Legal analysis: 1. According to the 2020 medical insurance reimbursement policy, cerebral infarction is included in the medical insurance for chronic disease management of urban and rural residents, and the payment ratio is unified to 60. Stent implantation for cerebral infarction is also covered by medical insurance in most provinces. However, the materials and models of stents are very different, including imported stents and domestic stents. Some provinces reimburse based on whether the stents are registered, and the reimbursement ratios for domestically produced and imported stents are different, so the situation in each province is different. 2. If interventional treatment is required after evaluation, and if circumstances permit, you can check with the medical insurance before implanting a stent to see whether the stent to be implanted is within the scope of reimbursement and the specific reimbursement ratio. 3. Taking a hospital in Beijing as an example, patients who receive interventional treatment for acute cerebral infarction in this hospital can be reimbursed by medical insurance. Taking the intracranial stent surgery for acute cerebral infarction performed by this hospital as an example, the total cost is an average of 90,000 yuan. After the implementation of medical insurance reimbursement, insured patients only need to spend 20,000 to 30,000 yuan. Legal basis: "Social Insurance Law of the People's Republic of China" Article 30 The following medical expenses are not included in the payment scope of the basic medical insurance fund: (1) Should be paid from the work-related injury insurance fund; (2) Should be paid by a third party (3) Should be borne by the public health department; (4) Seek medical treatment abroad. Medical expenses shall be borne by a third party in accordance with the law. If the third party fails to pay or the third party cannot be identified, the basic medical insurance fund shall pay first. After the basic medical insurance fund has paid in advance, it has the right to recover compensation from the third party.
