0.000What This Code Means
Crohn's disease of the small intestine with an abnormal tunnel-like connection (fistula) between intestinal segments or to other organs.
Coding Tips
- •Fistulas are a common complication of Crohn's disease requiring specific documentation
- •Document the location and type of fistula if available for additional specificity
Clinical Significance
Crohn's disease of the small intestine with fistula represents penetrating disease behavior, where chronic transmural inflammation creates abnormal connections between bowel segments or to other organs. Fistulas are a hallmark complication of Crohn's disease, often requiring biologic therapy and potentially complex surgical intervention. This complication significantly increases disease burden and treatment complexity.
Documentation Requirements
- ✓Provider documentation of Crohn's disease of the small intestine with fistula
- ✓Type and location of fistula (enteroenteric, enterocutaneous, enterovesical, enterovaginal, etc.)
- ✓Diagnostic confirmation method (imaging, surgical exploration, or clinical examination)
- ✓Current drainage status and treatment approach (biologics, seton placement, surgical repair)
- ✓Impact on nutritional status and quality of life
