Small intestinal bacterial overgrowth
ICD-10 K63.821 is a used to indicate a diagnosis of small intestinal bacterial overgrowth.
Small intestinal bacterial overgrowth (SIBO) is a condition characterized by an abnormal increase in the overall bacterial population in the small intestine, particularly types of bacteria not commonly found in that part of the digestive tract. Clinically, patients may present with symptoms such as bloating, diarrhea, abdominal pain, and malabsorption, which can lead to weight loss and nutritional deficiencies. The anatomy involved primarily includes the small intestine, which is responsible for nutrient absorption. The disease progression can vary; if left untreated, SIBO can lead to chronic gastrointestinal issues and complications such as intestinal damage and further malabsorption. Diagnostic considerations for SIBO typically involve breath tests (such as lactulose or glucose breath tests) to measure hydrogen and methane levels, as well as stool tests to assess fat malabsorption. A thorough patient history and physical examination are also critical to rule out other gastrointestinal disorders that may mimic SIBO symptoms.

K63.821 specifically covers small intestinal bacterial overgrowth, which may be associated with conditions such as irritable bowel syndrome (IBS), celiac disease, and other disorders that affect gut motility or anatomy.
K63.821 should be used when there is a confirmed diagnosis of SIBO based on clinical evaluation and diagnostic testing, differentiating it from other gastrointestinal disorders that may present with similar symptoms.
Documentation for K63.821 should include a detailed patient history, results from breath tests or stool tests confirming SIBO, and any relevant treatment plans or referrals to specialists.
