Irritable bowel syndrome, unspecified

This code represents a functional gastrointestinal disorder characterized by chronic abdominal pain or discomfort, bloating, and altered bowel habits (diarrhea, constipation, or both) without an identifiable organic cause. It signifies a diagnosis of irritable bowel syndrome where the specific subtype (e.g., with diarrhea, with constipation) has not been documented.

Use this code when the provider's documentation clearly states a diagnosis of Irritable Bowel Syndrome (IBS) but does not specify the predominant bowel habit. This code is appropriate when the physician has diagnosed IBS but further clinical details regarding the subtype are absent or inconclusive.

• Avoid using this code if the documentation specifies IBS with diarrhea (IBS-D), IBS with constipation (IBS-C), or IBS with mixed bowel habits (IBS-M).
• Query the provider for clarification on the IBS subtype if possible, as more specific codes are available.
• This code should not be used for functional dyspepsia or other functional GI disorders that are not explicitly diagnosed as IBS.
