As of 1/1/2012 the way services are charged has changed in all Hospitals. Until then, Social Security covered hospitalization costs for people insured with them, based on the invoices for materials, medication and days of hospital stay. The Ministry of Health implemented the ΚΕΝ-DRGs System concerning Diagnosis-Related Groups. According to this new system, charges are based on the Code Number of the category of the patient's condition, which corresponds to a fixed charge for all hospitals.
