Mixed irritable bowel syndrome
ICD-10 K58.2 is a billable code used to indicate a diagnosis of mixed irritable bowel syndrome.
Mixed irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by a combination of symptoms including abdominal pain, bloating, and altered bowel habits, which may include both diarrhea and constipation. The condition affects the large intestine, or colon, and is thought to arise from a complex interplay of gut-brain axis dysfunction, visceral hypersensitivity, and altered gut motility. Patients often experience symptom fluctuations, making diagnosis challenging. The Rome IV criteria are commonly used for diagnosis, requiring the presence of abdominal discomfort or pain for at least one day per week in the last three months, associated with two or more of the following: related to defecation, a change in frequency of stool, or a change in form of stool. Diagnostic considerations may include ruling out other gastrointestinal disorders through laboratory tests, imaging studies, and endoscopic evaluations. The management of mixed IBS typically involves dietary modifications, pharmacotherapy, and psychological interventions, tailored to the individual's symptom profile.

K58.2 encompasses mixed irritable bowel syndrome, which includes symptoms of both diarrhea and constipation. It is important to differentiate it from other IBS subtypes, such as IBS with predominant diarrhea (K58.0) or constipation (K58.1).
K58.2 should be used when a patient presents with a combination of diarrhea and constipation symptoms, and when the clinical picture does not fit exclusively into one of the other IBS subtypes. Accurate symptom documentation is crucial for code selection.
Documentation should include a detailed symptom history, frequency and nature of bowel movements, any dietary factors, and previous treatments. Evidence of ruling out other gastrointestinal disorders is also essential.
