Small intestinal bacterial overgrowth, hydrogen-subtype
ICD-10 K63.8211 is a billable code used to indicate a diagnosis of small intestinal bacterial overgrowth, hydrogen-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-subtype of SIBO is specifically associated with the production of hydrogen gas as a byproduct of bacterial fermentation. Clinically, patients may present with symptoms such as bloating, abdominal pain, diarrhea, and malabsorption, which can lead to nutritional deficiencies. The small intestine anatomy is crucial in understanding SIBO, as it is normally a relatively sterile environment, and the presence of excessive bacteria can disrupt normal digestive processes. Disease progression can vary, with some patients experiencing recurrent episodes, while others may develop chronic symptoms. Diagnostic considerations include breath tests that measure hydrogen and methane levels after carbohydrate ingestion, as well as small bowel aspirate and culture, although the latter is more invasive. Accurate diagnosis is essential for effective management and treatment, which may involve dietary modifications, antibiotics, and probiotics.

K63.8211 specifically covers small intestinal bacterial overgrowth with a hydrogen subtype, which is characterized by increased hydrogen production due to bacterial fermentation in the small intestine. It is important to differentiate this from other types of SIBO, such as methane-dominant SIBO, which may have different clinical implications.
K63.8211 should be used when there is a confirmed diagnosis of small intestinal bacterial overgrowth with hydrogen production, as evidenced by breath testing or other diagnostic criteria. It is essential to use this code when the clinical presentation aligns with the specific characteristics of hydrogen-subtype SIBO.
Documentation for K63.8211 should include a detailed clinical history, results from breath tests indicating hydrogen production, and any relevant imaging or laboratory studies that support the diagnosis of SIBO. Additionally, treatment plans and patient responses to therapy should be documented.
