What This Code Means

Growths in the colon caused by inflammation that have developed a localized collection of pus (abscess).

Coding Tips

• •Verify that an abscess is specifically documented; this is a serious complication that may require drainage or surgical intervention
• •Document the location of the abscess if specified, as this provides important clinical context

Clinical Significance

Inflammatory polyps of the colon with abscess indicates both pseudopolyp formation and a localized purulent infection complicating the inflammatory bowel disease. This combination suggests severe disease requiring both medical and potentially surgical management, including antibiotics, drainage, and close monitoring for systemic infection.

Documentation Requirements

• ✓Colonoscopy documenting inflammatory polyps
• ✓Imaging or clinical evidence of abscess with location and size
• ✓Provider statement linking the abscess to the underlying colitis
• ✓Biopsy confirming inflammatory nature of polyps
• ✓Treatment plan including antibiotics and drainage if indicated
• ✓Follow-up plan for both polyps and abscess
