What This Code Means

Reduced blood flow to a specific segment of the small intestine that is reversible and does not result in tissue death.

Coding Tips

•Distinguish between focal (segmental) and diffuse involvement; focal affects a limited area while diffuse affects larger portions
•Confirm reversibility is documented; if tissue death occurs, use K55.02x codes instead

Clinical Significance

Focal acute reversible ischemia of small intestine indicates significant vascular compromise requiring immediate intervention and ongoing monitoring. This condition represents high-risk vascular disease with potential for progression to infarction and serious complications if untreated.

Documentation Requirements

✓Acute onset abdominal pain documented
✓Imaging confirmation of segmental small bowel ischemia
✓Documentation of focal/segmental involvement
✓Reversible nature of ischemia confirmed
✓Absence of bowel necrosis or infarction
✓Underlying vascular disease etiology identified
✓Treatment response and monitoring plan

Commonly Confused Codes

K55.021 — Focal acute infarction when tissue necrosis has occurred K55.012 — Diffuse acute ischemia when multiple segments involved K55.1 — Chronic vascular disorders for long-term ischemic changes K92.2 — Gastrointestinal hemorrhage without ischemic component
