ICD-10 Code I77.4 – Celiac artery compression syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I77.4 – Celiac artery compression syndrome
What it is
I77.4 identifies celiac artery compression syndrome, a condition where the celiac artery is compressed, usually by surrounding structures. It may also be called median arcuate ligament syndrome in clinical documentation.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include postprandial abdominal pain, weight loss, and sometimes nausea or vomiting, especially when imaging supports vascular compression.
When to use this code
Use this code when the provider documents celiac artery compression syndrome or median arcuate ligament syndrome. It is appropriate when the diagnosis is confirmed or clearly stated as the reason for evaluation, imaging, or treatment planning. Check documentation if symptoms are present but the syndrome is not established.
Do not use for
Do not use I77.4 for nonspecific abdominal pain, mesenteric ischemia, or other vascular disorders without documented celiac artery compression. If the record does not clearly identify this syndrome, code the documented condition instead.
Coding tip
Confirm the provider’s exact wording, because “celiac artery compression” and “median arcuate ligament syndrome” may both support I77.4 when documented.
