Summary
This policy establishes coverage criteria for endovascular stent grafts for abdominal aortic aneurysms (AAAs), defining specific medical necessity criteria including aneurysm diameter thresholds and anatomical requirements. The policy covers FDA-approved devices for AAAs meeting size criteria but considers treatment investigational for smaller aneurysms or high-risk patients ineligible for open repair.
Action Required
Immediately: Review current AAA cases to ensure they meet medical necessity criteria (aneurysm >5.0 cm diameter, 4-5.0 cm with 0.5 cm growth in 6 months, diameter twice normal infrarenal aorta size, or ruptured AAA). Document anatomical appropriateness and CT imaging for all endovascular stent graft procedures. Claims for smaller aneurysms or high-risk patients may be denied as investigational.
