Official Description

Starch granules, feces

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 89225 refers to the examination of a stool sample specifically for the presence of starch granules. This procedure involves collecting a sample of feces from a patient, which is then analyzed in a laboratory setting. Starch granules are microscopic structures that can be identified in the stool and may indicate certain dietary habits or digestive processes. The presence of these granules can provide valuable information regarding the patient's carbohydrate intake and the efficiency of their digestive system. This examination is particularly relevant in assessing malabsorption conditions or dietary compliance, as it helps healthcare professionals understand how well the body is processing starches. The analysis of starch granules in feces is a specialized test that requires careful collection and handling of the stool sample to ensure accurate results.

1. Indications

The examination for starch granules in feces is indicated in various clinical scenarios where understanding carbohydrate digestion and absorption is essential. The following conditions may warrant this procedure:

  • Malabsorption Syndromes - Patients exhibiting symptoms of malabsorption, such as chronic diarrhea, weight loss, or nutritional deficiencies, may require this test to evaluate their ability to digest starches.
  • Dietary Assessment - This procedure can be useful in assessing a patient's adherence to dietary recommendations, particularly in individuals on carbohydrate-restricted diets.
  • Gastrointestinal Disorders - Conditions affecting the gastrointestinal tract, such as celiac disease or pancreatic insufficiency, may necessitate the examination of stool for starch granules to determine the extent of digestive impairment.

2. Procedure

The procedure for examining stool samples for starch granules involves several key steps to ensure accurate results. First, a stool sample is collected from the patient, which should be done using a clean, dry container to avoid contamination. It is important that the sample is fresh and properly labeled with the patient's information to maintain traceability. Once the sample is obtained, it is transported to the laboratory for analysis. In the lab, the stool is processed, and a microscopic examination is performed to identify the presence of starch granules. This may involve preparing a slide with the stool sample and using specific staining techniques to enhance visibility of the granules under a microscope. The laboratory technician will then document the findings, noting the quantity and characteristics of any starch granules observed, which will be reported back to the healthcare provider for further evaluation.

3. Post-Procedure

After the stool sample has been analyzed for starch granules, the results will be compiled and communicated to the healthcare provider. Depending on the findings, further diagnostic testing or dietary modifications may be recommended. Patients may not require any specific post-procedure care, but they should be informed about the importance of following up with their healthcare provider to discuss the results and any necessary next steps. If the test indicates malabsorption or other gastrointestinal issues, additional evaluations or treatments may be initiated to address the underlying conditions.
