0.000What This Code Means
Crohn's disease of the large intestine with an abnormal tunnel-like connection (fistula) between the intestine and other organs or skin.
Coding Tips
- •Document the location and type of fistula when possible (enterocutaneous, enterovesical, etc.) for complete coding
- •Fistulas are a common complication of Crohn's disease; ensure documentation clearly identifies this complication
Clinical Significance
Crohn's disease of the large intestine with fistula indicates penetrating disease behavior in the colon, creating abnormal connections to other structures. Colonic fistulas may be colovesical (to bladder), colovaginal, colocutaneous, or enteroenteric. This complication significantly impacts quality of life and often requires biologic therapy, surgical diversion, or complex resection.
Documentation Requirements
- ✓Provider documentation of Crohn's disease of the large intestine with fistula
- ✓Type and location of fistula (colovesical, colovaginal, colocutaneous, perianal, etc.)
- ✓Diagnostic method (imaging, endoscopy, examination under anesthesia)
- ✓Drainage status and treatment approach
- ✓Impact on functional status and quality of life
