Crohn's disease affecting both the small and large intestines without any complications like bleeding, obstruction, or infection.
Coding Tips
- •Confirm documentation specifies involvement of both small and large intestine (ileocolonic disease)
- •Use this code only when no complications are documented; add additional codes if complications are present
Clinical Significance
Crohn's disease of both small and large intestine without complications (ileocolonic Crohn's disease) is the most common presentation pattern of Crohn's disease, affecting approximately 40-50% of patients. This widespread involvement indicates a more extensive disease process that may require more aggressive treatment. Accurate site specification as ileocolonic is important for clinical decision-making and risk stratification.
Documentation Requirements
- ✓Provider documentation explicitly stating Crohn's disease involving BOTH small and large intestine
- ✓Diagnostic evidence of disease in both locations (imaging, endoscopy, pathology)
- ✓Confirmation that no current complications exist
- ✓Disease activity status and current treatment regimen
- ✓Surveillance plan appropriate for ileocolonic disease
