context of the patient's symptoms and medical history. If elevated levels of fat are detected, further diagnostic evaluations or treatments may be recommended based on the underlying cause of the fat malabsorption. Patients should also be advised to maintain a record of any ongoing symptoms, as this information can be valuable for subsequent medical assessments.

90 Reference (outside) laboratory: when laboratory procedures are performed by a party other than the treating or reporting physician or other qualified health care professional, the procedure may be identified by adding modifier 90 to the usual procedure number.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
