Assessing the Positive Predictive Value of International Classification of Diseases Code K55.0 for Identifying Acute Mesenteric Ischaemia

Background

Acute mesenteric ischaemia (AMI) includes acute superior mesenteric artery (SMA) thrombosis and embolism, venous AMI, and non-occlusive mesenteric ischaemia (NOMI). Patients with AMI are identified using the International Classification of Diseases (tenth revision (ICD-10)) code K55.0 (acute vascular disorders of the intestine). Reporting of outcomes depends on reliable case identification.
