ICD-10 Code K55.069 – Acute infarction of intestine, part and extent unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K55.069 – Acute infarction of intestine, part and extent unspecified
What it is
K55.069 identifies an acute loss of blood supply causing infarction of the intestine, when the affected bowel segment and extent are not specified. Use it for documented acute intestinal ischemia with tissue death, but no further anatomic detail.
Clinical signs
Clinical features vary; refer to documentation. Common references describe sudden abdominal pain, possible tenderness, and signs of acute bowel ischemia or necrosis, but the record must support infarction rather than simple ischemia.
When to use this code
Use this code when the provider documents acute infarction of the intestine and does not name the small bowel, large bowel, or another specific site. It also fits when the extent is not described, even if imaging or surgery confirms infarction. Check documentation for acuity and anatomic detail.
Do not use for
Do not use it for chronic intestinal ischemia, nonspecific abdominal pain, or bowel obstruction without infarction. If the chart identifies a specific intestinal segment or different vascular diagnosis, code that documented condition instead.
Coding tip
Look for wording such as “acute infarction,” “bowel infarction,” or operative confirmation, and code the most specific intestinal site available.
