What This Code Means

A chronic inflammatory condition of the rectum (the lowest part of the colon) with ulcers and a collection of pus (abscess) that has formed.

Coding Tips

• •Verify documentation confirms both ulcerative proctitis and abscess presence before coding
• •Ensure this is documented as chronic ulcerative colitis affecting the rectum specifically

Clinical Significance

Ulcerative proctitis with abscess indicates a localized collection of pus complicating rectal inflammation. This serious infectious complication typically requires drainage and antibiotic therapy, increasing healthcare resource utilization. The presence of an abscess may also indicate more severe underlying disease activity.

Documentation Requirements

• ✓Confirmed ulcerative colitis limited to the rectum
• ✓Imaging or examination confirming abscess presence and location
• ✓Documentation of abscess size if available
• ✓Provider statement linking the abscess to the ulcerative proctitis
• ✓Treatment plan including antibiotics, incision and drainage, or surgical intervention
• ✓Follow-up plan for abscess resolution and disease management
