Type of disease: interventional treatment or surgery for simple congenital heart disease; radical surgery for complex congenital heart disease. 3.Funding amount: 10-20,000 RMB, generally no more than 40% of the overall hospitalization cost;. Ling Yan, Department of Pediatric Cardiology, Beijing Anzhen Hospital The rest of the hospitalization fee can be reimbursed by the local New Agricultural Cooperative or medical insurance by 40%;-50%; so that parents generally only need to pay about 30% of the total treatment cost out of pocket;. For particularly poor families, we can help apply for joint funding from multiple funds. Parents who need financial support from the fund and meet the application requirements should contact us for a paper or electronic version of the application form.
