Supraceliac aneurysm of the thoracoabdominal aorta, ruptured

This code signifies a life-threatening condition involving a ruptured aneurysm located in the supraceliac segment of the thoracoabdominal aorta. This specific anatomical location refers to the portion of the aorta above the celiac artery origin, extending into the thoracic and abdominal regions. Rupture indicates a tear in the aortic wall, leading to hemorrhage and requiring immediate surgical intervention.

Apply this code when documentation clearly states a ruptured aneurysm of the thoracoabdominal aorta, specifically identifying its supraceliac location. This diagnosis is typically made based on imaging studies (e.g., CT angiography) confirming the aneurysm and evidence of rupture (e.g., retroperitoneal hemorrhage, hemothorax). It is crucial for cases presenting with acute onset of severe pain, hypotension, and signs of internal bleeding.

• Ensure the documentation explicitly specifies "ruptured" and the "supraceliac" location; otherwise, an unruptured or unspecified code may be more appropriate.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, given its acute and critical nature.
• Differentiate from other aortic aneurysm codes by carefully reviewing the anatomical site (e.g., infrarenal, thoracic, abdominal only) and the presence or absence of rupture.
