0.000What This Code Means
A weakened, bulging section of the iliac artery in the lower abdomen or pelvis that can potentially rupture.
Coding Tips
- •Specify laterality (right/left) when documented
- •Confirm whether the aneurysm is ruptured, as this changes the code assignment
Clinical Significance
Iliac artery aneurysm is an important vascular condition that frequently coexists with abdominal aortic aneurysm and may be a site of significant morbidity if thrombosis or rupture occurs. Isolated iliac aneurysms are less common but can be clinically significant, particularly common iliac aneurysms. This code captures peripheral aneurysmal disease affecting the pelvic vasculature.
Documentation Requirements
- ✓Documentation specifying iliac artery aneurysm (common, internal, or external iliac)
- ✓Imaging confirmation with diameter measurement
- ✓Laterality (right, left, or bilateral)
- ✓Assessment of coexisting aortic aneurysm
- ✓Statement of intact vs ruptured status
- ✓Treatment plan (surveillance, endovascular, or surgical repair)
Commonly Confused Codes
I71.4 — Abdominal aortic aneurysm, without rupture: aortic not iliac — though they often coexist, code both when documentedI72.4 — Aneurysm of artery of lower extremity: iliac arteries are pelvic, not lower extremityI72.8 — Aneurysm of other specified arteries: iliac has its own specific codeI72.9 — Aneurysm of unspecified site: do not use when iliac is documented
