Irritable Bowel Syndrome with Diarrhea (IBS-D) is a functional gastrointestinal disorder characterized by chronic abdominal pain or discomfort and frequent bouts of diarrhea.
Causes
The exact cause of IBS-D is unknown, but it may involve a combination of factors such as intestinal motility issues, hypersensitivity to bowel distention, and psychological stress.

Stressful life events or mental health issues
Being younger than 50
Having a history of gastrointestinal infections
Symptoms
Frequent loose or watery stools
Abdominal pain or cramping, often relieved by bowel movements
An urgent need to move the bowels
Bloating or gas
Diagnosis
Diagnosis is often based on symptoms, medical history, and exclusion of other conditions.
Tests may include stool studies, blood tests, colonoscopy, or lactose intolerance tests to rule out other causes.
Treatment Options
Dietary changes, such as adopting a low-FODMAP diet
Medications: antidiarrheal agents, antispasmodic drugs, and certain antidepressants
Psychological therapy: cognitive-behavioral therapy (CBT) or stress management
Probiotics may help balance gut bacteria

Tips for Medical Coders
Ensure the specific diagnosis of IBS with diarrhea is documented, as different types of IBS have distinct codes.
Confirm accurate and up-to-date patient records; avoid general coding without specifying the IBS subtype as K58.0.
