0.000What This Code Means
A weakened, bulging section of an artery in the leg or foot that can potentially rupture and cause serious bleeding.
Coding Tips
- •Specify laterality (right/left) and anatomical location (femoral, popliteal, etc.) if documented
- •Distinguish between ruptured and non-ruptured presentations
Clinical Significance
Aneurysm of a lower extremity artery, most commonly the popliteal artery, is clinically significant due to the high risk of distal embolization and acute limb ischemia. Popliteal aneurysms are the most common peripheral arterial aneurysm and frequently present with thrombotic or embolic complications rather than rupture. Accurate coding captures this vascular disease burden requiring ongoing surveillance.
Documentation Requirements
- ✓Identification of specific lower extremity artery (femoral, popliteal, tibial)
- ✓Imaging confirmation with size measurement
- ✓Laterality (right, left, or bilateral)
- ✓Assessment of distal perfusion and runoff vessels
- ✓Presence or absence of mural thrombus
- ✓Treatment plan (surveillance, anticoagulation, surgical bypass, or endovascular repair)
Commonly Confused Codes
I72.1 — Aneurysm of artery of upper extremity: different extremityI72.3 — Aneurysm of iliac artery: iliac arteries are pelvic, not lower extremityI74.3 — Embolism and thrombosis of arteries of the lower extremities: thromboembolic event rather than aneurysm itselfI70.2xx — Atherosclerosis of native arteries of extremities: stenotic disease, not aneurysmal
