ICD-11 DA94.01 — Chronic non-specific multiple ulcers of small intestine

In CNSU patients chronic non-specific multiple ulcers are predominantly found in the ileum, which are circular or irregular in shape. The margins of ulcers are always clear and the intervening mucosa appears normal. CNSU is often characterised by anaemia and hypoalbuminemia due to bleeding and protein loss from multiple ulcers.
