What This Code Means

A ruptured bulging of the aorta in the chest and upper abdomen area, specifically involving the area around the visceral arteries.

Coding Tips

•Paravisceral indicates involvement near the visceral arteries (celiac, superior mesenteric, renal) - confirm this location in operative or imaging reports
•Document any associated organ ischemia or complications from the rupture

Clinical Significance

Ruptured paravisceral aneurysm of the thoracoabdominal aorta involves the aortic segment at the level of the visceral arteries (celiac, superior mesenteric artery, renal arteries) and represents a surgical emergency. The paravisceral location creates extreme complexity for repair due to the need to maintain or reconstruct blood flow to multiple vital organs. This code captures both the severity of rupture and the anatomic complexity.

Documentation Requirements

✓Documentation of paravisceral location (at the level of visceral branch vessels)
✓Evidence of rupture through imaging, operative findings, or clinical deterioration
✓Status of visceral branch vessel involvement
✓Hemodynamic assessment and resuscitation documentation
✓Surgical approach and branch vessel management
✓Post-procedure organ function assessment (renal, hepatic, intestinal)

Commonly Confused Codes

I71.62 — Paravisceral aneurysm of the thoracoabdominal aorta, without rupture: intact aneurysm without evidence of rupture I71.51 — Supraceliac aneurysm of the thoracoabdominal aorta, ruptured: supraceliac is above the celiac trunk, a different anatomic zone I71.50 — Thoracoabdominal aortic aneurysm, ruptured, unspecified: use paravisceral when documentation supports the specific location I71.3 — Abdominal aortic aneurysm, ruptured: does not capture the thoracoabdominal extent
