ERCP, a minimally invasive treatment for bile duct stones, the cost of the procedure will usually be around 20,000 yuan at present. This is the cost before reimbursement, the actual cost spent, and the type of health insurance and reimbursement rate are related to the cost before reimbursement. Because ERCP is a minimally invasive treatment, it requires contrast, lithotomy mesh, lithotomy balloon, papillotomy instruments, and nasobiliary tubes, which are all necessary for minimally invasive treatment and are disposable consumables, and the reimbursement rate is relatively low. Because the more minimally invasive, more disposable consumables are needed. Usually, the cost of ERCP in hospitals is around 20,000, depending on the type of medical insurance and the reimbursement rate.
