2025 ICD-10-CM code K58.8
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Diseases of the digestive system - Other irritable bowel syndrome Chapter 11: Diseases of the digestive system Feed
Other irritable bowel syndrome; encompasses IBS cases not specifically classified as diarrhea-predominant, constipation-predominant, or mixed.
No specific modifiers are typically associated with K58.8.
Medical necessity is established through proper documentation showing that the patient meets diagnostic criteria for IBS.Symptoms must be documented for sufficient duration and severity, and other potential organic causes must be ruled out.
The clinical responsibility involves a thorough history taking, physical examination focusing on abdominal findings, and possibly ordering investigations (e.g., stool tests, colonoscopy, etc.) to exclude other potential causes.Managing symptoms and patient education on dietary modifications, stress management, and medication options (if necessary) is crucial.
In simple words: This code is for irritable bowel syndrome (IBS) that doesn't clearly fall into the categories of IBS with diarrhea, IBS with constipation, or a mix of both.It's used when a person has IBS symptoms but the type isn't easily defined.
This ICD-10-CM code, K58.8, designates "Other irritable bowel syndrome."It's applied to instances of irritable bowel syndrome (IBS) that don't neatly fit the categories of IBS with diarrhea (K58.0), IBS with constipation (K58.1), or mixed IBS (K58.2).The diagnosis relies on clinical presentation, excluding other intestinal pathologies.Documentation should clearly detail symptoms (abdominal pain, altered bowel habits, bloating, etc.) and the rationale for not classifying the case under more specific IBS subtypes.
Example 1: A 35-year-old female presents with intermittent abdominal pain, bloating, and alternating episodes of diarrhea and constipation for the past 6 months.Colonoscopy is normal.K58.8 is coded because her symptoms don't consistently fit a specific IBS subtype., A 28-year-old male reports chronic abdominal discomfort with infrequent bowel movements and bloating.No clear pattern of diarrhea or constipation is observed.Further investigations rule out other intestinal issues.K58.8 is the most appropriate code., A 60-year-old patient experiences fluctuating abdominal pain, occasional diarrhea, and some constipation.The physician documents a history of IBS, but the symptoms don't consistently align with any of the specific IBS subtypes, warranting use of K58.8.
Detailed history of symptoms (abdominal pain, bowel habits, bloating), duration of symptoms, response to any treatment, results of any investigations (e.g., colonoscopy, stool studies), and exclusion of other gastrointestinal diagnoses.The rationale for choosing K58.8 over other K58 codes must be clearly documented.
** K58.8 is a residual category for IBS cases not specifically fitting other K58 codes.Accurate documentation is essential to justify this code selection.Always refer to the most current ICD-10-CM coding guidelines.
