Hospitalization costs are partly reimbursed by health insurance, at 80%, and your mutual reimburses the remaining 20%. Excess fees, accommodation costs, comfort expenses can increase the bill and your out-of-pocket costs if you don't have good mutual insurance.
A day of hospitalization costs on average nearly 1,400 euros in medical department, 1,700 euros in surgical department and more than 3,000 euros in intensive care. The deadline for reimbursement of medical expenses is subject to their transmission and also varies depending on the nature of medical procedures and care.
