Irritable bowel syndrome with diarrhea
ICD-10 K58.0 is a billable code used to indicate a diagnosis of irritable bowel syndrome with diarrhea.
Irritable bowel syndrome with diarrhea (IBS-D) is a functional gastrointestinal disorder characterized by chronic abdominal pain and altered bowel habits, specifically diarrhea. The pathophysiology of IBS-D involves a complex interplay of gut-brain interactions, altered gut motility, visceral hypersensitivity, and changes in gut microbiota. Patients typically present with symptoms such as frequent loose stools, urgency, and abdominal discomfort that may improve after bowel movements. The anatomy involved includes the large intestine, where motility and secretion are disrupted. Disease progression can vary, with some patients experiencing intermittent symptoms while others may have more persistent issues. Diagnostic considerations for IBS-D include a thorough clinical history, symptom assessment, and exclusion of other gastrointestinal conditions such as inflammatory bowel disease (IBD) or infections. The Rome IV criteria are often utilized for diagnosis, requiring recurrent abdominal pain at least one day per week in the last three months, associated with changes in stool frequency or form. Laboratory tests and imaging are generally not required unless other conditions are suspected.

K58.0 specifically covers irritable bowel syndrome with diarrhea, characterized by recurrent abdominal pain and diarrhea. It excludes other forms of IBS that may present with constipation or mixed symptoms.
K58.0 should be used when the patient presents with predominant diarrhea as a symptom of IBS. It is important to differentiate it from K58.1, which is used for IBS with constipation.
Documentation should include a detailed patient history, symptom frequency and duration, and any diagnostic tests performed to rule out other conditions. The use of the Rome IV criteria for diagnosis should also be noted.
