0.000What This Code Means
A bulging or weakening of the aorta in the chest and upper abdomen area, specifically involving the area around the visceral arteries, that has not ruptured.
Coding Tips
- •Paravisceral location indicates proximity to celiac, superior mesenteric, or renal arteries - verify exact location in imaging reports
- •Document any involvement of visceral vessels and baseline renal function for monitoring purposes
Clinical Significance
Paravisceral aneurysm of the thoracoabdominal aorta without rupture involves the aortic segment at the level of the major visceral arteries. This location creates unique surgical challenges as any intervention must preserve blood flow to the celiac trunk, superior mesenteric artery, and renal arteries. The anatomic specificity of this code supports recognition of the complexity of the patient's vascular disease.
Documentation Requirements
- ✓Documentation of paravisceral location (at the level of visceral branch arteries)
- ✓Imaging confirmation with diameter measurements
- ✓Statement that the aneurysm is intact without rupture
- ✓Assessment of branch vessel involvement or compression
- ✓Surveillance plan and imaging intervals
- ✓Surgical risk stratification and candidacy assessment
