What This Code Means

Chronic inflammation with ulcers in the rectum and sigmoid colon that is causing bleeding from the rectum.

Coding Tips

  • Verify rectal bleeding is documented and attributed to the ulcerative rectosigmoiditis
  • This is a common complication; ensure bleeding is specifically noted in the record

Clinical Significance

Ulcerative rectosigmoiditis with rectal bleeding indicates active hemorrhagic complication of inflammation in the rectum and sigmoid colon. Bleeding from this anatomic distribution is a common manifestation of disease flare and may require treatment escalation, iron supplementation, or transfusion in severe cases.

Documentation Requirements

  • Confirmed ulcerative colitis involving rectum and sigmoid colon
  • Documentation of rectal bleeding including frequency and severity
  • Provider attribution of bleeding to the rectosigmoiditis
  • Laboratory values (hemoglobin, hematocrit) if clinically significant bleeding
  • Treatment plan addressing active disease and bleeding
  • Disease activity assessment
