The cost of coronary angiography and stenting are set by the price bureau, and the reimbursement rate is also specified by the local health insurance department. The cost of coronary angiography alone is about RMB 5,000. Stent cost: Stents are divided into imported drug-coated stents, domestic drug-coated stents and drug balloons. The cost of imported stents is generally up to 20,000 yuan (before reimbursement), and the cost of domestic stents is half of it, about 10,000 yuan. The drug balloon is a bit more expensive, costing nearly 30,000 yuan (before reimbursement). In terms of Beijing health insurance, whether it is an imported stent, a domestic stent or a drug balloon, it is 70% reimbursed and 30% out of pocket. In addition, the cost of the pressure transducer (a device to monitor intravascular pressure) used during surgery, in addition to the stent, is about 340 RMB, which is completely self-paying. The total cost of the guidewire and pre-dilated balloon used during the operation is about 10,000 yuan, which is also 30% out of pocket. If intravascular ultrasound (IVUS) or coronary flow reserve (FFR) is required during the procedure, it is currently completely self-paying, costing 20,000 yuan and 10,000 yuan respectively. The cost of coronary angiography and its related interventions is still quite large, which is a significant expense for the average family and should be budgeted for. Of course, the need for coronary angiography depends on the condition and medical advice.
