Crohn's disease of small intestine with rectal bleeding

This code identifies Crohn's disease, a chronic inflammatory bowel disease, specifically affecting the small intestine. The "011" subclassification indicates the presence of rectal bleeding as a current symptom or complication of the small intestinal involvement.

Apply this code when documentation confirms a diagnosis of Crohn's disease localized to the small intestine, and the patient is experiencing or has recently experienced rectal bleeding attributable to this condition. Supporting documentation should clearly link the rectal bleeding to the Crohn's disease of the small bowel.

• Ensure the documentation explicitly states small intestinal involvement and rectal bleeding.
• Do not use if the Crohn's disease is localized to other areas of the gastrointestinal tract or if the rectal bleeding is from an unrelated cause.
• Consider additional codes for specific complications or manifestations of Crohn's disease if documented (e.g., strictures, fistulas).
