What This Code Means

Growths in the colon caused by inflammation that are blocking the passage of stool through the intestines.

Coding Tips

•Confirm that the obstruction is directly related to the inflammatory polyps and not from other causes
•Consider whether the obstruction is partial or complete, as this may affect clinical management and documentation

Clinical Significance

Inflammatory polyps of the colon with intestinal obstruction is an uncommon but serious complication where large or numerous pseudopolyps cause bowel obstruction. This indicates severe prior inflammatory damage and may require surgical management, particularly if polyps are too numerous or large to be managed endoscopically.

Documentation Requirements

✓Colonoscopy or imaging documenting inflammatory polyps
✓Evidence of intestinal obstruction on imaging or clinical examination
✓Documentation of obstruction severity and relationship to the polyps
✓Provider statement linking obstruction to the inflammatory polyps
✓Treatment plan including possible surgical consultation
✓Assessment of underlying ulcerative colitis disease status

Commonly Confused Codes

K51.412 vs K56.69 — K56.69 is other intestinal obstruction unrelated to inflammatory bowel disease K51.412 vs K51.012 — K51.012 is pancolitis with obstruction; K51.412 specifically involves inflammatory polyps causing obstruction K51.412 vs D12.x with K56 — Adenomatous polyps causing obstruction would use neoplasm codes, not inflammatory bowel disease codes
