Crohn's disease of large intestine with rectal bleeding

This code identifies Crohn's disease specifically affecting the large intestine, characterized by chronic inflammation of the bowel wall. The "111" subclassification indicates the presence of active rectal bleeding as a current symptom or complication of the disease.

Apply this code when documentation confirms a diagnosis of Crohn's disease localized to the colon, and the patient is experiencing or has recently experienced rectal bleeding attributable to their Crohn's. Supporting documentation includes colonoscopy reports, physician notes detailing active bleeding, and pathology findings consistent with Crohn's colitis.

• Ensure documentation explicitly links the rectal bleeding to the Crohn's disease of the large intestine, rather than another source.
• Do not use this code if the Crohn's disease affects other parts of the gastrointestinal tract without specific involvement of the large intestine.
• Consider sequencing with codes for specific complications of Crohn's if present and documented (e.g., stricture, fistula), but the bleeding should be primary if it's the reason for the encounter.
