In simple words: This code indicates that a person has Crohn's disease, an inflammatory bowel disease, in both their small and large intestines.

Crohn's disease (regional enteritis) involving both the small and large intestine.This code should be used when the disease affects both areas of the intestine.

Example 1: A patient presents with abdominal pain, diarrhea, and weight loss. After undergoing a colonoscopy and small bowel imaging, Crohn's disease is diagnosed in both the small and large intestines., A patient with a history of Crohn's disease in the small intestine now shows evidence of inflammation extending into the large intestine based on imaging results., A patient experiences an exacerbation of Crohn's disease with symptoms indicating involvement of both the small and large bowel confirmed by endoscopic and radiologic findings.

Documentation should include the location of the inflammation (small and large intestine), diagnostic methods used (e.g., colonoscopy, imaging), and clinical manifestations (e.g., abdominal pain, diarrhea, weight loss).Any associated complications, such as strictures or fistulas, should also be documented.

** For accurate coding, it is crucial to distinguish Crohn's disease affecting both the small and large intestines from conditions affecting only one or the other.Clear documentation of the diagnostic findings is essential.
