The cost of surgery for intracranial aneurysms is relatively high, with open clamping procedures costing about $50,000-$70,000 to treat. Minimally invasive procedures for interventional embolization cost $100,000-$200,000, with some procedures costing even more. The cost of treatment is related to the size of the aneurysm, with larger aneurysm interventions costing even $300,000-500,000. Medicare can reimburse some of the costs, and interventional procedures are reimbursed at 50%-70%. Many imported materials are reimbursed at a lower rate by Medicare. Reimbursement for open-heart surgery is higher and can reach about 80%.
