What This Code Means

Chronic inflammation with ulcers in the rectum and sigmoid colon with a collection of pus (abscess) that has formed.

Coding Tips

  • Confirm abscess is documented and related to the ulcerative rectosigmoiditis
  • Note the location of the abscess if specified in the medical record

Clinical Significance

Ulcerative rectosigmoiditis with abscess indicates a localized pus collection complicating inflammation of the rectum and sigmoid colon. This infectious complication increases disease severity, requires targeted antibiotic therapy and likely drainage, and is associated with higher healthcare resource utilization and potential for systemic illness.

Documentation Requirements

  • Confirmed ulcerative colitis of the rectum and sigmoid colon
  • Imaging evidence of abscess with location and size documented
  • Provider statement linking abscess to the rectosigmoiditis
  • Treatment plan including antibiotics and drainage if indicated
  • Culture and sensitivity results if drainage was performed
  • Follow-up plan for abscess resolution monitoring
