The term dialysis refers to the abbreviation of renal replacement therapy, which is available in two forms: hemodialysis and peritoneal dialysis. Hemodialysis is divided into special modalities such as normal hemodialysis, hemofiltration dialysis and hemoperfusion. The cost of peritoneal dialysis varies from about$30-50 per session, which needs to be done about 4 times/day, and the total cost is about$200. The cost of ordinary hemodialysis is around 500 RMB/session, which can be reimbursed between 90%-95% according to the local medical insurance policy and the price regulations of the price bureau, and patients can usually finish it by paying 10-30 RMB out of pocket. Special dialysis methods such as hemofiltration dialysis and hemoperfusion dialysis cost around 1500 yuan per session, and patients need to pay 300-400 yuan out of pocket after reimbursement according to the proportion.
