Blood purification can be divided into peritoneal dialysis, hemodialysis, and hemofiltration, with different prices. If the patient is on peritoneal dialysis, the cost of one bag of peritoneal dialysis solution is around 40 RMB, and 2-3 bags can be used daily, and long-term adherence is required every day. In case of hemodialysis once, the cost is between 400-500 RMB, and the treatment can be performed 2-3 times a week. In case of hemofiltration, the cost is between 2000-3000 RMB once, so the cost of different purification varies, and the appropriate treatment cost is chosen according to the individual’s specific situation. At present, the state subsidizes major diseases for chronic renal failure, and the cost of hemodialysis is 38 RMB once for employees’ medical insurance and 100 RMB each time for residents’ medical insurance, so it is important to determine the appropriate treatment plan for you according to the specific local policies.
