K58.8: Other and unspecified irritable bowel syndrome
Irritable Bowel Syndrome (IBS) coded as K58.8 refers to "Other and Unspecified IBS", terms used when the IBS is non-specific or does not fit neatly into the more common categories. IBS is a chronic digestive problem that primarily affects the large intestine. Typical symptoms include abdominal pain, cramping, bloating, gas, and changes in bowel habits such as diarrhea or constipation, or sometimes alternation between the two. These are often relieved by passing a bowel movement. It's important to know that IBS does not cause changes in bowel tissue or increase your risk of colorectal cancer. The exact cause of IBS isn't known, but several factors such as infections, inflammation, abnormalities in the nervous system, and changes in gut bacteria may play a role. Stress or changes in diet may also trigger symptoms.
