ICD-10 Code K55.062 – Diffuse acute infarction of intestine, part unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K55.062 – Diffuse acute infarction of intestine, part unspecified
What it is
K55.062 identifies an acute loss of blood flow causing infarction across a diffuse area of the intestine, with the exact bowel segment not specified. Use it when the documentation confirms diffuse intestinal infarction but does not name the part involved.
Clinical signs
Clinical features may include sudden abdominal pain, tenderness, and signs of bowel ischemia or necrosis. Clinical features vary; refer to documentation for imaging, operative, or pathology confirmation.
When to use this code
Use this code when the provider documents diffuse acute intestinal infarction and does not identify a specific segment such as small bowel or colon. It also fits when the record supports acute infarction of the intestine overall, but the anatomic site remains unspecified.
Do not use for
Do not use it for chronic intestinal ischemia, noninfarction ischemic bowel conditions, or infarction limited to a clearly documented intestinal part. Check documentation if the record names a more specific bowel segment.
Coding tip
Assign the most specific intestinal site available; if the part is not stated, K55.062 is appropriate.
