Small intestinal bacterial overgrowth, hydrogen sulfide-subtype
ICD-10 K63.8212 is a billable code used to indicate a diagnosis of small intestinal bacterial overgrowth, hydrogen sulfide-subtype.
Small intestinal bacterial overgrowth (SIBO) is a condition characterized by an abnormal increase in the number of bacteria in the small intestine, particularly those that are typically found in the colon. The hydrogen sulfide subtype of SIBO is associated with specific gastrointestinal symptoms such as bloating, diarrhea, abdominal pain, and flatulence, which may be exacerbated by certain foods. The small intestine is anatomically divided into three sections: the duodenum, jejunum, and ileum. In SIBO, the normal digestive process is disrupted, leading to malabsorption of nutrients and fermentation of carbohydrates, resulting in the production of gases like hydrogen sulfide. Disease progression can lead to more severe complications such as nutrient deficiencies, weight loss, and even intestinal damage if left untreated. Diagnosis often involves breath tests measuring hydrogen and methane levels after carbohydrate ingestion, as well as clinical evaluation of symptoms. It is crucial for healthcare providers to consider SIBO in patients with unexplained gastrointestinal symptoms, particularly those who have undergone gastrointestinal surgery or have conditions that affect gut motility.

K63.8212 specifically covers small intestinal bacterial overgrowth with a focus on the hydrogen sulfide subtype, which is characterized by symptoms such as bloating, diarrhea, and abdominal discomfort. It is important to differentiate this from other types of SIBO and gastrointestinal disorders.
K63.8212 should be used when the clinical presentation and diagnostic testing confirm the presence of hydrogen sulfide-producing bacteria in the small intestine, distinguishing it from other subtypes or gastrointestinal conditions that may present similarly.
Documentation must include a detailed clinical history, symptom assessment, results from breath tests indicating hydrogen sulfide production, and any relevant imaging or laboratory findings that support the diagnosis of SIBO.
