What This Code Means

Reduced blood flow affecting a large portion of the large intestine that is reversible and does not result in tissue death.

Coding Tips

•Diffuse colonic ischemia may involve multiple segments or the entire colon
•Document the anatomical extent and whether perfusion improves with intervention

Clinical Significance

Diffuse acute reversible ischemia of large intestine represents widespread colonic vascular compromise with high risk of progression to extensive bowel necrosis. This condition requires emergency intervention and intensive monitoring due to potential for life-threatening complications.

Documentation Requirements

✓Acute severe abdominal symptoms
✓Imaging showing diffuse large bowel ischemia
✓Documentation of extensive/diffuse involvement
✓Confirmation of reversible ischemic changes
✓Absence of established colonic infarction
✓Vascular pathology and risk factors identified
✓Emergency treatment and response documented

Commonly Confused Codes

K55.042 — Diffuse acute infarction when tissue death occurred K55.031 — Focal ischemia when involvement is segmental only K55.039 — Unspecified extent when diffuse pattern documented K51.90 — Ulcerative colitis without ischemic component
